If not supported, those tests may need to be deferred or use a different test infrastructure. +- **PSL grammar expressibility:** Some Mongo-specific index options (e.g., `weights: { bio: 10 }`) require object-valued named arguments in PSL attributes. Verify the PSL parser can handle this; if not, consider alternative syntax. +- **Emitter integration:** The relationship between the PSL interpreter and the emitter needs clarification — does the interpreter produce the enriched contract directly, or does the emitter post-process?

The runner applies them against a live MongoDB instance. + +## What M2 adds (layer by layer) + +### 1. Index options + +M1 established the contract type `MongoStorageIndex` with `keys`, `unique`, `sparse`, `expireAfterSeconds`, and `partialFilterExpression`. The direction type `MongoIndexKeyDirection` already covers `1 | -1 | 'text' | '2dsphere' | '2d' | 'hashed'`. + +M2 adds these index options to complete the vocabulary: + +| Option | Type | Used by | Notes | +|---|---|---|---| +| `wildcardProjection` | `Record` | Wildcard indexes (`$**`) | Include/exclude fields from wildcard index | +| `collation` | `Record` | Any index | Per-index collation for case-insensitive matching | +| `weights` | `Record` | Text indexes | Field weight assignment | +| `default_language` | `string` | Text indexes | Default language for text analysis | +| `language_override` | `string` | Text indexes | Per-document language override field name | + +These options affect index behavior and must be part of the index lookup key for structural matching. + +#### Wildcard indexes + +Wildcard indexes use `$**` (or `path.$**`) as the **field name**, not as a direction value. Examples: + +```typescript +// All fields +{ field: '$**', direction: 1 } + +// Path-specific +{ field: 'attributes.$**', direction: 1 } + +// Compound wildcard (MongoDB 7.0+) +[ + { field: 'tenantId', direction: 1 }, + { field: '$**', direction: 1 }, +] +``` + +The `wildcardProjection` option only applies when the wildcard key is `$**` (not path-specific). `wildcardProjection` is part of the wildcard index's identity (it changes which fields are indexed). + +#### Index options NOT modeled + +These are excluded as legacy, debugging, or internal metadata: + +- `hidden` — debugging tool (hide index from query planner without dropping) +- `textIndexVersion`, `2dsphereIndexVersion` — internal version metadata +- `min` / `max` / `bits` — legacy 2d index coordinate bounds +- `storageEngine` — per-index storage engine config (niche) + +### 2. Validators + +MongoDB supports `$jsonSchema` validators that reject documents not matching a schema. The validator is set at collection creation or modified via `collMod`. + +#### Contract type + +```typescript +interface MongoStorageValidator { + readonly jsonSchema: Record; + readonly validationLevel: 'strict' | 'moderate'; + readonly validationAction: 'error' | 'warn'; +} +``` + +Added as an optional field on `MongoStorageCollection`: + +```typescript +interface MongoStorageCollection { + readonly indexes?: ReadonlyArray; + readonly validator?: MongoStorageValidator; + readonly options?: MongoStorageCollectionOptions; +} +``` + +#### Schema IR + +`MongoSchemaValidator` is a new concrete class extending `MongoSchemaNode`: + +```typescript +class MongoSchemaValidator extends MongoSchemaNode { + readonly kind = 'validator' as const; + readonly jsonSchema: Record; + readonly validationLevel: 'strict' | 'moderate'; + readonly validationAction: 'error' | 'warn'; +} +``` + +The existing `MongoSchemaVisitor` already has a `validator(node)` method (typed as `unknown` in M1). M2 changes this to `validator(node: MongoSchemaValidator)`. + +#### Validator diff classification + +The planner classifies validator changes: + +| Change | Classification | Rationale | +|---|---|---| +| No validator → validator added | `destructive` | New validation may reject existing documents | +| Validator removed | `widening` | Removes constraints | +| `validationAction` error → warn | `widening` | Relaxes enforcement | +| `validationAction` warn → error | `destructive` | Tightens enforcement | +| `validationLevel` strict → moderate | `widening` | Relaxes scope | +| `validationLevel` moderate → strict | `destructive` | Tightens scope | +| `$jsonSchema` body changed | `destructive` (default) | Conservative: any structural change to the schema body is treated as destructive | + +The conservative default for `$jsonSchema` body changes is intentional. Proper JSON Schema subset detection is complex and out of scope for M2. The architecture validates that the migration system can handle validator operations; comprehensive diff classification can be refined later. + +#### DDL command + +A single `CollModCommand` handles both validator and collection option changes, matching how MongoDB's `collMod` command