Duplicate copies drifted apart: smoke_datagen only knew int64 and string; smoke_relationship renamed builders to avoid same-name collisions; smoke_stage_d had a 12-arm version of streamDrawExpr. The result was noisy, and introducing a new StreamDraw arm meant updating two unrelated files to stay consistent. Consolidates into test/integration/helpers.go: - litOf widened to accept int / int64 / float64 / string / bool. - streamDrawExpr handles all twelve StreamDraw arms in one place. - streamDrawAttr / chooseAttr wrap it for the common Attr shape. - drainRuntime + new drainSpec + copyRowsTo + loadSpec replace per-file drain* / copy* variants (callers keep thin table-specific wrappers where the table name is load-bearing). - relAttr / rowIndexKind / lookupOf / daysEpoch / litFloat promoted.

Fills in the TPC-H row of the matrix (pg/mysql/pico/ydb × tpcb/tpcc/tpch). Why these edits: - mysql.sql: DECIMAL(12,2) currency, DATE dates, DATE_ADD/SUB for interval math; q17 and q20 rewritten with derived-table joins to avoid O(N·M) correlated-subquery plans. MySQL 8-only. - pico.sql: VARCHAR in place of CHAR, DATETIME for dates. sbroad rejects UPDATE-with-correlated-subquery and UPDATE ... FROM, so finalize_totals is a noop; o_totalprice stays at the placeholder zero. Every query (q1..q22) still executes. - ydb.sql: Int64 / Double / Utf8 / Timestamp schema; cross-joins replace comma-joins; correlated subqueries decorrelated into named $subqueries. Q15/17/20 lift their thresholds via YQL named subqueries. Finalize_totals uses UPDATE ON with a pre- aggregated per-orderkey subquery. tx.ts wiring: - Dialect-aware SQL_FILE dispatch (postgres/mysql/picodata/ydb). - NEEDS_END_DATES branch precomputes :date_1m / :date_3m / :date_1y for picodata and ydb (no date + interval 'N month' on those dialects); pg/mysql compute it in-SQL. - litDouble() helper for the zero-init o_totalprice placeholder (mirrors the tpcc fix so YDB's Double column accepts the lit). - nationRegionKeyExpr() replaces the string-dict lookup with an Expr.if cascade so n_regionkey lands as int64 on YDB. - runSection() guards empty SQL sections so non-pg dialects can omit set_logged cleanly. - tpchRetailPrice() forces Double on the divisor to keep p_retailprice float across all dialects. Integration tests: - TestTpchLoadOnMySQL / OnPicodata / OnYDB under build tag `integration`, gated via STROPPY_SKIP_INTEGRATION=1. Each runs SF=0.01 end-to-end, validates row counts, FK integrity (skipped for YDB, decorrelated for picodata), and all 22 queries green per the `--steps queries` log markers.

First, Expr.lit(100.0) collapses to int64 because JS's Number.isInteger(100.0) is true; drivers with strict typing (YDB BulkUpsert on Double columns) rejected the int64-shaped literal, forcing inline litDouble helpers in multiple workloads. Expr.litFloat forces the double oneof arm unconditionally so workloads can be explicit about currency / decimal intent. Second, Dict.values stringifies every entry because DictRow.values is repeated string on the wire (dstparse emits JSON that preserves string shape even for numerically-weighted columns, e.g. tpch n_regionkey). Workarounds like a 25-branch Expr.if cascade over rowIndex are ugly and O(N) per row. std.parseInt / std.parseFloat are the minimal, composable bridge: the workload stays declarative (Attr.dictAtInt(dict, idx)), the wire is unchanged, no proto break. We explicitly called out in plan §5.6 that we dropped parse_int/parse_float earlier; bringing them back is the honest fix, since JSON-encoded upstream data really is string-typed. Stdlib grows by exactly the two parsers; both reject empty input and unparseable strings via ErrBadArg. TS surface adds Expr.litFloat, two std wrappers, and two Attr shortcuts. --- internal/static/datagen.ts | 50 +++++++++++ internal/static/tests/datagen.test.ts | 26 ++++++ pkg/datagen/stdlib/parse.go | 63 ++++++++++++++ pkg/datagen/stdlib/parse_test.go | 120 ++++++++++++++++++++++++++ pkg/datagen/stdlib/stdlib_test.go | 4 +- 5 files changed, 262 insertions(+), 1 deletion(-) create mode 100644 pkg/datagen/stdlib/parse.go create mode 100644 pkg/datagen/stdlib/parse_test.go diff --git a/internal/static/datagen.ts b/internal/static/datagen.ts index 62d07c04..80515b5e 100644 --- a/internal/static/datagen.ts +++ b/internal/static/datagen.ts @@ -207,6 +207,20 @@ export const Expr = { throw new Error(`datagen: Expr.lit: unsupported type ${typeof x}`); }, + /** + * Typed double literal — always emits the `double` oneof arm, even when + * `x` is integer-valued.

From 17b087ddd422a1d948e115d9fb7cd8b9e6e70875 Mon Sep 17 00:00:00 2001 From: Nikita Aleksandrov Date: Thu, 23 Apr 2026 00:15:42 +0300 Subject: [PATCH 46/89] feat(datagen): add Expr.litNull and Literal.null arm MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Deterministic SQL NULL literals for Expr.if branches. TPC-C §4.3.3.1 requires NULL for o_carrier_id when o_id is in [2101, 3000] and for ol_delivery_d on undelivered rows; the existing per-attr Null.rate policy is stochastic and does not cover the deterministic branch case. The new Literal.null arm points at a NullMarker (zero-field message used as a typeless oneof payload) and evaluates to Go nil, which flows through the row scratch and pgx.CopyFromSource unmodified. Covered by a tmpfs-PG integration test that asserts the boundary row counts and IS NULL / = 'value' spot checks. --- docs/proto.md | 14 + internal/static/datagen.ts | 10 + internal/static/stroppy.pb.js | 4 +- internal/static/stroppy.pb.ts | 91 ++- internal/static/tests/datagen.test.ts | 26 + .../proto/stroppy/version.stroppy.pb.go | 2 +- pkg/datagen/dgproto/datagen.pb.go | 566 ++++++++++-------- pkg/datagen/dgproto/datagen.pb.validate.go | 141 +++++ pkg/datagen/expr/if_test.go | 43 ++ pkg/datagen/expr/literal.go | 6 + pkg/datagen/expr/literal_test.go | 17 + proto/stroppy/datagen.proto | 9 + test/integration/smoke_datagen_test.go | 104 ++++ 13 files changed, 767 insertions(+), 266 deletions(-) diff --git a/docs/proto.md b/docs/proto.md index 19407c3f..fd16e0df 100644 --- a/docs/proto.md +++ b/docs/proto.md @@ -103,6 +103,7 @@ - [Lookup](#stroppy-datagen-Lookup) - [LookupPop](#stroppy-datagen-LookupPop) - [Null](#stroppy-datagen-Null) + - [NullMarker](#stroppy-datagen-NullMarker) - [Parallelism](#stroppy-datagen-Parallelism) - [Population](#stroppy-datagen-Population) - [RelSource](#stroppy-datagen-RelSource) @@ -1705,6 +1706,7 @@ Literal is a single typed scalar constant. | bool | [bool](#bool) | | Boolean literal. | | bytes | [bytes](#bytes) | | Raw bytes literal. | | timestamp | [google.protobuf.Timestamp](#google-protobuf-Timestamp) | | Timestamp literal used for date and datetime columns. | +| null | [NullMarker](#stroppy-datagen-NullMarker) | | Explicit SQL NULL literal.

