Worked on hardening the Chroma vector database integration within the SEMOSS/Semoss repository, focusing on backend development and API integration using Java. Addressed reliability and resilience by standardizing API key handling through the X-Chroma-Token header and aligning request headers across all Chroma operations. Improved authentication error handling and ensured automatic creation of missing Chroma collections to prevent failures during data ingestion and querying. Enhanced error resilience by refining connection issue handling and refactoring query response processing. These efforts reduced failure modes, enabled faster recovery from connectivity issues, and improved maintainability and observability for ongoing database management and downstream processes.