works: + +```typescript +class CollModCommand extends MongoAstNode { + readonly kind = 'collMod' as const; + readonly collection: string; + readonly validator?: Record; + readonly validationLevel?: 'strict' | 'moderate'; + readonly validationAction?: 'error' | 'warn'; + readonly changeStreamPreAndPostImages?: { enabled: boolean }; +} +``` + +#### Operation structure + +Validator operations use `listCollections` for checks (querying `options.validator`): + +```typescript +const op: MongoMigrationPlanOperation = { + id: 'validator.users.update', + label: 'Update validator on users', + operationClass: 'destructive', + precheck: [{ + description: 'collection exists', + source: new ListCollectionsCommand(), + filter: MongoFieldFilter.eq('name', 'users'), + expect: 'exists', + }], + execute: [{ + description: 'update validator on users', + command: new CollModCommand('users', { + validator: { $jsonSchema: { ... } }, + validationLevel: 'strict', + validationAction: 'error', + }), + }], + postcheck: [{ + description: 'validator applied', + source: new ListCollectionsCommand(), + filter: MongoAndExpr.of([ + MongoFieldFilter.eq('name', 'users'), + MongoFieldFilter.eq('options.validationLevel', 'strict'), + ]), + expect: 'exists', + }], +}; +``` + +### 3. Collection options + +MongoDB collections can be created with options that affect storage and behavior. Some options are immutable after creation; others can be modified via `collMod`. + +#### Contract type + +```typescript +interface MongoStorageCollectionOptions { + readonly capped?: { size: number; max?: number }; + readonly timeseries?: { + timeField: string; + metaField?: string; + granularity?: 'seconds' | 'minutes' | 'hours'; + }; + readonly collation?: Record; + readonly changeStreamPreAndPostImages?: { enabled: boolean }; + readonly clusteredIndex?: { name?: string }; +} +``` + +`clusteredIndex` is modeled minimally — the key is always `{ _id: 1 }` and unique is always `true`, so only the optional name needs storing. + +#### Schema IR + +`MongoSchemaCollectionOptions` is a new concrete class extending `MongoSchemaNode`: + +```typescript +class MongoSchemaCollectionOptions extends MongoSchemaNode { + readonly kind = 'collectionOptions' as const; + readonly capped?: { size: number; max?: number }; + readonly timeseries?: { timeField: string; metaField?: string; granularity?: 'seconds' | 'minutes' | 'hours' }; + readonly collation?: Record; + readonly changeStreamPreAndPostImages?: { enabled: boolean }; + readonly clusteredIndex?: { name?: string }; +} +``` + +The `MongoSchemaVisitor`'s existing `collectionOptions(node)` method (typed as `unknown` in M1) is updated to `collectionOptions(node: MongoSchemaCollectionOptions)`. + +#### Mutability rules + +| Option | Set at creation | Modifiable via `collMod` | Planner behavior | +|---|---|---|---| +| `capped` | Yes | No | Conflict if changed on existing collection | +| `timeseries` | Yes | No | Conflict if changed on existing collection | +| `collation` | Yes | No | Conflict if changed on existing collection | +| `changeStreamPreAndPostImages` | Yes | Yes | `collMod` operation (widening or destructive) | +| `clusteredIndex` | Yes | No | Conflict if changed on existing collection | + +For immutable options, the planner emits a `MigrationPlannerConflict` with guidance suggesting a manual migration (drop + recreate with new options). + +#### DDL commands + +```typescript +class CreateCollectionCommand extends MongoAstNode { + readonly kind = 'createCollection' as const; + readonly collection: string; + readonly validator?: Record; + readonly validationLevel?: 'strict' | 'moderate'; + readonly validationAction?: 'error' | 'warn'; + readonly capped?: boolean; + readonly size?: number; + readonly max?: number; + readonly timeseries?: { timeField: string; metaField?: string; granularity?: 'seconds' | 'minutes' | 'hours' }; + readonly collation?: Record; + readonly changeStreamPreAndPostImages?: { enabled: boolean }; + readonly clusteredIndex?: { key: Record; unique: boolean; name?: string }; +} + +class DropCollectionCommand extends MongoAstNode { + readonly kind = 'dropCollection' as const; + readonly collection: string; +} +``` + +`CollModCommand` (defined above under Validators) also handles the mutable collection options (`changeStreamPreAndPostImages`). + +#### Operation ordering + +The planner emits operations in this deterministic order: + +1. **Collection creates** (additive) — new collections first, so indexes on them can be created +2. **Index drops** (destructive) — drop obsolete indexes before creating replacements +3. **Index creates** (additive) — new indexes +4. **Validator updates** — after structural changes +5. **Collection option updates** — after structural changes +6. **Collection drops** (destructive) — last, most destructive + +Within each