Ensure a minimum capacity of 4 bytes when allocating the buffer, this is the max size of a UTF-8 character. However, the java length representation is being used in this code for the byte buffer allocation, which may be too small for a single utf-8 character. 2. Use buffer.clear() instead of the second buffer.flip() .

Previously, metadata about the number of rows in the page was not easily accessible or propagated across multiple paginated requests (e.g., when calling `getNextPage()`). This change: 1. Adds a `rowsInPage` field and builder method to the `@AutoValue` `TableResult` class. 2. Populates `rowsInPage` during initial page creation in `BigQueryImpl` and empty results in `Job.java`. 3. Updates `TableResult.getNextPage()` to calculate the size of values for subsequent pages via `Iterables.size` (which is $O(1)$ for materialized lists) and sets it on the returned `TableResult` pages. 4. Updates unit test assertions in `TableResultTest.java` and `SerializationTest.java` to verify that `rowsInPage` is populated and propagated correctly. ## Key Changes - **`TableResult.java`**: Added `getRowsInPage()`, builder method `setRowsInPage()`, and updated `getNextPage()` to pass down the calculated row count for the next page. - **`BigQueryImpl.java`**: Set `rowsInPage` on initial query results page creation. - **`TableResultTest.java`**: Added assertions to verify that `rowsInPage` is correctly populated for both the first page and subsequent pages. --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> --- .../cloud/bigquery/jdbc/BigQueryStatement.java | 4 +++- .../google/cloud/bigquery/BigQueryImpl.java | 3 +++ .../java/com/google/cloud/bigquery/Job.java | 1 + .../com/google/cloud/bigquery/TableResult.java | 18 +++++++++++++++--- .../cloud/bigquery/SerializationTest.java | 1 + .../google/cloud/bigquery/TableResultTest.java | 11 ++++++++++- 6 files changed, 33 insertions(+), 5 deletions(-) diff --git a/java-bigquery-jdbc/src/main/java/com/google/cloud/bigquery/jdbc/BigQueryStatement.java b/java-bigquery-jdbc/src/main/java/com/google/cloud/bigquery/jdbc/BigQueryStatement.java index 0d4d94175b8d..09cc6cda6940 100644 --- a/java-bigquery-jdbc/src/main/java/com/google/cloud/bigquery/jdbc/BigQueryStatement.java +++ b/java-bigquery-jdbc/src/main/java/com/google/cloud/bigquery/jdbc/BigQueryStatement.java @@ -1028,7 +1028,9 @@ private boolean meetsReadRatio(TableResult results) { return false; } - long pageSize = querySettings.getMaxResultPerPage(); + Long rowsInPage = results.getRowsInPage(); + long pageSize = + (rowsInPage != null && rowsInPage > 0) ? rowsInPage : querySettings.getMaxResultPerPage(); // Prevent division by zero due to potential overflows/empty sets: if (pageSize <= 0) { diff --git a/java-bigquery/google-cloud-bigquery/src/main/java/com/google/cloud/bigquery/BigQueryImpl.java b/java-bigquery/google-cloud-bigquery/src/main/java/com/google/cloud/bigquery/BigQueryImpl.java index 74c9ce60e84f..447fe916c5db 100644 --- a/java-bigquery/google-cloud-bigquery/src/main/java/com/google/cloud/bigquery/BigQueryImpl.java +++ b/java-bigquery/google-cloud-bigquery/src/main/java/com/google/cloud/bigquery/BigQueryImpl.java @@ -1691,6 +1691,7 @@ && getOptions().getOpenTelemetryTracer() != null) { .setSchema(schema) .setTotalRows(data.y()) .setPageNoSchema(data.x()) + .setRowsInPage((long) Iterables.size(data.x().getValues())) .build(); } finally { if (tableDataList != null) { @@ -2022,6 +2023,7 @@ public com.google.api.services.bigquery.model.QueryResponse call() .setJobId(jobId) .setQueryId(results.getQueryId()) .setJobCreationReason(JobCreationReason.fromPb(results.getJobCreationReason())) + .setRowsInPage(results.getRows() != null ?

Methods
MethodDescriptionMethod Variants

UpdateAclConfig

Default ACL configuration for use in a location of a customer's project. Updates will only reflect to new data stores. Existing data stores will still use the old value.

 + *

Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *
    + *

  • updateAclConfig(UpdateAclConfigRequest request) + *

+ *

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *
    + *

  • updateAclConfigCallable() + *

+ *

GetAclConfig

Gets the [AclConfig][google.cloud.discoveryengine.v1beta.AclConfig].

 + *

Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *
    + *

  • getAclConfig(GetAclConfigRequest request) + *

+ *

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *
    + *

  • getAclConfig(AclConfigName name) + *

Many parameters require resource names to be formatted in a particular way. To assist with + * these names, this class includes a format method for each type of name, and additionally a parse + * method to extract the individual identifiers contained within names that are returned. + * + *

This class can be customized by passing in a custom instance of AclConfigServiceSettings to + * create(). For example: + * + *

Many parameters require resource names to be formatted in a particular way. To assist with + * these names, this class includes a format method for each type of name, and additionally a parse + * method to extract the individual identifiers contained within names that are returned. + * + *

This class can be customized by passing in a custom instance of AssistantServiceSettings to + * create(). For example: + * + *

Methods
MethodDescriptionMethod Variants

UpdateCmekConfig

Provisions a CMEK key for use in a location of a customer's project. This method will also conduct location validation on the provided cmekConfig to make sure the key is valid and can be used in the selected location.

 + *

Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *
    + *

  • updateCmekConfigAsync(UpdateCmekConfigRequest request) + *

+ *

Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

+ *
    + *

+ *
    + *

  • deleteCmekConfigAsync(DeleteCmekConfigRequest request) + *

+ *

Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

+ *
    + *

  • deleteCmekConfigAsync(CmekConfigName name) + *

  • deleteCmekConfigAsync(String name) + *

+ *

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *
    + *

See the individual methods for example code. + * + *

Many parameters require resource names to be formatted in a particular way. To assist with + * these names, this class includes a format method for each type of name, and additionally a parse + * method to extract the individual identifiers contained within names that are returned. + * + *

This class can be customized by passing in a custom instance of CmekConfigServiceSettings to + * create(). For example: + * + *

To customize credentials: + * + * 

{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * CmekConfigServiceSettings cmekConfigServiceSettings =
+ *     CmekConfigServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * CmekConfigServiceClient cmekConfigServiceClient =
+ *     CmekConfigServiceClient.create(cmekConfigServiceSettings);
+ * }
+ * + *

To customize the endpoint: + * + * 

{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * CmekConfigServiceSettings cmekConfigServiceSettings =
+ *     CmekConfigServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * CmekConfigServiceClient cmekConfigServiceClient =
+ *     CmekConfigServiceClient.create(cmekConfigServiceSettings);
+ * }
+ * + *

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over + * the wire: + * + * 

{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:

            • The default service address (discoveryengine.googleapis.com) and default port (443) are + * used. + *