Required by TPC-C §4.3.3.1, which mandates that each district's o_c_id column contain every customer id in [1, 3000] exactly once in a shuffled order; per-district permuteIndex(districtSeed, row, 3000) satisfies the spec without materializing the schedule. Implemented as a 4-round balanced Feistel cipher (SplitMix64 round function) with cycle-walking to cover non-power-of-two domain sizes. No per-call state — parallel workers can call this freely for disjoint idx ranges. Covered by bijection, determinism, independence, n=1, 2^k+1 worst-case, and argument-validation unit tests. --- internal/static/datagen.ts | 17 ++ internal/static/tests/datagen.test.ts | 6 + pkg/datagen/stdlib/permute.go | 164 ++++++++++++++++++ pkg/datagen/stdlib/permute_test.go | 235 ++++++++++++++++++++++++++ pkg/datagen/stdlib/stdlib_test.go | 3 +- 5 files changed, 424 insertions(+), 1 deletion(-) create mode 100644 pkg/datagen/stdlib/permute.go create mode 100644 pkg/datagen/stdlib/permute_test.go diff --git a/internal/static/datagen.ts b/internal/static/datagen.ts index ba2a1580..273491f5 100644 --- a/internal/static/datagen.ts +++ b/internal/static/datagen.ts @@ -376,6 +376,23 @@ export const std = { parseFloat(x: PbExpr): PbExpr { return call("std.parseFloat", [x]); }, + + /** + * Deterministic bijection of [0, n) keyed by `seed`.

Only o_ol_cnt stays at a fixed 10 (spec wants Uniform 5..15); deferred per plan §16 since variable-degree child populations need Relationship composition and CC4 still holds. YDB BulkUpsert rejected `void_type: NULL_VALUE` for the new NULL cells, so pkg/driver/ydb/insert_spec.go now buffers each batch, infers per- column types from the first non-nil cell, and emits typed `types.NullValue(colType)` + `types.OptionalValue` wrappers only on columns that actually carry NULLs in the batch. Columns never nil keep their historical bare-value shape so NOT NULL primary keys still work. Integration test adds spec-compliance assertions (o_carrier_id split, o_c_id permutation, ORIGINAL-marker rate band, delivered ol_amount = 0) and tightens c_last shape to the syllable alphabet. --- pkg/driver/ydb/insert_spec.go | 177 +++++++++++- test/integration/tpcc_workload_test.go | 125 ++++++++- workloads/tpcc/tpcc_helpers.ts | 102 +++++++ workloads/tpcc/tx.ts | 371 +++++++++++++++++++++---- 4 files changed, 687 insertions(+), 88 deletions(-) create mode 100644 workloads/tpcc/tpcc_helpers.ts diff --git a/pkg/driver/ydb/insert_spec.go b/pkg/driver/ydb/insert_spec.go index 4a1f9251..53e3dcfc 100644 --- a/pkg/driver/ydb/insert_spec.go +++ b/pkg/driver/ydb/insert_spec.go @@ -113,6 +113,15 @@ func (d *Driver) runChunk( // otherwise exactly limit rows are emitted.

Sobek binds Sample/Next/Seek/Reset by reflection on the returned pointer, so the hot path hits the matching kernel directly without a per-call oneof switch, expr.Eval dispatch, or *rand.Rand allocation. Optimisations applied: direct arm dispatch at construction (a), unboxed literal bounds (b), pooled *rand.Rand re-seeded in place through the new seed.SeedPCG helper (c), eager handle resolution (e). Optimisation (d), cached seed prefix, is intentionally absent — the seed package exposes only Derive as the single composition, and bifurcating that surface violates CLAUDE.md §6. The equivalence test under pkg/datagen/expr proves iter-2's seed composition bit-matches evalContext.Draw at (streamID=0, attrPath="draw", rowIdx=key), and that the pooled PCG re-seed produces the same stream as seed.PRNG on a fresh one. xk6air-level unit tests are not possible because the package imports internal/common, which blocks go test at the module boundary; the JS surface is covered by the bench_gen2 workload added in a follow-up commit. --- cmd/xk6air/draw.go | 204 +++++++++++++ cmd/xk6air/draw_arms.go | 353 ++++++++++++++++++++++ cmd/xk6air/draw_ctors.go | 194 ++++++++++++ cmd/xk6air/draw_prng_pool.go | 44 +++ cmd/xk6air/instance.go | 22 ++ pkg/datagen/expr/draw_equivalence_test.go | 161 ++++++++++ pkg/datagen/expr/kernels.go | 175 +++++++++++ pkg/datagen/seed/seed.go | 10 + pkg/datagen/seed/seed_test.go | 21 ++ 9 files changed, 1184 insertions(+) create mode 100644 cmd/xk6air/draw.go create mode 100644 cmd/xk6air/draw_arms.go create mode 100644 cmd/xk6air/draw_ctors.go create mode 100644 cmd/xk6air/draw_prng_pool.go create mode 100644 pkg/datagen/expr/draw_equivalence_test.go diff --git a/cmd/xk6air/draw.go b/cmd/xk6air/draw.go new file mode 100644 index 00000000..8d61de61 --- /dev/null +++ b/cmd/xk6air/draw.go @@ -0,0 +1,204 @@ +// Package xk6air draw.go — module-scoped registries for the tx-time +// Draw path (iter 2).

The returned SampleableDraw has the 4-method shape (sample/next/seek/reset) that matches the Drawer interface in cmd/xk6air. Non-literal bounds are rejected at the coercion layer — workload authors can still use Expr.lit(n) by habit, but row-index / col-ref bounds now fail fast rather than silently marshaling a junk number. The k6/x/stroppy module is resolved lazily through a require so vitest tests can stub it via __setDrawRTStroppyModule; the test file drawrt.test.ts exercises determinism, Seek+Next equivalence, Reset, and the coercion error path with a synthetic stub. --- internal/static/datagen.ts | 336 +++++++++++++++++++++++++++ internal/static/stroppy.d.ts | 82 +++++++ internal/static/tests/drawrt.test.ts | 156 +++++++++++++ 3 files changed, 574 insertions(+) create mode 100644 internal/static/tests/drawrt.test.ts diff --git a/internal/static/datagen.ts b/internal/static/datagen.ts index 273491f5..ddb608da 100644 --- a/internal/static/datagen.ts +++ b/internal/static/datagen.ts @@ -1522,6 +1522,342 @@ function coerceExpr(v: PbExpr | number | bigint): PbExpr { export type NullSpec = PbNull; +// -------- Namespace: DrawRT (tx-time draw, iter 2) -------- + +/** + * SampleableDraw is the JS-visible surface returned by every DrawRT.xxx + * builder.

charset=UTF-8 Content-Transfer-Encoding: 8bit Rewrites both procs.ts variants so their load phase uses driver.insertSpec(Rel.table(...)) with schemas identical to the sibling tx.ts (same seeds, same layout). The tx phase now uses DrawRT for all per-VU randomness with the same seedOf helper adopted in step 3/4. tpcc/procs.ts carries the validate_population step (CC1-CC4 + §4.3.4 cardinalities + §4.3.3.1 distribution rules) and the stored-proc dispatch via NewPicker.

