Worked on the flyteorg/flyte repository to address a reliability issue in the in-memory auto-refresh cache’s batch processing loop. Focused on backend development using Go, the work involved correcting the loop index in the enqueueBatches function to ensure each batch item was properly marked as processing, which prevented partial processing and stale cache states during high-throughput operations. Added targeted unit tests covering both single-item and multi-item batch scenarios, enhancing test coverage and confidence in concurrent cache behavior. This contribution improved the consistency and reliability of cache operations while minimizing changes for downstream consumers and supporting robust user-facing workflows.