+/**
+ * Settings class to configure an instance of {@link UserLicenseServiceClient}.
+ *
+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of listLicenseConfigsUsageStats:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserLicenseServiceSettings.Builder userLicenseServiceSettingsBuilder =
+ *     UserLicenseServiceSettings.newBuilder();
+ * userLicenseServiceSettingsBuilder
+ *     .listLicenseConfigsUsageStatsSettings()
+ *     .setRetrySettings(
+ *         userLicenseServiceSettingsBuilder
+ *             .listLicenseConfigsUsageStatsSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * UserLicenseServiceSettings userLicenseServiceSettings =
+ *     userLicenseServiceSettingsBuilder.build();
+ * }
            
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
            To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for batchUpdateUserLicenses:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserLicenseServiceSettings.Builder userLicenseServiceSettingsBuilder =
+ *     UserLicenseServiceSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * userLicenseServiceSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Service Description: Service for managing User Stores.
+ *
+ * 
            This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (UserStoreServiceClient userStoreServiceClient = UserStoreServiceClient.create()) {
+ *   UserStoreName name = UserStoreName.of("[PROJECT]", "[LOCATION]", "[USER_STORE]");
+ *   UserStore response = userStoreServiceClient.getUserStore(name);
+ * }
+ * }
            
+ *
+ * 
            Note: close() needs to be called on the UserStoreServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
+ *    
+ *    
+ *

            Methods
            MethodDescriptionMethod Variants
             GetUserStore
             Gets the User Store.
            		
+ *      
            Request object method variants only take one parameter, a request object, which must be constructed before the call.
            
+ *      
              
+ *           
            •  getUserStore(GetUserStoreRequest request)
+ *      
            
+ *      
            "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.
            
+ *      
              
+ *           
            •  getUserStore(UserStoreName name)
+ *           
            •  getUserStore(String name)
+ *      
            
+ *      
            Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
            
+ *      
              
+ *           
            •  getUserStoreCallable()
+ *      
            
+ *       
             UpdateUserStore
             Updates the User Store.
            		
+ *      
            Request object method variants only take one parameter, a request object, which must be constructed before the call.
            
+ *      
              
+ *           
            •  updateUserStore(UpdateUserStoreRequest request)
+ *      
            
+ *      
            "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

            Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *
+ * 
            See the individual methods for example code.
+ *
+ * 
            Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
            This class can be customized by passing in a custom instance of UserStoreServiceSettings to
+ * create(). For example:
+ *
+ * 
            To customize credentials:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserStoreServiceSettings userStoreServiceSettings =
+ *     UserStoreServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * UserStoreServiceClient userStoreServiceClient =
+ *     UserStoreServiceClient.create(userStoreServiceSettings);
+ * }
            
+ *
+ * 
            To customize the endpoint:
+ *

+/**
+ * Settings class to configure an instance of {@link UserStoreServiceClient}.
+ *
+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getUserStore:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserStoreServiceSettings.Builder userStoreServiceSettingsBuilder =
+ *     UserStoreServiceSettings.newBuilder();
+ * userStoreServiceSettingsBuilder
+ *     .getUserStoreSettings()
+ *     .setRetrySettings(
+ *         userStoreServiceSettingsBuilder
+ *             .getUserStoreSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * UserStoreServiceSettings userStoreServiceSettings = userStoreServiceSettingsBuilder.build();
+ * }
            
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

            The default instance has everything set to sensible defaults: + * + *

              + *
            • The default service address (discoveryengine.googleapis.com) and default port (443) are + * used. + *
            • Credentials are acquired automatically through Application Default Credentials. + *
            • Retries are configured for idempotent methods but not for non-idempotent methods. + *
            + * + *

            The builder of this class is recursive, so contained classes are themselves builders. When + * build() is called, the tree of builders is called to create the complete settings object. + * + *

            For example, to set the + * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings) + * of createIdentityMappingStore: + * + * 

            {@code

              + *
            • The default service address (discoveryengine.googleapis.com) and default port (443) are + * used. + *
            • Credentials are acquired automatically through Application Default Credentials. + *
            • Retries are configured for idempotent methods but not for non-idempotent methods. + *

            The builder of this class is recursive, so contained classes are themselves builders. When + * build() is called, the tree of builders is called to create the complete settings object. + * + *

+/**
+ * Settings class to configure an instance of {@link UserLicenseServiceStub}.
+ *
+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of listLicenseConfigsUsageStats:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserLicenseServiceStubSettings.Builder userLicenseServiceSettingsBuilder =
+ *     UserLicenseServiceStubSettings.newBuilder();
+ * userLicenseServiceSettingsBuilder
+ *     .listLicenseConfigsUsageStatsSettings()
+ *     .setRetrySettings(
+ *         userLicenseServiceSettingsBuilder
+ *             .listLicenseConfigsUsageStatsSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * UserLicenseServiceStubSettings userLicenseServiceSettings =
+ *     userLicenseServiceSettingsBuilder.build();
+ * }
            
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
            To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for batchUpdateUserLicenses:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserLicenseServiceStubSettings.Builder userLicenseServiceSettingsBuilder =
+ *     UserLicenseServiceStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * userLicenseServiceSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+ * Settings class to configure an instance of {@link UserStoreServiceStub}.

+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getUserStore:
+ *
+ *

+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:

+     * This score determines how semantically similar a search query is to a
+     * document.
+     * * `keyword_similarity_score`: keyword match adjustment uses the Best
+     * Match 25 (BM25) ranking function. This score is calculated using a
+     * probabilistic model to estimate the probability that a document is
+     * relevant to a given query.
+     * * `relevance_score`: semantic relevance adjustment that uses a
+     * proprietary Google model to determine the meaning and intent behind a
+     * user's query in context with the content in the documents.
+     * * `pctr_rank`: predicted conversion rate adjustment as a rank use
+     * predicted Click-through rate (pCTR) to gauge the relevance and
+     * attractiveness of a search result from a user's perspective. A higher
+     * pCTR suggests that the result is more likely to satisfy the user's query
+     * and intent, making it a valuable signal for ranking.
+     * * `freshness_rank`: freshness adjustment as a rank
+     * * `document_age`: The time in hours elapsed since the document was last
+     * updated, a floating-point number (e.g., 0.25 means 15 minutes).
+     * * `topicality_rank`: topicality adjustment as a rank. Uses proprietary

