• Investigated Chroma client persistence issues, identifying causes of missing data and implementing code fixes to ensure data durability.
• Conducted log analysis and debugging to address Chroma DB persistence issues, formulating a recovery plan.
• Refactored the add_chunks_batch function in the Chroma client to address failure modes and standardize usage.

Achievements:

• Successfully resolved Chroma client persistence issues with detailed code changes and recovery steps.
• Improved the reliability of the Chroma database integration by refactoring the add_chunks_batch function.

Pending Tasks:

• Complete testing of the new backup script and ensure migration and persistence.
• Monitor the Chroma client for any further persistence issues and verify the effectiveness of implemented fixes.