category, operations are ordered lexicographically by collection name, then by index key spec. + +### 4. PSL authoring + +The Mongo PSL interpreter (`@prisma-next/mongo-contract-psl`) currently fills `storage.collections[name] = {}` — empty objects with no indexes, validators, or options. M2 adds: + +#### Index attributes + +Following the SQL PSL interpreter's pattern (`modelAttribute.name === 'index' | 'unique'`): + +- **`@@index([field1, field2], ...options)`** — compound index on named fields +- **`@@unique([field1, field2], ...options)`** — same with `unique: true` +- **`@unique`** (field-level) — single-field unique index + +Named arguments for Mongo-specific options: + +```prisma +model User { + email String @unique + bio String + lastSeen DateTime + + @@index([bio], type: "text", weights: { bio: 10 }, defaultLanguage: "english") + @@index([lastSeen], expireAfterSeconds: 2592000) + @@index([email, tenantId], sparse: true) +} +``` + +The interpreter maps these to `MongoStorageIndex` entries in `storage.collections[collectionName].indexes`. + +#### Validator derivation + +The emitter auto-derives a `$jsonSchema` validator from model field definitions. The derivation maps contract field types to BSON types: + +| Contract field type | BSON type | +|---|---| +| `String` | `"string"` | +| `Int` | `"int"` | +| `Float` | `"double"` | +| `Boolean` | `"bool"` | +| `DateTime` | `"date"` | +| `ObjectId` | `"objectId"` | +| Value object | `"object"` with nested properties | + +Non-nullable fields are added to the `required` array. Nullable fields use `bsonType: ["", "null"]`. Array fields (`many: true`) use `bsonType: "array"` with `items`. + +The depth of derivation is bounded by the contract's expressiveness — the contract carries field types, nullability, and cardinality, which maps directly to a `$jsonSchema`. Features beyond contract expressiveness (enums, pattern validation, min/max constraints) are not auto-derived. + +### 5. Canonical serialization for structural matching + +M1's `buildIndexLookupKey` uses `JSON.stringify` for `partialFilterExpression`, which is key-order dependent. M2 adds new object-valued options (`wildcardProjection`, `collation`, `weights`) that have the same issue. The lookup key computation must use a canonical serialization that produces the same string regardless of key order. + +```typescript +function canonicalize(obj: unknown): string { + if (obj === null || obj === undefined) return String(obj); + if (typeof obj !== 'object') return JSON.stringify(obj); + if (Array.isArray(obj)) return `[${obj.map(canonicalize).join(',')}]`; + const sorted = Object.keys(obj as Record).sort(); + const entries = sorted.map(k => `${JSON.stringify(k)}:${canonicalize((obj as Record)[k])}`); + return `{${entries.join(',')}}`; +} +``` + +The lookup key for M2 includes all identity-significant options: + +```typescript +function buildIndexLookupKey(index: MongoSchemaIndex): string { + const keys = index.keys.map(k => `${k.field}:${k.direction}`).join(','); + const opts = [ + index.unique ? 'unique' : '', + index.sparse ? 'sparse' : '', + index.expireAfterSeconds != null ? `ttl:${index.expireAfterSeconds}` : '', + index.partialFilterExpression ? `pfe:${canonicalize(index.partialFilterExpression)}` : '', + index.wildcardProjection ? `wp:${canonicalize(index.wildcardProjection)}` : '', + index.collation ? `col:${canonicalize(index.collation)}` : '', + index.weights ? `wt:${canonicalize(index.weights)}` : '', + index.default_language ? `lang:${index.default_language}` : '', + index.language_override ? `lo:${index.language_override}` : '', + ].filter(Boolean).join(';'); + return opts ? `${keys}|${opts}` : keys; +} +``` + +### 6. Updated DDL visitor and command executor + +The `MongoDdlCommandVisitor` interface gains methods for the new DDL commands: + +```typescript +interface MongoDdlCommandVisitor { + createIndex(command: CreateIndexCommand): R; + dropIndex(command: DropIndexCommand): R; + createCollection(command: CreateCollectionCommand): R; + dropCollection(command: DropCollectionCommand): R; + collMod(command: CollModCommand): R; +} +``` + +Adding these methods forces compile-time updates to: +- `MongoCommandExecutor` (runner — maps to MongoDB driver calls) +- `MongoDdlCommandFormatter` (CLI — produces display strings) +- `mongo-ops-serializer` (serialization/deserialization) + +#### Command executor mappings + +| Visitor method | MongoDB driver call | +|---|---| +| `createIndex` | `collection.createIndex(keySpec, options)` | +| `dropIndex` | `collection.dropIndex(name)` | +| `createCollection` | `db.createCollection(name, options)` | +| `dropCollection` | `collection.drop()` | +| `collMod` | `db.command({ collMod: name, validator: ..., ... })` | + +#### CLI formatter output + +``` +db.users.createIndex({ "bio": "text" }, { weights: { "bio": 10 }, default_language: "english" }) +db.users.createIndex({ "lastSeen": 1 }, { expireAfterSeconds: 2592000 }) +db.createCollection("events", { capped: true, size: 1048576 }) +db.runCommand({ collMod: "users", validator: { $jsonSchema: { ... } }, validationLevel: "strict" }) +db.orders.drop() +``` + +## Acceptance criteria + +### Index vocabulary +- [ ] All index key types tested through full pipeline: ascending, descending, compound, text, geospatial (2d, 2dsphere), hashed, wildcard (`$**`, `path.