      *
+     * If
+     * [ranking_expression_backend][google.cloud.discoveryengine.v1beta.SearchRequest.ranking_expression_backend]
+     * is set to `RANK_BY_FORMULA`, the following expression types (and
+     * combinations of those chained using + or
+     * * operators) are supported:
      *
-     * 
            -     * The query expansion specification that specifies the conditions under which
-     * query expansion occurs.
+     * * `double`
+     * * `signal`
+     * * `log(signal)`
+     * * `exp(signal)`
+     * * `rr(signal, double > 0)`  -- reciprocal rank transformation with second
+     * argument being a denominator constant.
+     * * `is_nan(signal)` -- returns 0 if signal is NaN, 1 otherwise.
+     * * `fill_nan(signal1, signal2 | double)` -- if signal1 is NaN, returns
+     * signal2 | double, else returns signal1.
+     *
+     * Here are a few examples of ranking formulas that use the supported
+     * ranking expression types:
+     *
+     * - `0.2 * semantic_similarity_score + 0.8 * log(keyword_similarity_score)`
+     * -- mostly rank by the logarithm of `keyword_similarity_score` with slight
+     * `semantic_smilarity_score` adjustment.
+     * - `0.2 * exp(fill_nan(semantic_similarity_score, 0)) + 0.3 *
+     * is_nan(keyword_similarity_score)` -- rank by the exponent of
+     * `semantic_similarity_score` filling the value with 0 if it's NaN, also
+     * add constant 0.3 adjustment to the final score if
+     * `semantic_similarity_score` is NaN.
+     * - `0.2 * rr(semantic_similarity_score, 16) + 0.8 *
+     * rr(keyword_similarity_score, 16)` -- mostly rank by the reciprocal rank
+     * of `keyword_similarity_score` with slight adjustment of reciprocal rank
+     * of `semantic_smilarity_score`.
+     *
+     * The following signals are supported:
+     *
+     * * `semantic_similarity_score`: semantic similarity adjustment that is
+     * calculated using the embeddings generated by a proprietary Google model.
+     * This score determines how semantically similar a search query is to a
+     * document.
+     * * `keyword_similarity_score`: keyword match adjustment uses the Best
+     * Match 25 (BM25) ranking function. This score is calculated using a
+     * probabilistic model to estimate the probability that a document is
+     * relevant to a given query.
+     * * `relevance_score`: semantic relevance adjustment that uses a
+     * proprietary Google model to determine the meaning and intent behind a
+     * user's query in context with the content in the documents.
+     * * `pctr_rank`: predicted conversion rate adjustment as a rank use
+     * predicted Click-through rate (pCTR) to gauge the relevance and
+     * attractiveness of a search result from a user's perspective. A higher
+     * pCTR suggests that the result is more likely to satisfy the user's query
+     * and intent, making it a valuable signal for ranking.
+     * * `freshness_rank`: freshness adjustment as a rank
+     * * `document_age`: The time in hours elapsed since the document was last
+     * updated, a floating-point number (e.g., 0.25 means 15 minutes).
+     * * `topicality_rank`: topicality adjustment as a rank. Uses proprietary
+     * Google model to determine the keyword-based overlap between the query and
+     * the document.
+     * * `base_rank`: the default rank of the result
+     * * `media_actor_match`: whether the media actor matches the query
+     * * `media_director_match`: whether the media director matches the query
+     * * `media_genre_match`: whether the media genre matches the query
+     * * `media_language_match`: whether the media language matches the query
+     * * `media_title_match`: whether the media title matches the query
+     * * `media_prefix_similarity_rank`: prefix similarity rank for media
+     * results

-     * - `0.2 * semantic_similarity_score + 0.8 * log(keyword_similarity_score)`
-     * -- mostly rank by the logarithm of `keyword_similarity_score` with slight

-     * - `0.2 * exp(fill_nan(semantic_similarity_score, 0)) + 0.3 *
-     * is_nan(keyword_similarity_score)` -- rank by the exponent of
-     * `semantic_similarity_score` filling the value with 0 if it's NaN, also
-     * add constant 0.3 adjustment to the final score if
-     * `semantic_similarity_score` is NaN.
-     * - `0.2 * rr(semantic_similarity_score, 16) + 0.8 *
-     * rr(keyword_similarity_score, 16)` -- mostly rank by the reciprocal rank
-     * of `keyword_similarity_score` with slight adjustment of reciprocal rank
-     * of `semantic_smilarity_score`.
-     *
-     * The following signals are supported:
-     *
-     * * `semantic_similarity_score`: semantic similarity adjustment that is
-     * calculated using the embeddings generated by a proprietary Google model.
-     * This score determines how semantically similar a search query is to a
-     * document.
-     * * `keyword_similarity_score`: keyword match adjustment uses the Best
-     * Match 25 (BM25) ranking function. This score is calculated using a
-     * probabilistic model to estimate the probability that a document is
-     * relevant to a given query.
-     * * `relevance_score`: semantic relevance adjustment that uses a
-     * proprietary Google model to determine the meaning and intent behind a
-     * user's query in context with the content in the documents.
-     * * `pctr_rank`: predicted conversion rate adjustment as a rank use
-     * predicted Click-through rate (pCTR) to gauge the relevance and
-     * attractiveness of a search result from a user's perspective. A higher
-     * pCTR suggests that the result is more likely to satisfy the user's query
-     * and intent, making it a valuable signal for ranking.
-     * * `freshness_rank`: freshness adjustment as a rank
-     * * `document_age`: The time in hours elapsed since the document was last
-     * updated, a floating-point number (e.g., 0.25 means 15 minutes).
-     * * `topicality_rank`: topicality adjustment as a rank. Uses proprietary

Subject: [PATCH 25/82] feat(bigquery): add internal listProjects API to core
 client (#13429)

b/521443900

This PR introduces support for fetching a list of GCP projects via the
BigQuery API. This functionality is being exposed primarily to support
cross-project dataset resolution in the native BigQuery JDBC driver.

**Changes included:**
* **Domain Model:** Added `Project` domain model representing a BigQuery
project (`@BetaApi`).
* **Client Interface:** Added `listProjects(ProjectListOption...
options)` to the `BigQuery` client interface, marked as `@InternalApi`
to preserve the public GA surface.
* **SPI Layer:** Added `listProjects` mapping to `BigQueryRpc` and
implemented the underlying HTTP execution in `HttpBigQueryRpc`,
including pagination and OpenTelemetry tracing support.
* **Implementation:** Implemented `ProjectPageFetcher` inside
`BigQueryImpl` to seamlessly handle paginated project results.
* **Testing:** Added unit test coverage in `BigQueryImplTest` and
`HttpBigQueryRpcTest`.

Subject: [PATCH 26/82] refactor(test): migrate remaining wait loops to
 Awaitility in GAX tests (#13484)

This PR migrates all remaining wait loops and polling blocks in GAX
tests to use Awaitility. This is the second part of b/505479343,
following the initial introduction of Awaitility in #13458.

Specifically, this migrates:
- Semaphore64Test: replaced mock thread wait loops with Awaitility state
waiting.
- ScheduledRetryingExecutorTest: migrated future attempt checking,
attempt cancellation wait, and first attempt latch count down to
Awaitility.
- BatcherImplTest: converted GC loops and thread state polling blocks to
Awaitility.

Subject: [PATCH 28/82] fix(bigquery): route JOB_CREATION_REQUIRED through fast
 query path (#13437)

Routes queries under `JobCreationMode.JOB_CREATION_REQUIRED` to the fast
query path (`jobs.query` API / 1 RPC) to avoid the slow fallback path
(`jobs.insert` API / 2 RPCs).


https://docs.cloud.google.com/bigquery/docs/reference/rest/v2/jobs/query#QueryResponse
says:
> object
([JobReference](https://docs.cloud.google.com/bigquery/docs/reference/rest/v2/JobReference))
>
> Reference to the Job that was created to run the query. This field
will be present even if the original request timed out, in which case
jobs.getQueryResults can be used to read the results once the query has
completed. Since this API only returns the first page of results,
subsequent pages can be fetched via the same mechanism
(jobs.getQueryResults).
>
> If jobCreationMode was set to JOB_CREATION_OPTIONAL and the query
completes without creating a job, this field will be empty.

