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.*`.

Implementation details + +One section, as requested. Everything here is background for someone +modifying the Go runtime; a workload author need not read it. + +### 10.1 Seed composition + +File: `pkg/datagen/seed/seed.go`. 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 new primitive without a +determinism case does not land. + +--- + +## 11. Gotchas & FAQ + +### Literals + +- **`Expr.lit(0.0)` emits int64.** `Number.isInteger(0.0)` is `true` + in JS, so the builder picks the int64 oneof arm. Use + `Expr.litFloat(0.0)` when the column is `Double` / `DECIMAL` and + the driver types-check ingress (YDB BulkUpsert does; pg/mysql/pico + accept either). +- **`Expr.lit(new Date(...))` emits int64 epoch-days.** Lift through + `std.daysToDate(...)` to obtain a `time.Time` value the driver + layer binds to `TIMESTAMP`/`DATETIME`. + +### Conditionals + +- **`Expr.if(cond, a, b)` requires `cond` to be a bool scalar.** + `Draw.bernoulli({p})` returns int64 `{0, 1}`; lift with + `Expr.eq(Draw.bernoulli({p: 0.5}), Expr.lit(1))` first. +- **`Expr.if` with a NULL branch.** Use `Expr.litNull()` — the + explicit NullMarker literal. 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.

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. diff --git a/docs/proto.md b/docs/proto.md index 4fbd8c3a..f51ab533 100644 --- a/docs/proto.md +++ b/docs/proto.md @@ -14,37 +14,12 @@ -

The +bench cannot measure framework-only scaling as designed until this is +fixed. + +### Proposed fix (Stage I) + +Port the `insertSpecSingle`/`insertSpecParallel` shape from +`pkg/driver/postgres/insert_spec.go` into `pkg/driver/noop/driver.go`, +branching on `workers <= 1`. 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.

Orders ↔ + lineitem is a Relationship with `Uniform(1, 7)` degree; part ↔ partsupp + is fixed fan-out of 4 via hash-derived sibling suppkeys. +4. `set_logged` — flips from UNLOGGED to LOGGED for query durability. +5. `create_indexes` — creates the ~12 secondary indexes needed for q1–q22. +6. `finalize_totals` — runs the `o_totalprice` recompute UPDATE (spec + §4.2.3 formula depends on post-load lineitems). +7. `queries` — executes q1–q22 once each, logging per-query timings. +8. `validate_answers` — diffs query results against `answers_sf1.json` + (SF=1 only; skipped otherwise). + +## Known simplifications vs spec + +- Addresses, phones, names use ASCII alphabet draws rather than dbgen's + exact character repertoire. Query match ratios shift slightly vs dbgen. +- `l_comment` / `o_comment` / `c_comment` use the spec-faithful grammar + walker (`Draw.grammar`) over the dist.dss grammar / np / vp / nouns / + verbs / adjectives / adverbs / auxiliaries / prepositions / + terminators dicts. Co-occurrence patterns track dbgen closely. +- `o_orderkey` uses the spec's sparse-key scheme (§4.2.3, per 32 keys: 8 + kept, 24 skipped); max key = 6_000_000 × SF. +- Dates and prices follow the spec formulae exactly; `p_retailprice` is + derived from partkey as spec §4.2.3 prescribes. + +## Integration test + +`test/integration/tpch_test.go` — loads SF=0.01 on tmpfs PG, runs all 22 +queries, and spot-checks selected answers. Run: + +```bash +make tmpfs-up +go test -tags=integration -run TestTpchWorkloadEndToEnd ./test/integration/... -v +``` + +## Regenerating reference JSON + +```bash +make gen-tpch-json # regenerates distributions.json and answers_sf1.json +``` + +- `distributions.json` — dists.dss parsed to JSON (nations, regions, + phone_cc, grammar, np, vp, nouns, verbs, adjectives, adverbs, + auxiliaries, prepositions, terminators). +- `answers_sf1.json` — SF=1 reference answers produced by `cmd/tpch-answers/`. diff --git a/workloads/tpch/answers_sf1.json b/workloads/tpch/answers_sf1.json new file mode
