Critical: Database session token validation failed due to concurrency issue in tRPC auth context

[cbrain-dev-new]

Description

A critical error has occurred, reported by Sentry, involving a cosine distance query timeout in the vector database during concurrent insertion under pgvector. This is causing a failure in the database session token validation within the tRPC authentication context.

Impact

• Affects all database operations relying on cosine distance queries under concurrent conditions.
• Potentially blocks user authentication sessions.

Steps to Reproduce

1. Perform concurrent insertions into the vector database while executing cosine distance queries.
2. Observe the timeout error resulting in session token validation failure.

Required Actions

• Analyze and optimize the query handling in the pgvector setting.
• Investigate concurrency control measures and session management.
• Implement a fix to prevent timeout and ensure robust authentication.