Thus, routing `JOB_CREATION_REQUIRED` through the fast path is
preferred.

+# Java Bigtable Development Guidelines
+
+When developing or modifying code within the `java-bigtable` directory, you must strictly follow these rules and perform these actions:
+
+## 1. Source Control
+- **Always** pull the latest changes from the `main` branch of `git@github.com:googleapis/google-cloud-java.git` before starting work.
+- Checkout a new branch for your development instead of committing directly to `main`.
+
+## 2. Unit Testing
+- **Always write unit tests** for any new logic or modifications you implement.
+- Follow **JUnit 5** conventions for writing and structuring tests (e.g., using `@Test`, `@BeforeEach`, etc., from `org.junit.jupiter.api`). 
+- Do not use JUnit 4 unless modifying an existing file that hasn't been migrated yet, but for new tests default to JUnit 5.
+
+## 3. Clean Up Imports
+- After writing or updating code, **always** check that imports are properly cleaned up.
+- Avoid using fully qualified class names (e.g., `x.y.z.Class`) directly inline in the code.
+- Ensure all required classes are imported in the header of the Java file.
+- Remove any unused imports.
+
+## 4. Code Formatting
+- Automatically format the code using the `fmt-maven-plugin`.
+- Before finalizing your changes, run the following command in the terminal from the `java-bigtable` directory or the relevant module directory:
+  ```bash
+  mvn com.spotify.fmt:fmt-maven-plugin:format
+  ```
+- **Troubleshooting**: If the formatting command fails, it is usually because of an incompatible JDK version. Ensure you are running it in an environment with the correct JDK version for the project (typically 17+, depending on the project configuration).

+# Google Agent Registry Client for Java
+
+Java idiomatic client for [Agent Registry][product-docs].
+
+[![Maven][maven-version-image]][maven-version-link]
+![Stability][stability-image]
+
+- [Product Documentation][product-docs]
+- [Client Library Documentation][javadocs]
+
+> Note: This client is a work-in-progress, and may occasionally
+> make backwards-incompatible changes.
+
+
+## Quickstart
+
+
+If you are using Maven with [BOM][libraries-bom], add this to your pom.xml file:
+
+```xml
+
+  
+    
+      com.google.cloud
+      libraries-bom
+      26.83.0
+      pom
+      import
+    
+  
+
+
+
+  
+    com.google.cloud
+    google-cloud-agentregistry
+  
+
+```
+
+If you are using Maven without the BOM, add this to your dependencies:
+
+
+```xml
+
+  com.google.cloud
+  google-cloud-agentregistry
+  0.0.0
+
+```
+
+If you are using Gradle without BOM, add this to your dependencies:
+
+```Groovy
+implementation 'com.google.cloud:google-cloud-agentregistry:0.0.0'
+```
+
+If you are using SBT, add this to your dependencies:
+
+```Scala
+libraryDependencies += "com.google.cloud" % "google-cloud-agentregistry" % "0.0.0"
+```
+
+## Authentication
+
+See the [Authentication][authentication] section in the base directory's README.
+
+## Authorization
+
+The client application making API calls must be granted [authorization scopes][auth-scopes] required for the desired Agent Registry APIs, and the authenticated principal must have the [IAM role(s)][predefined-iam-roles] required to access GCP resources using the Agent Registry API calls.
+
+## Getting Started
+
+### Prerequisites
+
+You will need a [Google Cloud Platform Console][developer-console] project with the Agent Registry [API enabled][enable-api].
+You will need to [enable billing][enable-billing] to use Google Agent Registry.
+[Follow these instructions][create-project] to get your project set up. You will also need to set up the local development environment by
+[installing the Google Cloud Command Line Interface][cloud-cli] and running the following commands in command line:
+`gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.
+
+### Installation and setup
+
+You'll need to obtain the `google-cloud-agentregistry` library.  See the [Quickstart](#quickstart) section
+to add `google-cloud-agentregistry` as a dependency in your code.
+
+## About Agent Registry
+
+
+[Agent Registry][product-docs] Agent Registry is a centralized, unified catalog that lets you store,
+discover, and govern Model Context Protocol (MCP) servers, tools, and AI
+agents within Google Cloud.
+
+See the [Agent Registry client library docs][javadocs] to learn how to
+use this Agent Registry Client Library.
+
+
+
+
+
+
+## Troubleshooting
+
+To get help, follow the instructions in the [shared Troubleshooting document][troubleshooting].
+
+## Transport
+
+Agent Registry uses both gRPC and HTTP/JSON for the transport layer.
+
+## Supported Java Versions
+
+Java 8 or above is required for using this client.
+
+Google's Java client libraries,
+[Google Cloud Client Libraries][cloudlibs]
+and
+[Google Cloud API Libraries][apilibs],
+follow the
+[Oracle Java SE support roadmap][oracle]
+(see the Oracle Java SE Product Releases section).
+
+### For new development
+
+In general, new feature development occurs with support for the lowest Java
+LTS version covered by  Oracle's Premier Support (which typically lasts 5 years
+from initial General Availability). If the minimum required JVM for a given
+library is changed, it is accompanied by a [semver][semver] major release.
+
+Java 11 and (in September 2021) Java 17 are the best choices for new
+development.
+
+### Keeping production systems current
+
+Google tests its client libraries with all current LTS versions covered by
+Oracle's Extended Support (which typically lasts 8 years from initial
+General Availability).
+
+#### Legacy support
+
+Google's client libraries support legacy versions of Java runtimes with long
+term stable libraries that don't receive feature updates on a best efforts basis
+as it may not be possible to backport all patches.
+
+Google provides updates on a best efforts basis to apps that continue to use
+Java 7, though apps might need to upgrade to current versions of the library
+that supports their JVM.
+
+#### Where to find specific information
+
+The latest versions and the supported Java versions are identified on
+the individual GitHub repository `github.com/GoogleAPIs/java-SERVICENAME`
+and on [google-cloud-java][g-c-j].
+
+## Versioning
+
+
+This library follows [Semantic Versioning](http://semver.org/).
+
+
+It is currently in major version zero (``0.y.z``), which means that anything may change at any time
+and the public API should not be considered stable.
+
+

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: Service for managing Agents, Endpoints, McpServers, Services, and Bindings.
+ *
+ * 
            This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (AgentRegistryClient agentRegistryClient = AgentRegistryClient.create()) {
+ *   AgentName name = AgentName.of("[PROJECT]", "[LOCATION]", "[AGENT]");
+ *   Agent response = agentRegistryClient.getAgent(name);
+ * }
+ * }
            
+ *
+ * 
            Note: close() needs to be called on the AgentRegistryClient object to clean up resources such
+ * as threads. In the example above, try-with-resources is used, which automatically calls close().

