Remove Depends(get_session) from POST /reset to prevent catastrophic connection pool exhaustion.
This endpoint was holding a SINGLE database connection while executing N PARALLEL embedding API calls via asyncio.gather(). For a user with 100 memories, this meant one connection blocked for potentially MINUTES (100 calls * 1-5 seconds each, even in parallel due to rate limits).
A single user triggering /reset could completely starve the connection pool, causing QueuePool timeout errors across the entire application.
The Memories.get_memories_by_user_id() function now manages its own short-lived session, releasing the connection immediately before the massive parallel embedding operation begins.