Updates the sole external caller (cmd/xk6air/pick.go) to the new import. With no external callers left, deletes pkg/common/generate wholesale (~3k LOC: value.go, utils.go, dictionary.go, inject.go, the constraint/distribution/primitive/randstr subtrees, plus their tests). go mod tidy drops the no-longer-needed transitive deps. --- cmd/xk6air/pick.go | 10 +- pkg/common/generate/bench_test.go | 111 ---- pkg/common/generate/constraint/types.go | 5 -

Deletes InsertDescriptor, InsertMethod enum, QueryParamDescriptor, and QueryParamGroup from descriptor.proto; TxIsolationLevel stays. Scrubs the DriverQuery.method field and DriverConfig.default_insert_method field that depended on the removed InsertMethod / defaultInsertMethod surface. Regenerates Go + TS sources via make proto. proto/ts_bundle/build.js drops the LegacyInsertMethod collision alias — the name was only needed while stroppy.InsertMethod and stroppy.datagen.InsertMethod coexisted.

But the new stroppy.datagen.InsertMethod enum in datagen.proto carries the same NATIVE/PLAIN_BULK/PLAIN_QUERY values, and every driver implements all three insert paths per the handoff driver surface table. The knob is legitimate — it pins every InsertSpec's method so cross-DB runs can compare raw insert throughput on identical protocols. Re-adds InsertMethodName / insertMethodMap / DriverSetup.defaultInsertMethod pointed at the new enum.

Each worker drains its cloned Runtime and +discards rows; there is no I/O to arbitrate. This is mechanically simple +but lands in Stage I alongside the registry redesign (Gap 2) because +fixing noop first would immediately surface Gap 2 at higher concurrency. + +### Bonus observation + +The loader wiring audit noted in plan §4.1 still holds: +`pkg/datagen/loader/loader.go` exposes `Loader` / `MaxWorkersFromEnv` but +no production driver imports them. `STROPPY_MAX_LOAD_WORKERS` is inert. +Stage I should either wire the loader into the driver dispatch path, or +delete the unused symbols and document that per-spec `parallelism.workers` +is the single dial. + +--- + +## Gap 2 — `LookupRegistry` is not safe for concurrent `Clone()` consumers [CLOSED c11b087] + +Severity: **critical (memory-safety / correctness)**. + +### Observation + +`pkg/datagen/lookup/lookup.go:83-84` states: *"Reads are not thread-safe; +the runtime serializes them per worker."* The implementation lives up to +this claim — the registry carries an `inFlight map[string]struct{}`, a +per-pop `rowCache` (`map[int64]*list.Element` + `container/list`), and a +`dicts` map. None are guarded. + +But `pkg/datagen/runtime/flat.go#Clone` (line 207) copies `registry` by +reference into every clone: + + ctx: &evalContext{ + ... + registry: r.ctx.registry, // shared! + ... + } + +So `common.RunParallel` hands all workers clones whose `ctx.registry` +points at the *same* `*LookupRegistry`. Whenever a worker's Lookup +misses the LRU, it writes into the shared map while siblings may be +reading or evicting. Go's runtime detects this at `map.Delete` / +`mapaccess2` and aborts with `fatal error: concurrent map writes`. + +### Reproduction + +`tpch` SF=0.1 against postgres at workers=4 and workers=8 crashes roughly +half the time. The lineitem spec evaluates +`Attr.lookup("orders", "o_orderkey", ...)` and similar into its +`ordersLookup` / `partLookup` LookupPops from every parallel chunk, so +the race surfaces quickly once workers ≥ 4.

Workers ≥ 4 with the cache thrashing against 600 K live entities +tips it over. + +### Why noop didn't crash + +See Gap 1 — noop is currently single-threaded, so Clone is never called +on any tpch run. + +### Design options for Stage I + +Three candidates, roughly ordered by cost vs. upside. + +1. **Per-clone registry.** Add a `CloneRegistry()` method that + deep-copies the pops (shared DAG, fresh `rowCache` and `inFlight` + per clone). Each worker gets independent cache state. Cost: caches + no longer share across workers, so hit rate halves when `workers = + 2` (and so on). Simplest to implement. + +2. **Shared, sharded registry.** Partition by `popName`: reads of + population X go through a sync.RWMutex protecting *only* X's cache. + Keeps hit rate, adds coarse serialization per pop. Risk: mutex + contention on the hot `orders` pop becomes the new bottleneck. + +3. **Lock-free read path + write batching.** `sync/atomic.Pointer` to + an immutable snapshot of `rowCache` per pop; misses take a write + path that copies-on-write. Best throughput, most code. Overkill + unless the sharded approach shows measurable contention. + +Stage I should start with option 1 (per-clone registry) — it eliminates +the safety bug, preserves all existing tests, and the cache-hit regression +is bounded (and can be measured to decide whether options 2/3 are worth +the work). + +### Tests to add after the fix + +- `pkg/datagen/lookup/lookup_concurrent_test.go` — race-detector + (`go test -race`) hammering `Get` concurrently at 8 workers. +- `pkg/driver/postgres/insert_spec_test.go` extension — `-race` run + of a tpch-lineitem-shaped spec at workers ∈ {1, 4, 16}. +- Integration test `test/integration/tpch_test.go` that loops tpch + SF=0.1 load 10× at workers=8 under `-race` and asserts all succeed. + +--- + +## Summary + +| Gap | Component | Severity | Scope | +| --- | --------------------------------- | -------- | ---------- | +| 1 | noop driver InsertSpec fan-out | high | ~30 LOC | +| 2 | LookupRegistry clone + LRU share | critical | design | + +Gap 1 without Gap 2 would turn every tpch (and any future DS) load path +into a race-bug.

Its data +generator produces deterministic, seekable rows for a set of tables +declared in TypeScript; a workload author writes schemas, not row +loops. The framework compiles those schemas into a proto wire message, +hands it to a Go evaluator, and streams rows into any supported driver +(postgres, mysql, picodata, ydb, csv, noop). + +The generator replaces per-row iterators with pure functions: every +emitted value is a function of the root seed, the attribute path, and +the row index. That is enough to make the load path seekable — any +worker can start at any row with no warm-up — and deterministic — +rerunning a spec with the same seed reproduces rows byte-for-byte. + +### Who it is for + +- Benchmark owners who need TPC-style workloads on a new DB dialect. +- DB vendors validating their SQL surface against a spec-shaped load. +- QA engineers writing reproducible load scenarios for perf regression + tracking. + +### What problem it solves + +Compared to `dbgen`/`dsdgen` (one binary per spec), go-tpc (Go-only, +tightly coupled to the spec), or bespoke fixtures, stroppy separates +**schema** (TS) from **evaluator** (Go) from **driver** (per-DB).