            Many parameters require resource names to be formatted in a particular way. To assist with

+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:

+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * AgentRegistrySettings agentRegistrySettings =
+ *     AgentRegistrySettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * AgentRegistryClient agentRegistryClient = AgentRegistryClient.create(agentRegistrySettings);
+ * }
            
+ *
+ * 
            To customize the endpoint:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.

+ * AgentRegistrySettings agentRegistrySettings =
+ *     AgentRegistrySettings.newBuilder().setEndpoint(myEndpoint).build();
+ * AgentRegistryClient agentRegistryClient = AgentRegistryClient.create(agentRegistrySettings);
+ * }
            
+ *
+ * 
            To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link AgentRegistryClient}.
+ *
+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (agentregistry.googleapis.com) and default port (443) are used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getAgent:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * AgentRegistrySettings.Builder agentRegistrySettingsBuilder = AgentRegistrySettings.newBuilder();
+ * agentRegistrySettingsBuilder
+ *     .getAgentSettings()
+ *     .setRetrySettings(
+ *         agentRegistrySettingsBuilder
+ *             .getAgentSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * AgentRegistrySettings agentRegistrySettings = agentRegistrySettingsBuilder.build();
+ * }
            
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
            To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for createService:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * AgentRegistrySettings.Builder agentRegistrySettingsBuilder = AgentRegistrySettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * agentRegistrySettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link AgentRegistryStub}.
+ *
+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (agentregistry.googleapis.com) and default port (443) are used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getAgent:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * AgentRegistryStubSettings.Builder agentRegistrySettingsBuilder =
+ *     AgentRegistryStubSettings.newBuilder();
+ * agentRegistrySettingsBuilder
+ *     .getAgentSettings()
+ *     .setRetrySettings(
+ *         agentRegistrySettingsBuilder
+ *             .getAgentSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * AgentRegistryStubSettings agentRegistrySettings = agentRegistrySettingsBuilder.build();
+ * }
            
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
            To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for createService:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * AgentRegistryStubSettings.Builder agentRegistrySettingsBuilder =
+ *     AgentRegistryStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * agentRegistrySettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+ * errors.
+ *
+ * 
            This class provides the ability to make remote calls to the backing service through method

+ *   }
+ * }
+ * }
            
+ *
+ * 
            Note: close() needs to be called on the RuleExecutionErrorServiceClient object to clean up

            Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

            See the individual methods for example code.
+ *
+ * 
            Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
            This class can be customized by passing in a custom instance of
+ * RuleExecutionErrorServiceSettings to create(). For example:
+ *
+ * 
            To customize credentials:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RuleExecutionErrorServiceSettings ruleExecutionErrorServiceSettings =
+ *     RuleExecutionErrorServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * RuleExecutionErrorServiceClient ruleExecutionErrorServiceClient =
+ *     RuleExecutionErrorServiceClient.create(ruleExecutionErrorServiceSettings);
+ * }
            
+ *
+ * 
            To customize the endpoint:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RuleExecutionErrorServiceSettings ruleExecutionErrorServiceSettings =
+ *     RuleExecutionErrorServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * RuleExecutionErrorServiceClient ruleExecutionErrorServiceClient =
+ *     RuleExecutionErrorServiceClient.create(ruleExecutionErrorServiceSettings);
+ * }
            
+ *
+ * 
            To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in

+/**
+ * Settings class to configure an instance of {@link RuleExecutionErrorServiceClient}.
+ *
+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (chronicle.googleapis.com) and default port (443) are used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of listRuleExecutionErrors:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RuleExecutionErrorServiceSettings.Builder ruleExecutionErrorServiceSettingsBuilder =
+ *     RuleExecutionErrorServiceSettings.newBuilder();
+ * ruleExecutionErrorServiceSettingsBuilder
+ *     .listRuleExecutionErrorsSettings()
+ *     .setRetrySettings(
+ *         ruleExecutionErrorServiceSettingsBuilder
+ *             .listRuleExecutionErrorsSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * RuleExecutionErrorServiceSettings ruleExecutionErrorServiceSettings =
+ *     ruleExecutionErrorServiceSettingsBuilder.build();
+ * }
            
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+/**
+ * Settings class to configure an instance of {@link RuleExecutionErrorServiceStub}.
+ *
+ * 
            The default instance has everything set to sensible defaults:
+ *
+ * 
              
+ *   
            • The default service address (chronicle.googleapis.com) and default port (443) are used.
+ *   
            • Credentials are acquired automatically through Application Default Credentials.
+ *   
            • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
            
+ *
+ * 
            The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
            For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of listRuleExecutionErrors:
+ *
+ * 
            {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RuleExecutionErrorServiceStubSettings.Builder ruleExecutionErrorServiceSettingsBuilder =

Subject: [PATCH 36/82] feat(bigquery-jdbc): migrate statement execution thread
 tracking to connection-scoped executor (#13454)

b/519201498

This PR migrates the asynchronous processing tasks of the JDBC driver
away from the legacy static global thread pool (`queryTaskExecutor`) to
the modern, connection-scoped `ExecutorService`
(`connection.getExecutorService()`).

### Key Changes
1. **Statement & Stream Refactoring**:
   - Removed the static `queryTaskExecutor` from `BigQueryStatement`.
- Updated `populateArrowBufferedQueue` to submit streaming and buffering
tasks to the connection-scoped executor pool.
- Converted background thread tracking in `BigQueryStatement` and
`BigQueryArrowResultSet` from raw `Thread` references to modern,
cancelable `Future` task handles.

2. **Isolated Backward-Compatibility Wrapper**:
- Isolated the legacy raw thread wrapping to `BigQueryDatabaseMetaData`
(which is still pending future refactoring to the executor pool).
- Implemented a temporary `wrapThread(Thread)` helper method inside
`BigQueryDatabaseMetaData` to wrap raw background threads into
cancelable `Future` adapters on the fly before passing them to the
result set.
- Hardened the anonymous `Future` wrapper state tracking to strictly
satisfy the `Future` specification contract (handling `cancel`,
`isCancelled`, and `isDone` correctly using a volatile boolean flag to
prevent duplicate cancellation triggers).

* **`bigQueryRpc.cancelSkipExceptionTranslation`** (via `cancel(...)` —
resolves `b/467066417`)

### 4. IAM & Permissions
* **`bigQueryRpc.testIamPermissionsSkipExceptionTranslation`** (via
`testIamPermissions(...)`)

### 5. Routine Creation (Specifically added for UDF Test)
* **`bigQueryRpc.createSkipExceptionTranslation` (Routines only)** (via
`createRoutine(...)` — resolves `b/467066596`)

Subject: [PATCH 44/82] fix(spanner): fail fast when inline-begin DML returns
 no transaction id (#13536)

Sync executeUpdate/executeBatchUpdate and async batchUpdateAsync left
transactionIdFuture unresolved when a begin-requesting DML response
carried no transaction metadata, so commit blocked on the 60s wait and
surfaced DEADLINE_EXCEEDED. Mirror executeUpdateAsync: raise
FAILED_PRECONDITION via onError so the future resolves and the
transaction retries or propagates. Use getId().isEmpty() consistently
and add regression coverage via a mock omit-transaction hook.

