# What does this PR do? This PR updates the sqlite-vec database calls to be non-blocking. Note that each operation creates a new connection, which incurs some performance overhead but is reasonable given [SQLite's threading and connections constraints](https://www.sqlite.org/threadsafe.html). Summary of changes: - Refactored `SQLiteVecIndex` class to store database path instead of connection object - Added `_create_sqlite_connection()` helper function to create connections on demand - Ensured proper connection closure in all database operations - Fixed test fixtures to use a file-based SQLite database for thread-safety - Updated the `SQLiteVecVectorIOAdapter` class to handle per-operation connections This PR helps chip away at https://github.com/meta-llama/llama-stack/issues/1489 ## Test Plan sqlite-vec unit tests passed locally as well as a test script using the client as a library. ## Misc FYI @varshaprasad96 @kevincogan Signed-off-by: Francisco Javier Arceo <farceo@redhat.com> |
