Ashwin Bharambe	bd5ad2963e	refactor(storage): make { kvstore, sqlstore } as llama stack "internal" APIs (#4181) ... These primitives (used both by the Stack as well as provider implementations) can be thought of fruitfully as internal-only APIs which can themselves have multiple implementations. We use the new `llama_stack_api.internal` namespace for this. In addition: the change moves kv/sql store impls, configs, and dependency helpers under `core/storage` ## Testing `pytest tests/unit/utils/test_authorized_sqlstore.py`, other existing CI	2025-11-18 13:15:16 -08:00
Ashwin Bharambe	2c43285e22	feat(stores)!: use backend storage references instead of configs (#3697) ... **This PR changes configurations in a backward incompatible way.** Run configs today repeat full SQLite/Postgres snippets everywhere a store is needed, which means duplicated credentials, extra connection pools, and lots of drift between files. This PR introduces named storage backends so the stack and providers can share a single catalog and reference those backends by name. ## Key Changes - Add `storage.backends` to `StackRunConfig`, register each KV/SQL backend once at startup, and validate that references point to the right family. - Move server stores under `storage.stores` with lightweight references (backend + namespace/table) instead of full configs. - Update every provider/config/doc to use the new reference style; docs/codegen now surface the simplified YAML. ## Migration Before: ```yaml metadata_store: type: sqlite db_path: ~/.llama/distributions/foo/registry.db inference_store: type: postgres host: ${env.POSTGRES_HOST} port: ${env.POSTGRES_PORT} db: ${env.POSTGRES_DB} user: ${env.POSTGRES_USER} password: ${env.POSTGRES_PASSWORD} conversations_store: type: postgres host: ${env.POSTGRES_HOST} port: ${env.POSTGRES_PORT} db: ${env.POSTGRES_DB} user: ${env.POSTGRES_USER} password: ${env.POSTGRES_PASSWORD} ``` After: ```yaml storage: backends: kv_default: type: kv_sqlite db_path: ~/.llama/distributions/foo/kvstore.db sql_default: type: sql_postgres host: ${env.POSTGRES_HOST} port: ${env.POSTGRES_PORT} db: ${env.POSTGRES_DB} user: ${env.POSTGRES_USER} password: ${env.POSTGRES_PASSWORD} stores: metadata: backend: kv_default namespace: registry inference: backend: sql_default table_name: inference_store max_write_queue_size: 10000 num_writers: 4 conversations: backend: sql_default table_name: openai_conversations ``` Provider configs follow the same pattern—for example, a Chroma vector adapter switches from: ```yaml providers: vector_io: - provider_id: chromadb provider_type: remote::chromadb config: url: ${env.CHROMADB_URL} kvstore: type: sqlite db_path: ~/.llama/distributions/foo/chroma.db ``` to: ```yaml providers: vector_io: - provider_id: chromadb provider_type: remote::chromadb config: url: ${env.CHROMADB_URL} persistence: backend: kv_default namespace: vector_io::chroma_remote ``` Once the backends are declared, everything else just points at them, so rotating credentials or swapping to Postgres happens in one place and the stack reuses a single connection pool.	2025-10-20 13:20:09 -07:00
Matthew Farrellee	cffc4edf47	feat: Add optional idempotency support to batches API (#3171) ... Implements optional idempotency for batch creation using `idem_tok` parameter: * **Core idempotency**: Same token + parameters returns existing batch * **Conflict detection**: Same token + different parameters raises HTTP 409 ConflictError * **Metadata order independence**: Different key ordering doesn't affect idempotency **API changes:** - Add optional `idem_tok` parameter to `create_batch()` method - Enhanced API documentation with idempotency extensions **Implementation:** - Reference provider supports idempotent batch creation - ConflictError for proper HTTP 409 status code mapping - Comprehensive parameter validation **Testing:** - Unit tests: focused tests covering core scenarios with parametrized conflict detection - Integration tests: tests validating real OpenAI client behavior This enables client-side retry safety and prevents duplicate batch creation when using the same idempotency token, following REST API closes #3144	2025-08-22 15:50:40 -07:00