Subject: [PATCH 45/82] chore(bigtable): correct sparse-bootstrap dep discovery
 and install ordering (#13523)

The previous script missed cross-project SNAPSHOT deps and could fail on
clean-m2 runs. Fixes:

- Walk regular  edges (not just parent + BOM imports) so
monorepo SNAPSHOTs like api-common-java are discovered.
- Version-aware edge following: skip edges whose declared version
doesn't match the local pom, so pinned released BOM imports (e.g.
google-cloud-pubsub-bom:1.140.0 from google-cloud-jar-parent) aren't
mistakenly followed to the local SNAPSHOT, which created cycles and
phantom projects in the install list.
- Verify the local pom's coord+version matches  before accepting
the  shortcut; the Maven default '../pom.xml' otherwise
resolves to the unrelated repo-root pom.
- Enqueue each project's aggregator /pom.xml when any pom under
it is visited, since 'cd  && mvn' forces Maven to load the
aggregator regardless of -pl.
- Flush the install batch on every top-level project change so
interleaved topo orders (A1, A2, B1, A3 when A3 depends on B1) install
in dep order instead of being collapsed per project.
- Match pom filenames by exact basename so test resources like
src/test/resources/gax-example-pom.xml aren't picked up as modules.

+# Google Cloud Shared Build Configs
+
+Shared Maven build configuration for Google Cloud Java client libraries.
+This is not intended for library users.
+
+[![Maven][maven-version-image]][maven-version-link]
+
+## Quickstart
+
+[//]: # ({x-version-update-start:google-cloud-shared-config:released})
+If you are using Maven, use this artifact as your project's parent.
+```xml
+
+  
+    com.google.cloud
+    google-cloud-shared-config
+    1.2.4
+  
+
+```
+[//]: # ({x-version-update-end})
+
+## Versioning
+
+This library follows [Semantic Versioning](http://semver.org/).
+
+It is currently in major version zero (``0.y.z``), which means that anything may change at any time
+and the public API should not be considered stable.
+
+## Usages
+
+Declare this artifact as the parent of Maven projects of Google Cloud libraries.
+This brings useful Maven plugins and their configurations to the Maven projects,
+such as compilations, document generation, and library publication.
+
+### AutoValue
+
+If you want to use AutoValue in your project, place an empty file `EnableAutoValue.txt`
+in the module that requires AutoValue's annotation processing.
+Example pull request: https://github.com/googleapis/java-pubsub/pull/1761/files.

Subject: [PATCH 49/82] feat(auth): Add support for Regional Access Boundaries
 (#13499)

The Regional Access Boundaries PR to main. Contains all the changes
merged to the feature branch rebased on top of main.

P.S. Opening the PR directly to main as feature branch
regional-access-boundaries has drifted from main and opening a
rebased-PR to the feature branch shows 5k+ lines of code diff.

Subject: [PATCH 52/82] chore: Update owlbot to avoid copying generated unit
 tests for pure GAPIC libraries (#13518)

Update all the owlbot hermetic configs to not copy over the GAPIC
generated unit tests. We will instead rely on the showcase tests for
coverage for functionality.

This also updates the template `owlbot.yaml.monorepo.j2` to prevent new
client libraries from copying over the generated unit tests. All future
library generations should only contain the source code.

Part of https://github.com/googleapis/google-cloud-java/issues/13296 to
speed up the CIs (reducing the bulk test times).

Subject: [PATCH 53/82] feat(bigquery-jdbc): respect standard JVM trustStore
 properties by default (#13435)

b/515129164

### Problem
In enterprise corporate networks (e.g. Zscaler), outbound HTTPS traffic
is intercepted by transparent proxies doing SSL MITM (man-in-the-middle)
decryption. The proxy signs its re-encrypted connections with
dynamically generated root CA certificates.

The BigQuery JDBC driver failed to establish TLS connections under these
environments because the underlying client library ignored JVM trust
stores (the standard Java `cacerts` file or custom system properties set
via `-Djavax.net.ssl.trustStore`).
This happened because when direct connections had empty SSL/proxy
settings, the driver returned `null` for `HttpTransportOptions`. This
fallback triggered classpath SPI overrides or legacy defaults which
invoked `GoogleNetHttpTransport.newTrustedTransport()`. That convenience
constructor hardcodes trust exclusively to a bundled `google.p12`
keystore, completely overriding JVM system properties.

### Solution
Simplified the driver's transport instantiation to align with the core
Google Cloud Java SDK's network defaults:
1. **Direct Connections:** Modified `getHttpTransportOptions(...)` to
unconditionally return a transport factory configured with a single
`NetHttpTransport` instance (`new NetHttpTransport.Builder().build()`).
This allows JSSE to handle TLS certificate validation using standard JVM
system properties and `cacerts` natively. Bypassing the SPI loader
prevents classpath hijacking.
2. **Explicit Proxy Connections:** Configured the Apache HTTP client
builder inside `getHttpTransportFactory(...)` to unconditionally call
`httpClientBuilder.useSystemProperties()`. This ensures that even when a
proxy is set in the JDBC URL, Apache HttpClient still honors
system-level properties like `-Djavax.net.ssl.trustStore`.

### Integration Testing: SSL/TLS Validation (`ITLocalSslValidationTest`)
Added `ITLocalSslValidationTest.java` to validate the loading and
enforcement of custom SSL truststore configurations end-to-end.

* **Local Mock HTTPS Server:** Starts a lightweight local HTTPS server
on a random port presenting a self-signed certificate. It mocks
necessary BigQuery backend endpoints (`/queries` and `/jobs`) to satisfy
basic driver query execution.
* **Process Isolation:** Runs each connection check in a separate,
isolated JVM subprocess via `ProcessBuilder`. This is required to bypass
JSSE's JVM-wide caching of the `-Djavax.net.ssl.trustStore` property.
* **Test Coverage:**
* **Negative Case:** Verifies that connection attempts without a
truststore fail with the expected `PKIX path building failed` handshake
error (exit code `1`).
* **Positive Case:** Verifies that connection attempts using our custom
truststore (`localhost-truststore.jks`) succeed and complete query
executions successfully (exit code `0`).
* **CI Integration:** Added to `ITPresubmitTests` to run automatically
on every pull request. Since it uses local mocks, it requires **no GCP
credentials** and executes in **under 2 seconds**.

Subject: [PATCH 57/82] deps: Add org.bouncycastle:bcprov-jdk18on to
 java-shared-dependencies (#13531)

This adds BouncyCastle to the shared dependency BOM. It is required to
implement the OPAQUE PAKE protocol for Spanner Omni authentication
(which relies on Argon2id and low-level Elliptic Curve math not
available in standard Java/Tink).

