 ## Limitations {#limitations}
 
 - [`DEFAULT`](/sql-reference/statements/create/table#default) is not supported.
-- Individual messages are limited to 2MB (uncompressed) by default when running with the smallest (XS) replica size, and 8MB (uncompressed) with larger replicas.  Messages that exceed this limit will be rejected with an error.  If you have a need for larger messages, please contact support.
+- Individual messages are limited to 16MB (uncompressed) by default when running with the smallest (XS) replica size, and 32MB (uncompressed) with larger replicas.  Messages that exceed this limit will be rejected with an error.  If you have a need for larger messages, please contact support.
 
 ## Delivery semantics {#delivery-semantics}
 ClickPipes for Kafka provides `at-least-once` delivery semantics (as one of the most commonly used approaches). We'd love to hear your feedback on delivery semantics [contact form](https://clickhouse.com/company/contact?loc=clickpipes). If you need exactly-once semantics, we recommend using our official [`clickhouse-kafka-connect`](https://clickhouse.com/blog/real-time-event-streaming-with-kafka-connect-confluent-cloud-clickhouse) sink.

 - Pub/Sub subscription filters are immutable — changing the filter expression requires recreating the pipe.
 - Filters apply to message attributes only, not the message payload.