Core concepts + +### 3.1 `Rel.table` + +The single entry point for declaring a loadable table. Every option +is commented in `internal/static/datagen.ts` under `RelTableOpts`. + +```ts +Rel.table("table_name", { + size: N, // Int64Like; Population.size on the wire. + seed: SEED, // uint64 root seed; 0 picks random per run. + method: DatagenInsertMethod.NATIVE, // PLAIN_QUERY | PLAIN_BULK | NATIVE. + parallelism: LOAD_WORKERS || undefined, // hint; see docs/parallelism.md. + attrs: { col: exprForCol, ... }, + columnOrder?: ["col", ...], // defaults to Object.keys(attrs) plus SCD-2. + + // advanced (§6): + relationships?: [Rel.relationship(...)], + iter?: "rel-name", + lookupPops?: [Rel.lookupPop(...)], + cohorts?: [Rel.cohort(...)], + scd2?: Rel.scd2(...), + + dicts?: { keyOverride: PbDict, ... }, +}); +``` + +- `size` — row count for the population. The runtime iterates + `[0, size)`. In relationship mode the per-entity degree overrides + this. +- `seed` — all per-row PRNGs seed from `Derive(seed, ...)`. Pin a + distinct constant per table so streams across tables stay + independent. +- `method` — wire protocol hint. Drivers may ignore or downgrade + (mysql has no `COPY`, so `NATIVE` falls back to `PLAIN_BULK`). +- `parallelism.workers` — see `docs/parallelism.md`. Default is 1. +- `attrs` — insertion order becomes the default emission order. Use + `columnOrder` to override. +- `dicts` — rarely needed; inline `Dict.*` usage auto-registers. Set + this only when a dict's opaque key is already known (regenerated + JSON pipelines). + +### 3.2 `Attr.*` helpers + +Attribute-level builders. Each returns an `Expr` that goes into +`Rel.table({ attrs })`. + +| Helper | Shape | Purpose | +|---|---|---| +| `Attr.rowIndex(kind?)` | int64 | 0-based row counter. `kind` picks ENTITY / LINE / GLOBAL; default ENTITY (= population row in flat mode). | +| `Attr.rowId()` | int64 | 1-based convenience = `rowIndex() + 1`. | +| `Attr.dictAt(dict, idx, col?)` | string | Row read from a dict at a computed index. | +| `Attr.dictAtInt(dict, idx, col?)` | int64 | `std.parseInt(dictAt(...))`. | +| `Attr.dictAtFloat(dict, idx, col?)` | float64 | `std.parseFloat(dictAt(...))`. | +| `Attr.lookup(popName, attr, entityIdx)` | value | Cross-population read. | +| `Attr.blockRef(slot)` | value | Read a Relationship Side's named block slot. | +| `Attr.cohortDraw(name, slot, bucketKey?)` | int64 | Entity id from a named cohort. | +| `Attr.cohortLive(name, bucketKey?)` | int64 | 1 if the cohort bucket is active, else 0. | + +Examples: + +```ts +// 1-based id; type int64 on the wire. +id: Attr.rowId(), + +// Dict read indexed by row. +n_name: Attr.dictAt(nationsNameDict, Attr.rowIndex()), + +// Dict read coerced to int64 — dstparse emits all values as strings. +n_regionkey: Attr.dictAtInt(nationRegionKeyDict, Attr.rowIndex()), +``` + +### 3.3 `Expr.*` composition + +The closed grammar the evaluator supports. Every arm maps to a +`Expr.kind.oneofKind` in `datagen.proto`. Builders hide the oneof +boilerplate; you compose from these alone. + +| Arm | Builder | Notes | +|---|---|---| +| Literal int64 | `Expr.lit(n)` | Integer `number` or `bigint`. | +| Literal double | `Expr.litFloat(x)` | Forces `double` even when `Number.isInteger(x)` (e.g. `0.0`). | +| Literal string | `Expr.lit("s")` | | +| Literal bool | `Expr.lit(true)` | | +| Literal date | `Expr.lit(new Date(...))` | Converts to int64 epoch-days. | +| Explicit NULL | `Expr.litNull()` | Emits Go `nil`; drivers render as SQL NULL. Use inside `Expr.if` branches. | +| Column ref | `Expr.col("name")` | Reads a sibling attr in the same row scope. Declaration-order dependency. | +| Row index | `Attr.rowIndex(kind?)` | Available as `Attr.rowIndex` (no separate Expr.* helper). | +| Ternary | `Expr.if(cond, then, else_)` | Lazy — only the selected branch evaluates. | +| Arithmetic | `Expr.add/sub/mul/div/mod` | | +| Concat | `Expr.concat(a, b)` | Strings. | +| Comparison | `Expr.eq/ne/lt/le/gt/ge` | | +| Logical | `Expr.and/or/not` | | +| Stdlib call | `std.format(...)` etc. | See §7. Low-level `std.call(name, ...args)` is the escape hatch. | +| Dict read | `Attr.dictAt(dict, idx, col?)` | Mirrors the Attr helper. | +| Block slot | `Expr.blockRef(slot)` | Read a relationship-side block. | +| Lookup | `Attr.lookup(popName, attr, idx)` | Cross-population read. | +| Stream draw | `Draw.intUniform(...)` etc. | §4. | +| Choose | `Expr.choose([{weight, expr}, ...])` | Weighted branch picker. | +| Cohort | `Attr.cohortDraw/cohortLive` | §6.2. | + +Common gotchas: + +- `Expr.lit(0.0)` collapses to int64 because `Number.isInteger(0.0)` + is true in JS. YDB's `Double` columns reject int64; use + `Expr.litFloat(0.0)`. +- `Expr.if(cond, a, b)` evaluates lazily. `b` must type-match `a`; + use `Expr.litNull()` when one branch must be NULL. +- `Expr.col(name)` reads the current row's scratch map. The + referenced attr must appear **earlier** in `Rel.table.attrs` + insertion order; the compile-time DAG check rejects cycles. + +### 3.4 Seed and determinism + +The root seed flows from `Rel.table({ seed })` → `InsertSpec.seed` → +`runtime.NewRuntime(spec)` → `evalContext.rootSeed`. Every PRNG in the +generator — stream draws, null decisions, cohort schedules, lookup +caches — derives its key from `seed.Derive(rootSeed, path...)` with a +path that includes the attr name, the stream id, and the row index. + +Guarantees: + +- Same spec + same seed → same row multiset. +- Same row index → same value, independent of how the row range is + partitioned across workers. +- `seed: 0` picks a fresh seed per run (via the xk6 entry point); pin + a nonzero constant for reproducible output. + +Counter-example — **do not**: + +- Mutate state across Expr calls (the evaluator is stateless; scratch + lives only for one row). +- Seed a PRNG from `Date.now()` in TS (breaks the wire-level seed + contract). + +--- + +## 4. `Draw.*` — stream draws + +Stream draws are seeded per row. Each builder wraps a `StreamDraw` +oneof with `stream_id=0`; `compile.AssignStreamIDs` populates the id +at `runtime.NewRuntime` so independent draws in the same attr stay +independent. + +### 4.1 `Draw.intUniform` + +```ts +Draw.intUniform({ min: Expr.lit(1), max: Expr.lit(50) }) +``` + +Uniform integer on `[min, max]` inclusive. Bounds are `Expr`, so they +can depend on `Attr.rowIndex()` or an earlier `Expr.col(...)