Bug: b/526057728

Subject: [PATCH 62/82] feat(gapic-generator): Add NullMarked annotation to
 generated classes (#13517)

This PR updates the gapic-generator-java to add the JSpecify @NullMarked
annotation to all generated class declarations. Adding @NullMarked at
the class level defines the class scope as null-safe, establishing that
all unannotated types in method signatures (parameters and return types)
are nonnull able by default. This is the first phase in onboarding the
generated client libraries to compile-time safety validation, see design
doc for more details:
[go/sdk:java-jspecify-null-annotations-gapic](http://goto.google.com/sdk:java-jspecify-null-annotations-gapic)

Classes Annotated:
- Client Classes: AbstractServiceClientClassComposer
- Settings Classes: AbstractServiceSettingsClassComposer and
AbstractServiceStubSettingsClassComposer
- Stub Classes: AbstractServiceStubClassComposer and
AbstractTransportServiceStubClassComposer
- Callable Factories: AbstractServiceCallableFactoryClassComposer
- Resource Names: ResourceNameHelperClassComposer, CommonStrings

Implementation Changes:
- Added JSpecify import statements to class-level generation templates
- Registered NullMarked.class and Nullable.class in TypeStore across all
class composers to ensure references compile and resolve properly

Verification/Testing:
- Please refer to this doc:
https://docs.google.com/document/d/1h126pbTGqSwtJyl35E2_vQjM9gNtmWETYCM7PObcvmQ/edit?tab=t.0#heading=h.s4q06jxocx8b

Revisions:
- Mainly to fix the autogenerator, not related to logic: added goldens +
dependencies for the build

Next Steps:
- In the next PR, will add @Nullable annotations

Subject: [PATCH 63/82] fix(bigquery-jdbc): propagate connection proxy settings
 to auth library (#13539)

b/526579065
https://github.com/googleapis/google-cloud-java/issues/13494

This PR resolves an issue where the BigQuery JDBC driver fails to
connect/authenticate in proxy-enforced network environments, resulting
in authentication timeouts.

### Problem
While the driver successfully parses connection-specific proxy
parameters (`ProxyHost` and `ProxyPort` in the connection string) and
configures the main BigQuery client, it **does not** propagate them to
the Google Auth Library credential objects (used to fetch/refresh OAuth2
access tokens). As a result, token fetch requests bypass the proxy and
attempt direct egress to `oauth2.googleapis.com`, which is blocked by
the firewall.

### Solution
1. **Reordered Constructor:** Updated `BigQueryConnection.java` to parse
HTTP proxy settings and build `HttpTransportOptions` *before*
instantiating credentials.
2. **Propagated Transport Factory:** Extracted the proxy-configured
`HttpTransportFactory` and passed it into the credentials helper
(`BigQueryJdbcOAuthUtility.getCredentials(...)`).
3. **Updated Auth Utility:** Overloaded and updated all authentication
methods inside `BigQueryJdbcOAuthUtility.java`
(`getGoogleServiceAccountCredentials`, `getUserAuthorizer`,
`getExternalAccountAuthCredentials`, and
`getServiceAccountImpersonatedCredentials`) to accept
`HttpTransportFactory` and apply it to their respective credential
builders.

---

## Testing Done

### 1. Unit Tests
Added regression tests to `BigQueryJdbcOAuthUtilityTest.java` to assert
that `HttpTransportFactory` is correctly set on the built credentials:
* `testGetCredentialsPropagatesHttpTransportFactory` (Service Account
Credentials)
* `testGetImpersonatedCredentialsPropagatesHttpTransportFactory`
(Impersonated Credentials)

### 2. Manual Verification
Verified routing in a network-isolated environment using Docker:
* Set up a local **Squid proxy** on port `3128` and a mock HTTPS server
hosting the `/token` endpoint on port `45825` on the host loopback.
* Ran the client verifier container inside an isolated Docker bridge
network (blocking direct access to the host loopback).
* Configured the connection URL string with proxy details:
`;ProxyHost=host.docker.internal;ProxyPort=3128;`.
* **Result:** The connection was established successfully, and the Squid
proxy log recorded the authentication tunnel request:
  `CONNECT localhost:45825 - HIER_DIRECT/::1 -`
* Omitting proxy settings correctly threw a `Connection refused`
exception and left Squid logs empty, proving that proxy routing was
strictly enforced and active.

Subject: [PATCH 64/82] feat(bigquery-jdbc): add `EnableProjectDiscovery`
 connection property for metadata methods (#13344)

b/499078725

This PR implements the `EnableProjectDiscovery` connection property into
the BigQuery JDBC driver. Enabling this property (default `false`)
allows JDBC database metadata methods (like `getCatalogs()` and
`getSchemas()`) to discover and query datasets across all Google Cloud
projects accessible to the client credentials, rather than being
confined to the single default `ProjectId` specified in the connection
URL.

#### Changes
- **Connection Parameter Parsing**: Added parsing for
`EnableProjectDiscovery` in `BigQueryJdbcUrlUtility` and configured it
in `DataSource`.
- **SDK Integration**: Implemented
`BigQueryConnection.getDiscoveredProjects()` to utilize the
`BigQuery.listProjects()` core SDK method
- **Resilience and Caching**:
- Connection-scoped caching is implemented via
`discoveredProjectsCache`.
- **Metadata Integration**: Integrated discovered projects inside
`BigQueryDatabaseMetaData.getAccessibleCatalogNames()` so that catalog
and schema metadata fetches automatically query across all accessible
projects when `EnableProjectDiscovery` is enabled.

Subject: [PATCH 65/82] test(auth): verify GoogleCredentials.fromStream throws
 IOException on invalid JSON (#13473)

Other client libraries (such as Python, Go, and Rust) strictly validate
JSON syntax and reject malformed payload structures immediately. This
test ensures Java maintains parity by asserting that an IOException is
explicitly thrown when ADC JSON parsing fails, preventing silent
fallbacks.

This fills an untested gap in the Java ADC resolution suite.

Subject: [PATCH 66/82] feat(storage): log additional bytes received from GCS
 in read path (#13427)

Fixes bug 475824752. Tracks the number of bytes received from the
transport layer and emits a warning log if GCS sends more bytes than
requested by the user during explicit range requests.

Subject: [PATCH 67/82] fix(bigquery-jdbc): avoid rollback on statement close
 in manual commit mode (#13503)

**Problem**

Manual commit mode does not work correctly because statement
cancellation triggers a transaction rollback.

**STR (Steps to Reproduce)**

1. Create a JDBC connection.
2. Disable auto-commit:

   ```java
   conn.setAutoCommit(false);
   ```
3. Execute a DML statement using a `PreparedStatement`.
4. Close the statement.
5. Call:

   ```java
   conn.commit();
   ```

**ER (Expected Result)**

* Closing a statement does not affect the active transaction.
* Pending changes remain available until an explicit `commit()` or
`rollback()` is performed on the connection.
* `conn.commit()` successfully persists transaction changes.

**AR (Actual Result)**

* Statement cleanup invokes `cancel()`.
* `cancel()` performs a transaction rollback.
* Pending transaction changes are discarded before `conn.commit()` is
called.
* `conn.commit()` has no effect because the transaction has already been
rolled back.

