Jul 1, 2025July 2025 performance highlights for GSA/datagov-harvester. Delivered key features that improve export performance, user visibility, and security, while elevating QA practices and maintainability. Implemented a streaming CSV export generator for harvest errors and large downloads to enable memory-efficient processing and faster end-user exports, with integration tests. Enhanced Harvest Jobs/Errors UI with multi-pagination, improved job table presentation, and dynamic source name display; included code refactors to support view data and updated templates. Strengthened security posture by adding integrity checks for external JavaScript libraries and adjusting script loading. Advanced QA and code quality through linting, test organization, assertion updates, and UI test reliability improvements. These results collectively boost data throughput, operator visibility, and security while reducing maintenance overhead and accelerating time-to-value for users.

May 1, 2025May 2025 monthly performance for GSA/datagov-harvester: Delivered targeted resource management and reliability improvements to the harvesting workflow, with a focus on 5G testing readiness, job lifecycle robustness, and code quality. The effort included temporary resource tuning for HARVEST_RUNNER_TASK_MEM during 5G IOOS testing (added env var, increased memory, and subsequent deprecation/removal), architectural work to enable cleanup and retry pathways for fault tolerance, and essential code cleanup that removed a redundant import in tests. Collectively, these changes enhance operational reliability, observability of the harvesting pipeline, and maintainability with minimal risk to production behavior.