`. Used +in TPC-H `p_size` (1..50), `o_custkey` (1..N_CUSTOMER), the per-line +date offsets `L_SHIPDATE_OFF_*`, and every other straight uniform +draw in the spec. + +Output: int64. Per-call cost: one `seed.Derive` + one modular +reduction. At ~67 ns/call the Derive call dominates; on hot paths +prefer DrawRT (see §8). + +### 4.2 `Draw.floatUniform` + +```ts +Draw.floatUniform({ min: Expr.lit(0.0), max: Expr.lit(1.0) }) +``` + +Uniform float on `[min, max)`. Output type double. + +### 4.3 `Draw.normal` + +```ts +Draw.normal({ min: Expr.lit(0), max: Expr.lit(1000), screw: 3.0 }) +``` + +Truncated normal clamped to `[min, max]`. Mean `(min+max)/2`, stddev +`(max-min)/(2*screw)`. `screw=0` defaults to `3.0`. + +### 4.4 `Draw.zipf` + +```ts +Draw.zipf({ min: Expr.lit(1), max: Expr.lit(1000), exponent: 1.1 }) +``` + +Zipfian integer on `[min, max]`. Exponent at or below 1 is internally +nudged. + +### 4.5 `Draw.nurand` + +```ts +Draw.nurand({ a: 1023, x: 1, y: 3000, cSalt: 0xC1A57 }) +``` + +TPC-C §2.1.6 `NURand(A, x, y)` — non-uniform skew toward a random +fixed value. The formula is `((rand(0, A) | rand(x, y)) + C) mod (y +- x + 1) + x`, producing a distribution with a heavy-tailed bias +that matches TPC-C's customer-id and item-id access patterns. + +`cSalt` selects the per-stream constant C via `splitmix64(salt)`; +pass `0` for the deterministic default. The spec requires distinct +C across (customer, item, last-name) streams within one run — use +distinct non-zero salts. + +Typical bindings: + +- `NURand(1023, 1, 3000)` — customer id +- `NURand(8191, 1, 100000)` — item id +- `NURand(255, 0, 999)` — last-name dict index + +### 4.6 `Draw.bernoulli` + +```ts +Draw.bernoulli({ p: 0.1 }) +``` + +Returns int64 `1` with probability `p`, else `0`. To branch on the +result, lift with `Expr.eq`: + +```ts +Expr.if(Expr.eq(Draw.bernoulli({ p: 0.1 }), Expr.lit(1)), + Expr.lit("RARE"), + Expr.lit("COMMON")) +``` + +### 4.7 `Draw.date` + +```ts +Draw.date({ minDate: new Date("1992-01-01"), + maxDate: new Date("1998-12-31") }) +``` + +Uniform date on the inclusive range. Bounds convert to int64 epoch +days on the wire; the evaluator emits a `time.Time` scalar. + +### 4.8 `Draw.decimal` + +```ts +Draw.decimal({ min: Expr.lit(-999.99), max: Expr.lit(9999.99), scale: 2 }) +``` + +Uniform float on `[min, max]`, rounded to `scale` fractional digits. +Returns float64; downstream drivers round-trip it through their +`DECIMAL`/`NUMERIC` binding. + +### 4.9 `Draw.ascii` + +```ts +Draw.ascii({ + min: Expr.lit(25), max: Expr.lit(40), + alphabet: Alphabet.enNumSpc, +}) +``` + +Random ASCII string. Length drawn uniformly from `[min, max]`; +characters drawn from `alphabet` — a list of `AsciiRange` items. The +predefined `Alphabet.*` constants (`en`, `enNum`, `num`, `enUpper`, +`enSpc`, `enNumSpc`, `ascii`) cover the common cases. + +### 4.10 `Draw.dict` + +```ts +Draw.dict(containerDict) // uniform +Draw.dict(mktSegmentDict, { weightSet: "" }) // default weighted set +``` + +Uniform or weighted pick from a scalar dict. Without `weightSet`, and +when the dict carries no weights, the draw is uniform. + +### 4.11 `Draw.joint` + +```ts +Draw.joint(regionNationDict, "nation_name") +``` + +Tuple draw from a multi-column dict, returning one column of the +chosen tuple. Pair several joint draws with the same `tupleScope` to +return multiple columns of the same row (reserved for future spec +parity; D1 treats each joint as independent). + +### 4.12 `Draw.phrase` + +```ts +Draw.phrase({ + vocab: colorsDict, + minWords: Expr.lit(5), maxWords: Expr.lit(5), + separator: " ", +}) +``` + +Space-joined word sequence drawn uniformly from a vocabulary dict. +Used in TPC-H for `p_name` (five colors). + +### 4.13 `Draw.grammar` + +```ts +Draw.grammar({ + rootDict: grammarDict, + phrases: { N: npDict, V: vpDict }, + leaves: { N: nounsDict, V: verbsDict, J: adjectivesDict }, + maxLen: Expr.lit(115), + minLen: Expr.lit(31), // re-walks up to 8 times if too short +}) +``` + +Two-phase template walker (TPC-H §4.2.2.14). Picks a sentence from +`rootDict`; each uppercase-letter token either expands a phrase +template (one level deep) or emits a leaf word. Truncates to `maxLen` +characters; re-walks up to 8 times when `minLen` is set. + +Walk shape, taken from TPC-H's comment generation: + +- Root dict row: `"N V J N"` — a template with noun/verb/adj/noun + placeholders. +- `phrases["N"]`: rows like `"N"`, `"J N"`, `"J, J N"` — a noun + phrase can expand into another template before resolving to leaves. +- `leaves["N"]`: rows like `"accounts"`, `"requests"`, `"packages"`. + +At evaluation the walker picks a template, tokenizes it, and for each +uppercase-letter token picks either a phrase (once, then tokenizes +the result) or a leaf word. Literal tokens (lowercase words, +punctuation, whitespace) pass through unchanged. + +The two-phase bound (phrases may not recurse) is a spec invariant, +not an implementation limit. It keeps walks bounded in the worst +case even for adversarial dict contents. + +--- + +## 5. `Dict.*` — dictionary builders + +Dicts carry reference data: scalar value lists, value+weight lists, +multi-column tuples, named weight profiles. Dicts are deduplicated by +content hash and referenced by opaque string keys. + +| Builder | Purpose | +|---|---| +| `Dict.values([v0, v1, ...])` | Scalar dict, uniform weights. | +| `Dict.weighted(values, weights)` | Scalar dict, single default weight profile. | +| `Dict.multiWeighted(values, { profileA: [...], profileB: [...] })` | Scalar dict with named weight profiles; selected via `Draw.dict(d, { weightSet: "profileA" })`. | +| `Dict.joint(columns, rows)` | Multi-column dict; weights per row optional (all-or-nothing). | +| `Dict.jointWeighted(columns, profileNames, rows)` | Multi-column dict with N named weight profiles. | +| `Dict.fromJson(payload)` | Coerce the canonical `cmd/dstparse` JSON shape into a PbDict. | + +Example — inline weighted scalar: + +```ts +const orderPriorityDict = Dict.weighted( + ["1-URGENT", "2-HIGH", "3-MEDIUM", "4-NOT SPECIFIED", "5-LOW"], + [20, 40, 40, 40, 20], +); +``` + +Example — build from dstparse JSON: + +```ts +function scalarDictFromJson(name: string): DictBody { + const d = distributions.distributions[name]; + if (!d || d.rows.length === 0) return Dict.values([""]); + return Dict.values(d.rows.map((r) => String(r.values[0]))); +} +``` + +A dict referenced anywhere inside `Rel.table`'s attrs, lookup pops, +relationship block slots, cohort bucket keys, or SCD-2 branches is +automatically emitted under `InsertSpec.dicts`. No explicit +registration needed. + +--- + +## 6. Relational structures + +The four primitives that reach across populations. + +### 6.1 `Rel.relationship` (parent-child) + +A Relationship binds two populations into a joint iteration space. The +child-side iteration is driven by the parent's row range, scaled by a +per-parent `Degree`. + +Signature: + +```ts +Rel.relationship(name, [ + Rel.side(outerPopName, { degree: Deg.fixed(1), strategy: Strat.sequential() }), + Rel.side(innerPopName, { degree: Deg.uniform(1, 7), strategy: Strat.sequential() }), +]); +``` + +Attach to the child `Rel.table` via `relationships: [...]