**Sample Java Code:**

```java
try (Connection conn = DriverManager.getConnection(jdbcUrl, props)) {
    conn.setAutoCommit(false);

    try (PreparedStatement ps =
             conn.prepareStatement(
                 "INSERT INTO test_table(id) VALUES (1)")) {
        ps.executeUpdate();
    } // statement cleanup invokes cancel() -> rollback

    conn.commit(); // nothing is committed
}
```

**Fix**

Remove transaction rollback from the statement cancellation path.
Transaction state is now managed exclusively through explicit
`Connection.commit()` and `Connection.rollback()` operations.

Subject: [PATCH 70/82] refactor(bigquery-jdbc): migrate metadata thread
 management to connection-scoped executor (#13556)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

b/520400589

This PR optimizes thread management for JDBC metadata methods,
implementing a deadlock-free, bipartite thread pool design and unifying
resource lifecycle management.

### Key Changes

* **Bipartite Thread Pool Architecture (Deadlock Prevention)**:
* Redirected all outer, orchestrating fetcher tasks (parent tasks) to
the connection’s cached query executor
(`connection.getExecutorService()`). Because the cached pool scales
dynamically as needed, this structurally prevents pool-induced deadlocks
(thread starvation).
* Kept all inner, highly concurrent parallel network API calls (child
tasks) on the connection's fixed-size metadata executor
(`connection.getMetadataExecutor()`). This bounds parallel network
traffic to prevent overwhelming the BigQuery backend.
* *Result*: The driver is fully protected against pool-induced
deadlocks, even under high concurrency or if `metadataFetchThreadCount`
is configured to `1`.

* **Connection-Scoped Shared Executor**:
* Migrated all asynchronous metadata operations (`getSchemas`,
`getTables`, `getColumns`, `getProcedures`, `getProcedureColumns`,
`getFunctions`, and `getFunctionColumns`) from spawning raw threads or
short-lived local pools to connection-managed executors.
* Configured the shared metadata pool to be lazily instantiated on
demand and gracefully shut down with the connection lifecycle. Idle
threads are automatically reclaimed after 60 seconds.

* **Lower CPU Overhead (Sequential Row-Building)**:
* Completely removed secondary CPU-bound thread pools (such as
`routineProcessorExecutor`, `processArgsExecutor`,
`tableProcessorExecutor`, and `processParamsExecutor`) previously used
for row-building.
* Refactored row-building and parameter-processing tasks to execute
sequentially on the background fetcher threads, removing
context-switching overhead and preventing nested-pool deadlock risks.

* **Teardown of Legacy Bridges**:
* Deleted the obsolete `wrapThread(Thread)` compatibility adapter in
`BigQueryDatabaseMetaData.java`.
* Removed obsolete `testWrapThread_*` cases from
`BigQueryDatabaseMetaDataTest.java`. Metadata queries now track and
cancel background tasks natively via standard `Future` handles.

* **Test Suite Refactoring**:
* Updated `BigQueryDatabaseMetaDataTest` setup to inject real,
connection-scoped cached executor services, ensuring that background
metadata tasks execute deterministically during testing.
* Added `@AfterEach` teardown logic to prevent test-suite thread leaks.
* Refactored argument-processing tests to verify row-building
synchronously without mock executors.

Subject: [PATCH 74/82] fix(spanner): pin inline read-write transactions to
 default endpoint (#13562)

Fixes location-aware routing for inline read-write transactions that
begin on the default endpoint.

When an inline read-write transaction (`TransactionSelector.BEGIN`)
starts on the default endpoint, the client must remember that default
endpoint affinity for the returned transaction ID. Without this, later
statements in the same transaction can be routed by CacheUpdate to a
direct endpoint, causing mid-transaction endpoint switches and ABORTED
failures.

This change records default endpoint affinity for inline read-write
begins, matching the existing behavior for explicit `BeginTransaction`
requests.

Subject: [PATCH 76/82] chore: rationalize SessionImpl field visibility

Document lock ownership before later steps remove the lock. Add @GuardedBy
to fields under the lock, move heartbeatInterval read into the synchronized
block in startRpc(), and comment fields intentionally read outside the lock.
No runtime change.

Subject: [PATCH 77/82] chore: migrate pool scheduling to a hashed-wheel timer

Replace ScheduledExecutorService with a BigtableTimer (Netty hashed wheel,
will move in-tree later) for heartbeat, deadline, watchdog, AFE-prune,
retry-create-session, and retry-delay. Owned by Client and shared across
pools.

Subject: [PATCH 78/82] chore: introduce VOperation as the head of the
 middleware chain

Replaces CancellableVRpc with a VOperation layer that sits above the VRpc
chain rather than inside it. VOperationImpl owns the gRPC Context
cancellation listener and constructs the per-op VRpcCallContext; downstream
middleware just sees the chain.

Subject: [PATCH 79/82] chore: introduce OpExecutor; plumb
 VRpcCallContext.getExecutor

VRpcCallContext.getExecutor() returns OpExecutor (thin wrapper with
runningThread affinity tracking). VOperationImpl constructs the per-call
SynchronizationContext + OpExecutor; RetryingVRpc drops its own SyncContext
and dispatches via ctx.getExecutor(). The uncaught-handler safety net moves
from RetryingVRpc up to VOperationImpl.

Subject: [PATCH 80/82] chore: move callback dispatch from RetryingVRpc to
 VRpcImpl

VRpcImpl.handle*() methods now dispatch listener callbacks via
ctx.getExecutor(), with CAS STARTED->CLOSED in all three (handleError no
longer proceeds from NEW) and decode moved into the executor task.
RetryingVRpc.Active drops its own wrap since callbacks already arrive on
the op executor. start() publishes ctx/listener only after winning the CAS
so a racing duplicate can't corrupt the winner's fields. SessionPoolImpl's
three direct listener.onClose paths also dispatch via ctx.getExecutor().

Subject: [PATCH 81/82] fix: arm heartbeat tick only while a vRPC is in flight

The pool-wide heartbeat monitor on main only inspected sessions in
inUseSessions (i.e. with an active vRPC). When heartbeat scheduling
moved into SessionImpl, the per-session timer was instead armed once on
ready and self-rescheduled indefinitely. The "no active vRPC" case
was reduced to a sentinel (nextHeartbeat = now + FUTURE_TIME), which
made checkHeartbeat no-op but kept the wheel ticking. It also left a
latent force-close on idle sessions: handleHeartBeatResponse
unconditionally resets nextHeartbeat to now + heartbeatInterval, so an
idle session that received a server heartbeat became eligible for
force-close on the next missed beat.

Tie the timer to the vRPC lifecycle to match main's semantic:

- handleOpenSessionResponse no longer schedules the tick.
- startRpc arms the tick after setting nextHeartbeat.
- handleVRpcResponse / handleVRpcErrorResponse cancel the tick.
- updateState (already cancels on transition past READY).

Add SessionImplTest coverage with a counting BigtableTimer wrapper that
asserts (a) no schedule before any vRPC and (b) exactly one
schedule/cancel per vRPC lifecycle.
