Worked on enhancing multi-tenant isolation within the stargate/data-api repository by introducing a Tenant ID header for GPU plane requests. This feature ensured that tenant identifiers were consistently propagated through embedding and reranking providers’ API calls, supporting improved security and the groundwork for tenant-level accounting in GPU workflows. The implementation involved backend development and API design using Java, with a focus on robust unit testing to validate the extraction and correct usage of tenant IDs throughout the request lifecycle. No major bugs were reported during this period, reflecting a focused and well-tested approach to backend feature delivery and API reliability.