$**`), compound wildcard +- [ ] All index options supported and tested: `unique`, `sparse`, `expireAfterSeconds`, `partialFilterExpression`, `wildcardProjection`, `collation`, `weights`, `default_language`, `language_override` +- [ ] Index lookup key uses canonical serialization (key-order independent) for object-valued options +- [ ] DDL formatter renders all index types and options correctly + +### Validators +- [ ] `MongoStorageValidator` type in contract with `jsonSchema`, `validationLevel`, `validationAction` +- [ ] `MongoSchemaValidator` node in schema IR +- [ ] Arktype validation accepts validator definitions +- [ ] Planner generates `collMod` operations for validator changes +- [ ] Validator changes classified as widening or destructive +- [ ] Runner executes `collMod` with validator against real MongoDB +- [ ] `contractToSchema` converts validator from contract to IR + +### Collection options +- [ ] `MongoStorageCollectionOptions` type with capped, timeseries, collation, changeStreamPreAndPostImages, clusteredIndex +- [ ] `MongoSchemaCollectionOptions` node in schema IR +- [ ] Arktype validation accepts collection option definitions +- [ ] `CreateCollectionCommand` DDL class with all options +- [ ] `DropCollectionCommand` DDL class +- [ ] `CollModCommand` DDL class for mutable options and validators +- [ ] Planner generates `createCollection` with options for new collections +- [ ] Planner emits conflicts for unsupported transitions (capped changes, timeseries changes, collation changes, clustered changes) +- [ ] Runner executes collection commands against real MongoDB + +### PSL authoring +- [ ] Mongo PSL interpreter handles `@@index`, `@@unique`, `@unique` +- [ ] Mongo-specific index options parsed as named arguments (sparse, expireAfterSeconds, collation, type, weights, etc.) +- [ ] Emitter populates `storage.collections[].indexes` from PSL annotations +- [ ] Emitter auto-derives `$jsonSchema` validator from model field definitions +- [ ] Round-trip: PSL → contract → `contractToSchema` → planner produces correct operations + +### Serialization +- [ ] New DDL commands (`CreateCollectionCommand`, `DropCollectionCommand`, `CollModCommand`) serialize/deserialize correctly +- [ ] All new index options serialize/deserialize in `CreateIndexCommand` +- [ ] Arktype validation schemas for all new command kinds + +### End-to-end +- [ ] Integration test: compound indexes, TTL indexes, partial indexes, text indexes with weights, wildcard indexes → plan → apply → verify on `mongodb-memory-server` +- [ ] Integration test: validator added → `collMod` applied → verify validator on `mongodb-memory-server` +- [ ] Integration test: collection created with options (capped, collation, clusteredIndex) → verify options on `mongodb-memory-server` +- [ ] Integration test: second contract modifying validators and removing indexes → correct `collMod`/`dropIndex` operations → apply succeeds + +## Alternatives considered + +### Full JSON Schema subset detection for validator diffs + +We could implement proper JSON Schema containment checking to classify validator changes as widening vs destructive more precisely (e.g., adding an optional field is widening, adding a required field is destructive). This is algorithmically complex (JSON Schema subsumption is co-NP-hard in the general case) and not needed for the architecture validation goals of M2. The conservative approach (any body change = destructive) is safe and can be refined later. + +### Separate DDL commands per concern + +We could have `UpdateValidatorCommand`, `UpdateCollectionOptionsCommand` as separate DDL classes instead of a single `CollModCommand`. MongoDB's `collMod` is one command that handles both, and splitting it would mean the command model diverges from MongoDB's actual API. A single `CollModCommand` is simpler, matches the database, and carries optional fields for each concern. + +### Skip PSL authoring for M2 + +We could defer PSL authoring to a later milestone and continue using hand-crafted contracts. The authoring infrastructure already exists (`@prisma-next/mongo-contract-psl` with a working interpreter) and the SQL pattern for `@@index` / `@@unique` is proven. Adding Mongo index support is incremental work on existing infrastructure, and it's needed to prove the full contract-first flow (PSL → contract → migration) for MongoDB.