` and set +`iter: name` on the child so iteration drives off the joint space. + +| Build | Arms | +|---|---| +| Degree | `Deg.fixed(n)`, `Deg.uniform(min, max)` | +| Strategy | `Strat.hash()`, `Strat.sequential()`, `Strat.equitable()` | + +Row-index kinds inside a relationship child (`Attr.rowIndex(kind)`): +`ENTITY` (the outer parent index), `LINE` (the inner offset within +the parent's block), `GLOBAL` (cumulative across all parents). + +Example — TPC-H `orders ↔ lineitem` (`workloads/tpch/tx.ts`): + +```ts +const ordersSide = Rel.side("orders", { degree: Deg.fixed(1), + strategy: Strat.sequential() }); +const lineitemSide = Rel.side("lineitem", { degree: Deg.uniform(1, 7), + strategy: Strat.sequential() }); + +Rel.table("lineitem", { + ... + relationships: [Rel.relationship("orders_lineitem", + [ordersSide, lineitemSide])], + iter: "orders_lineitem", + attrs: { + l_orderkey: Attr.lookup("orders", "o_orderkey", + Attr.rowIndex(RowIndex_Kind.ENTITY)), + l_linenumber: Expr.add(Attr.rowIndex(RowIndex_Kind.LINE), Expr.lit(1)), + ... + }, +}); +``` + +Block slots on a Side (per-entity cached values) are read via +`Attr.blockRef(slot)` inside the child attrs: + +```ts +Rel.side("customer", { + degree: Deg.fixed(10), + strategy: Strat.sequential(), + blockSlots: { + c_nationkey: Draw.intUniform({ min: Expr.lit(0), max: Expr.lit(24) }), + }, +}); + +// inside child attrs: +o_custkey: Attr.blockRef("c_nationkey"), +``` + +### 6.2 `Rel.cohort` (temporal schedules) + +A Cohort is a named, bucketed schedule that picks `cohortSize` +entity ids per bucket key from `[entityMin, entityMax]`. The schedule +is stateless — repeated draws for the same `(name, bucketKey, slot)` +triple return the same entity id across runs and workers. + +```ts +Rel.cohort({ + name: "daily_users", + cohortSize: 100, + entityMin: 1, entityMax: 10_000, + bucketKey: Expr.col("ss_sold_date_sk"), // default; per-call overrides OK + activeEvery: 1, // every bucket active + persistenceMod: 30, // carry over across 30 buckets + persistenceRatio: 0.8, // 80% of slots from persistent set + seedSalt: 0xDA117, +}); + +// read inside attrs: +ss_customer_sk: Attr.cohortDraw("daily_users", Expr.lit(0)), +ss_is_active: Attr.cohortLive("daily_users"), +``` + +Use cohorts for schedules that would otherwise need a materialized +table (active-customer-on-date, seasonal-product-on-week). The +framework's bucketed LRU avoids materialization while keeping the +result deterministic across seekable workers. + +### 6.3 `Rel.lookupPop` + +A LookupPop is a **pure** sibling population: never iterated, only +read via `Attr.lookup`. Use it to bring a foreign-key column's +related data into a row without joining at DB side. + +```ts +const partLookup = Rel.lookupPop({ + name: "part", + size: N_PART, + attrs: { + p_retailprice: tpchRetailPrice(Attr.rowId()), + }, +}); + +Rel.table("lineitem", { + ... + lookupPops: [partLookup], + attrs: { + l_partkey: Draw.intUniform({ min: Expr.lit(1), max: Expr.lit(N_PART) }), + l_extendedprice: Expr.mul( + Attr.lookup("part", "p_retailprice", + Expr.sub(Expr.col("l_partkey"), Expr.lit(1))), + Expr.col("l_quantity"), + ), + }, +}); +``` + +LookupPops live behind an LRU (default 10 000 entries; override via +`STROPPY_LOOKUP_CACHE_SIZE`). Parallel workers each clone the +registry so writes never race; see `docs/parallelism.md` §4. + +**Keeping two attrs in sync across contexts.** A subtlety specific +to LookupPops: the same `Draw.*` expression evaluated at the primary +table and mirrored in a LookupPop returns different values, because +the stream seed path includes the attr's path and the two live in +different evaluation contexts. When an attr must be identical between +the iter-side population and a LookupPop that reads into it (as for +TPC-H `o_orderdate` read by lineitem), derive both from a pure +formula — row-index hash — not from a `Draw.*` call. TPC-H's +`tpchOrderdateExpr(Attr.rowIndex())` is the canonical pattern; see +`workloads/tpch/tpch_helpers.ts`. + +### 6.4 `Rel.scd2` + +SCD-2 splits the population into a historical slice and a current +slice at a compile-time boundary row. The runtime auto-injects +`startCol` and `endCol` values per row; authors list them in +`columnOrder` but not in `attrs`. + +```ts +Rel.table("customer_scd", { + size: N * 2, // historical + current + seed: SEED, + attrs: { /* ... columns ... */ }, + columnOrder: [..., "start_date", "end_date"], + scd2: Rel.scd2({ + startCol: "start_date", + endCol: "end_date", + boundary: Expr.lit(N), // compile-time constant int64 + historicalStart: Expr.lit(new Date("1900-01-01")), + historicalEnd: Expr.lit(new Date("2020-12-31")), + currentStart: Expr.lit(new Date("2021-01-01")), + currentEnd: undefined, // -> SQL NULL on current rows + }), +}); +``` + +Boundary must fold to a constant int64 at `NewRuntime` time; runtime- +varying boundaries are not supported. + +Row layout: with `size: 2*N` and `boundary: N`, rows `[0, N)` are +historical and get `historicalStart / historicalEnd`; rows `[N, 2N)` +are current and get `currentStart / currentEnd`. Each row's attrs +see the same scratch shape regardless of slice, so a single attr +schema serves both halves; the slice-specific values live only in +the auto-injected start/end columns. + +Pair SCD-2 with a Cohort (§6.2) when current rows should carry +active-over-time membership: the cohort schedules which entity ids +are live per bucket, and SCD-2 fixes the time boundaries. + +--- + +## 7. `std.*` — stdlib functions + +Every `std.*` wrapper is a thin typed shim over a Go registration in +`pkg/datagen/stdlib/`. Runtime signature checks live in Go; TS just +validates arity. + +| Function | Signature | Purpose | +|---|---|---| +| `std.format(fmt, ...args)` | string | Go-style `%d`, `%s`, `%09d`. | +| `std.hashMod(n, k)` | int64 | `splitmix64(n) mod k` — even spread over `[0, k)`. | +| `std.uuidSeeded(seed)` | string | Deterministic UUID v4 from a 64-bit seed. | +| `std.daysToDate(days)` | date | Epoch-day int64 → date scalar. | +| `std.dateToDays(t)` | int64 | Date scalar → epoch-day int64. | +| `std.lower(s)` / `std.upper(s)` | string | ASCII case. | +| `std.substr(s, i, n)` | string | UTF-8-safe substring. | +| `std.len(s)` | int64 | Rune count. | +| `std.toString(x)` | string | Format any scalar. | +| `std.parseInt(x)` | int64 | Base-10 parse. | +| `std.parseFloat(x)` | float64 | 64-bit float parse. | +| `std.permuteIndex(seed, idx, n)` | int64 | Deterministic bijection on `[0, n)`. Cycle-walking Feistel cipher over a SplitMix64 round function; parallel-safe, no state. | + +`std.call(name, ...args)` is the escape hatch when a typed wrapper +is missing; don't rely on it — add a typed wrapper instead. + +--- + +## 8. Tx-time randomness — `DrawRT.*` + +`Draw.*` evaluates inside the load-time runtime. The transaction +phase runs in k6 (not the Go evaluator), so it needs a different +path. `DrawRT.*` is the tx-time surface: each builder returns a +sobek-bound Go struct with `.sample(seed, key)`, `.next()`, +`.seek(key)`, and `.reset()` methods. + +### 8.1 Where it fits + +- **Load phase** (`Step("load_data", ...)` with `driver.insertSpec`): + use `Draw.*`. The proto arm is seeded by `(rootSeed, attrPath, + streamId, rowIdx)`. +- **Tx phase** (`export default function () { ... }` loop): use + `DrawRT.*`.

One function: + +```go +func Derive(root uint64, path ...string) uint64 { + return SplitMix64(root ^ FNV1a64(strings.Join(path, "/"))) +} +``` + +`SplitMix64` is the Steele/Lea/Flood 2014 bit-mixer (5 XORs + 2 +multiplies). `FNV1a64` is Go's `hash/fnv` 64-bit FNV-1a. The PRNG is +PCG64 seeded from `(key, key^0x9E3779B97F4A7C15)`. + +There is no alternate path. Every component that needs a per-row +key — stream draws, null decisions, cohort slotting, lookup +hashing — calls `seed.Derive` with a path composed of the attr name, +the stream id, and the row index (or equivalent sub-keys). CLAUDE.md +§6 blocks any deviation at code review. + +### 10.2 Runtime + Clone + +`runtime.Runtime` (file `runtime/flat.go`) carries: + +- **Shared (read-only after NewRuntime):** compiled DAG, column + metadata, emit slots, row count, dict map, root seed, relationship + metadata, SCD-2 state, compiled lookup and cohort metadata. +- **Per-clone (fresh each Clone):** `scratch` map, `row` counter, + per-clone `LookupRegistry`, per-clone `CohortRegistry`, fresh + block caches for relationship mode. + +`Clone()` constructs a new Runtime sharing the read-only fields and +calling `CloneRegistry()` on the cohort and lookup registries. The +CloneRegistry pattern — each registry holds an immutable compiled +spec plus a mutable per-clone LRU — is the fix for two race +conditions the pre-WI-5 codebase had when workers wrote into a shared +cache. Any new runtime-level primitive with mutable state must +implement `CloneRegistry()` and wire into `runtime/flat.go#Clone`. + +`SeekRow(i)` is O(1): every Expr is a pure function of `i`, so there +is no state to replay. This is the primitive that makes parallelism +free — see `docs/parallelism.md`. + +### 10.3 Proto wire + +TS `Rel.table(...)` produces a `PbInsertSpec` via builder helpers +that fill in the oneof boilerplate. `DriverX.insertSpec` serializes +with `DatagenInsertSpec.toBinary`, ships the bytes through the +xk6air driver binding (`Driver.insertSpecBin`), and the Go side +unmarshals and feeds into `runtime.NewRuntime`. Dicts are inlined +under `InsertSpec.dicts` keyed by FNV content hash so equal-content +dicts collapse to one entry. + +The xk6air bindings live in `cmd/xk6air/`. For tx-time randomness the +contract is different: `RegisterDict(name, bin)`, `RegisterAlphabet`, +`RegisterGrammar` return opaque int64 handles the TS DrawRT +constructors pass to `NewDrawXxx`. + +### 10.4 DrawRT internals + +File pattern: `cmd/xk6air/draw_*.go`. Each DrawRT constructor returns +a Go struct with fields cached at init time (direct arm pointer, +unboxed bounds, a pooled `*rand.Rand`). The sobek bridge exposes +`Sample`/`Next`/`Seek`/`Reset` as JS methods. The hot path bypasses +`expr.Eval` entirely — no proto decoding, no scratch map lookup, no +stream id indirection. The init-time cost buys a tight `.next()` loop +for k6's default-iteration body. + +See `cmd/xk6air/draw_ctors.go` for how `NewDrawIntUniform(seed, lo, +hi)` is wired, and `cmd/xk6air/draw_arms.go` for the per-arm +sampleable types. + +### 10.5 Seekability invariant + +Every primitive must emit `value(i) = f(rootSeed, attrPath, subKeys, +i)` where `f` is pure and its inputs don't depend on earlier rows. +That guarantees any row range can be split across any number of +workers, and each worker can start at its chunk boundary via +`SeekRow` without seeing different values than a single-worker run. + +What breaks the invariant, and is rejected at review: + +- Stateful PRNG (`math/rand` global, `rand.New` outside `seed.PRNG`). +- Cross-clone mutable state by reference (the LookupRegistry and + CohortRegistry races motivated `CloneRegistry()` in the first + place). +- Accumulating counters in the evaluator. +- Stream draws whose `(min, max)` depend on a value computed after + the draw itself. + +The regression guard is `pkg/datagen/runtime/determinism_test.go`: +every primitive ships a table-driven case that compares the row +multiset at `workers ∈ {1, 4, 16}`.