Downstream interpreters must parse values themselves. + +2. **No scoping.** Attribute names (`@index`, `@@map`, `@db.VarChar`) are accepted by the parser without validation. The parser does not know which attributes are valid in which context, or which arguments an attribute accepts. All validation happens in interpreters. + +3. **No function-call values in arguments.** Although `@default(now())` is recognized specially, general function calls like `wildcard()` or `raw("...")` inside attribute argument lists are not parsed as structured AST nodes — they're stored as raw strings (e.g. `"wildcard()"`, `"raw(\"...\")"`). + +4. **Single-line constructs.** Fields and attributes must fit on one line. There is no multi-line continuation syntax. + +5. **No object literal AST.** The parser tracks `{}` for delimiter balancing, so `{ status: "active" }` won't break parsing, but it's stored as a raw string with no structure.

The binding layer is also generic — it resolves names and validates structure, but doesn't know what a "model" or "index" means. Meaning is assigned by the interpreter, which receives a clean, validated AST. + +## Binding context + +The binding context is the configuration that tells the binding layer what constructs are valid. It is assembled from framework component contributions — the core framework provides base block types and common attributes, and each family/extension adds its own. + +```typescript +interface BindingContext { + readonly blockTypes: ReadonlyArray; + readonly contextDirectives: ReadonlyArray; + readonly builtinTypes: ReadonlyArray; +} +``` + +### Builtin types + +The binding context declares what scalar type names are available in the document scope: + +```typescript +interface BuiltinTypeEntry { + readonly name: string; // "String", "Int", "ObjectId", ... + readonly category: "scalar"; // all builtins are scalars +} +``` + +The core framework provides `String`, `Int`, `Boolean`, `DateTime`, `Float`, `Decimal`, `Json`, `Bytes`, `BigInt`.

The binding layer doesn't need annotations telling it "this is a field reference" — it determines that from context: this position expects an identifier, and the active scope contains field names from the enclosing entity, so the identifier resolves as a field reference. + +### Scope hierarchy + +Scopes are nested containers of named entries.

The binding layer doesn't know *why* — it just narrows the scope. + +The `referencedEntity` directive handles the cross-entity case like `@relation(references: [id])`, where `id` must resolve against the related model's fields. The `via` field indicates which piece of context determines the target entity (e.g. the field's own type expression). + +### Future: namespaced scopes + +Today, the document scope is flat — all entity names live at the top level.

This was rejected because it duplicates information that's already implicit in the scope hierarchy. The binding layer determines what an identifier refers to by combining the active scope with the expected type — no additional annotations needed. This also scales better to future namespace support, where resolution rules become more complex. + +### Why block types own their attributes + +An earlier design had attribute definitions declare their own `target: "member" | "block"`. This was inverted — block type definitions own their attribute lists. This is more natural: a block type is the authority on what's valid within it. When registering a new block type (e.g. `view`), you specify everything about it in one place. Attributes don't need to know about the blocks they appear in. + +### Why entity declarations vs context directives + +An earlier design treated all top-level blocks uniformly. We split them into entity declarations (which introduce named things with identity) and context directives (which modify the interpretation environment). The `types` block is fundamentally different from `model` — it doesn't declare a domain entity, it configures type aliases. This distinction maps to familiar concepts in other languages (declarations vs imports/macros) and will accommodate future environment-modifying constructs. + +### Why the parser doesn't special-case keywords + +The parser could have separate AST node types for models, enums, etc. (and currently does). The target design uses a single generic block AST node where the keyword is a plain string. This means adding a new block type (e.g. `view`) requires no parser changes — just a new block type definition in the binding context. The parser's job is purely syntactic. diff --git a/projects/mongo-schema-migrations/specs/psl-index-authoring-surface.md b/projects/mongo-schema-migrations/specs/psl-index-authoring-surface.md index c90fa7f3b..995d5b28a 100644 --- a/projects/mongo-schema-migrations/specs/psl-index-authoring-surface.md +++ b/projects/mongo-schema-migrations/specs/psl-index-authoring-surface.md @@ -24,15 +24,19 @@ But MongoDB supports several index features that users **cannot yet express** in These features are already supported in the contract types and migration pipeline.