A missing/undefined branch raises a + validation error. + +### DrawRT + +- **Non-literal bounds are not supported.** DrawRT constructors are + called at module init, when the Go Runtime is not available. Pass + number, bigint, or `Expr.lit(...)` constants only. +- **Do not share a DrawRT instance across VUs.** The cursor is + non-atomic.

Use `Attr.dictAtInt` / `Attr.dictAtFloat` + to coerce on read. +- **Dicts dedupe by content.** Two `Dict.values([...])` calls with + the same entries produce the same opaque key; the InsertSpec's + `dicts` map carries one copy. You don't need to hoist a dict to a + module constant for dedup — do it only for readability. + +### Tables & relationships + +- **`columnOrder` must cover attrs + SCD-2 pair, nothing else.** + Mentioning an unknown name or duplicating a name errors at + `Rel.table` build time. +- **`iter: "relName"` is mandatory for the child of a relationship.** + Without it the runtime iterates the child's `size` directly and + ignores the relationship. +- **Block slots evaluate once per outer entity.** Use them for + per-entity random values that must be consistent across inner + rows (e.g. `c_nationkey` shared by all `o_custkey` draws within + one customer's block).

This +doc does not repeat the primitives reference — cross-linked where +relevant. + +--- + +## 1. Model + +**One dial.** Per-spec `parallelism.workers` is the single knob for +load-time parallelism. It surfaces in TS as `Rel.table({ parallelism: +N })` and on the wire as `InsertSpec.parallelism.workers`. + +There is no separate Loader. The old `pkg/datagen/loader/` package +and the `STROPPY_MAX_LOAD_WORKERS` env var were deleted in +`refactor(datagen): delete unused loader package; parallelism.workers +is the single dial`. The driver's connection pool (postgres +`maxConns`, mysql `maxOpenConns`, etc.) is the natural throttle +against over-provisioning. + +**Seekable by construction.** CLAUDE.md §5: every attribute value is +`f(rootSeed, attrPath, subKeys, rowIndex)` — a pure function. Any +worker can seek to any row without warmup. This is what makes +parallelism free; it is also the property a new primitive must +preserve. + +--- + +## 2. End-to-end trace + +How a spec with `parallelism.workers = 4` becomes four goroutines +writing concurrently. + +1. **TS.** The workload declares the table: + + ```ts + Rel.table("orders", { + size: N_ORDERS, + seed: SEED_ORDERS, + parallelism: LOAD_WORKERS || undefined, + attrs: { ... }, + }); + ``` + + The Rel.table builder packs it into a `PbInsertSpec` with + `parallelism.workers = 4`. + +2. **Wire.** `DriverX.insertSpec` serializes via + `DatagenInsertSpec.toBinary` and calls + `driver.insertSpecBin(protoBytes)` through the xk6air bridge. + +3. **Go driver.** Each driver's `InsertSpec` method unmarshals the + spec, reads `spec.GetParallelism().GetWorkers()`, and forwards to + the shared orchestrator: + + ```go + chunks := common.SplitChunks(rowCount, int(spec.GetParallelism().GetWorkers())) + err := common.RunParallel(ctx, spec, chunks, func(ctx, chunk, rt) error { + return drainChunk(ctx, chunk, rt, writer) + }) + ``` + +4. **SplitChunks.** Divides `[0, rowCount)` into `max(workers, 1)` + contiguous ranges. Every chunk holds `floor(total/workers)` rows; + the last absorbs the remainder. + +5. **RunParallel.** Builds one seed `runtime.Runtime` from the spec, + then spawns one goroutine per chunk via `errgroup`. Each goroutine + calls `seed.Clone()` → `SeekRow(chunk.Start)` on its own clone, + then invokes the per-driver drain callback. + +6. **Drain.** The callback calls `rt.Next()` `chunk.Count` times and + writes the rows through the driver-native path: `pgx.CopyFrom` + (postgres), `Table().BulkUpsert` (ydb), `sql.Exec` with + multi-row `VALUES` (mysql / picodata), `csv.Writer` per shard + (csv), or a discard (noop). + +7. **Error handling.** The first non-nil error cancels + `groupCtx`; sibling workers are expected to honor `ctx.Done` and + return promptly. `RunParallel` returns the first error. No + "continue after first failure" path. + +See `pkg/driver/common/parallel_insert.go` for the 140-line +implementation — the contract fits on one screen. + +--- + +## 3. The seekability contract + +CLAUDE.md §Parallelism discipline §1: + +> Determinism test per primitive: `workers ∈ {1, 4, 16}` → identical +> row multiset. If it fails, the primitive isn't seekable — fix it. + +Enforcement: + +- `pkg/datagen/runtime/determinism_test.go` — + `TestDeterminismAcrossWorkers` — is a table-driven sweep that + constructs a small spec per primitive, drains it via + `runtime.Clone + SeekRow` across workers ∈ `{1, 4, 16}`, sorts the + rows, and requires identical multisets. It runs under `-race` in + CI. +- New primitives land together with their determinism case. A + primitive without a case is by definition untested against the + seekability invariant and does not merge. + +Reference: `test(datagen-runtime): determinism sweep across all +primitives` in the feat/relations history. The sweep covers the 18 +Expr arms and every StreamDraw arm. + +What breaks seekability (from `docs/datagen-framework.md` §10.5): + +- Stateful PRNG (any use of Go's `math/rand` global; any + `rand.New(rand.NewSource(...))` outside `seed.PRNG`). +- Cross-clone mutable state shared by reference. +- Accumulating counters in the evaluator. +- Stream draws whose bounds depend on a value computed after the + draw. + +--- + +## 4. `Runtime.Clone` and per-worker registries + +`Runtime.Clone()` is the allocation boundary. See +`docs/datagen-framework.md` §10.2 for the field-level breakdown; this +section focuses on the parallelism-specific invariants. + +**Shared across clones (read-only after `NewRuntime`):** compiled +attr DAG, column metadata, emit slots, root seed, relationship +metadata, SCD-2 state, dict map, population sizes. + +**Per-clone (fresh allocation each `Clone()`):** `scratch` map +(the row's attr scratch), `row` counter, `inFlight` guard, cohort +`slotCache`, lookup LRU, relationship block caches. + +**The CloneRegistry pattern.** Any registry that caches compiled +data plus mutable per-worker state splits into two layers: + +```go +type LookupRegistry struct { + compiled map[string]*popPlan // immutable; shared across clones + lru *lru.Cache // per-clone; writes not raced +} + +func (r *LookupRegistry) CloneRegistry() *LookupRegistry { + return &LookupRegistry{ + compiled: r.compiled, // share + lru: lru.New(r.lru.Capacity()), // fresh + } +} +``` + +`runtime/flat.go#Clone` calls `CloneRegistry()` on the lookup and +cohort registries. The pattern is the fix for two real races: + +- **Lookup race.** Before the per-clone registry (commit + `fix(datagen-lookup): per-clone registry to stop concurrent-map + race`) the shared LRU had `fatal error: concurrent map writes` + crashes at workers ≥ 4 on real pg. The WI-3 bench report in + `docs/bench/parallelism-2026-04-24.md` documents the pre-fix + crash rate (2 of 3 reps died at w=8). +- **Cohort race.** Commit `fix(datagen-cohort): per-clone registry + to stop concurrent slotCache race` closed the same problem for the + cohort `slotCache`. No workload exercised cohorts at the time, so + the race was dormant; WI-5 closed it before TPC-DS brought + cohort-heavy specs online. + +**New runtime-level primitive with mutable state?** Implement +`CloneRegistry()` on its registry and wire it into +`runtime/flat.go#Clone`.

Setting `parallelism.workers` + +Guideline for workload authors. + +1. **Start at 1. Verify correctness first.** Row count, FK integrity, + deterministic output at `workers=1` vs `workers=4`. Only then + tune. +2. **Match the pool.** Set workers to about the number of DB + connections you expect to keep busy — typically `pool.maxConns` or + slightly less. Oversubscribing wastes goroutines blocked on + `AcquireConn`. +3. **Expect diminishing returns past ~8.** Dimension tables finish + fast regardless. Lookup-heavy specs plateau earlier because per- + clone LRUs lose the cross-worker hit-rate benefit at high fan-out + (see §7). +4. **Honor the `LOAD_WORKERS` convention.** tpcb, tpcc, tpch read + `ENV("LOAD_WORKERS", 0)` and plumb it into every `Rel.table`'s + `parallelism` field. New workloads should follow the pattern — + it makes the benching harness uniform. + +Idiomatic wiring: + +```ts +const LOAD_WORKERS = ENV("LOAD_WORKERS", 0, + "Load-time worker count per spec (0 = framework default)") as number; + +function fooSpec() { + return Rel.table("foo", { + size: N_FOO, seed: SEED_FOO, + method: DatagenInsertMethod.NATIVE, + parallelism: LOAD_WORKERS || undefined, // `undefined` falls back to 1 + attrs: { ... }, + }); +} +``` + +Setting `parallelism.workers = 0` or omitting it → the driver treats +it as 1 (`SplitChunks` clamps `workers < 1` to 1). + +--- + +## 7. Known limits + +- **Amdahl's floor.** Small populations (< ~10k rows) finish fast at + `workers=1`; parallelism cannot help. Dimension tables in every + TPC workload exhibit this. +- **Process cold-start.** ~1.5s stroppy init (k6 VM, xk6air bindings, + driver dial) is fixed per run. Bench wall-clock includes it; at + SF=1 / WAREHOUSES=1 this dominates. +- **Per-clone cache-hit regression.** Per-clone `LookupRegistry` and + `CohortRegistry` trade cross-worker cache sharing for lock-freeness. + The regression is measurable on lookup-heavy specs at workers ≥ 8: + e.g. tpch pg dropped from a "lucky" 3.73× (1/3 reps surviving pre- + fix) to an honest 2.45× post-fix. Sharded-per-pop registries (plan + §16 / stage-I Gap 2 Option 2) are the standing remediation option. +- **pg WAL serialization.** Real-DB write throughput bottlenecks on + the DB's commit path long before the generator does. tmpfs + eliminates disk seek cost but not WAL ordering. + +--- + +## 8. Future work + +Tracked in `handoff.md` and plan §13/§16; summarized here for the +parallelism-adjacent items. + +- **Sharded per-pop registry** (Gap 2 Option 2). Per-population + registry shards keyed by `entityIdx % shardCount` recover cross- + worker cache-hit rate without re-introducing the race. +- **`seed.Derive` redesign.** Drawbench shows a 67 ns/call floor + dominated by the variadic `strconv` path. Inlining FNV+SplitMix64 + for fixed path lengths is a candidate. +- **Cross-spec coordination.** Today each `InsertSpec` spawns its + own worker pool; specs run sequentially in `Step("load_data")`. + Co-scheduling (e.g. run two small-table specs concurrently while + a large-table spec warms up) would recover some wall-clock on + workloads with one dominant table. + +See `docs/datagen-framework.md` §10 for the internal shape these +changes touch.
