Aug 1, 2025Concise monthly summary for 2025-08: Implemented standardization of query planning in the Query Metric Service by migrating from DatePartitionedQueryPlanner to DefaultQueryPlanner within NationalSecurityAgency/datawave. This change ensures consistent query planning behavior across metrics, reduces potential inconsistencies in query metrics, and lays groundwork for future optimization and easier maintenance.

Jun 1, 2025June 2025 monthly summary for NationalSecurityAgency/datawave: Delivered two key features centered on data exploration capabilities and observability. Implemented explicit ResultSet.TYPE_SCROLL_INSENSITIVE in the CachedRunningQuery service to enable scrollable cursors and advanced ResultSet methods, facilitating efficient navigation of large result sets. Upgraded the Datawave metric API to version 7.24.0 with no code changes, ensuring compatibility with newer metrics features and improved observability. No user-facing bug fixes were completed this month; focus was on foundational capability enhancements and maintainability.

May 1, 2025May 2025: Datawave (NationalSecurityAgency/datawave) — Focused on stabilizing core metadata handling, improving diagnosability, and aligning release discipline across the stack. Key outcomes include a fixed TypeMetadata caching bug, yield support with pre-yield metrics in Ivators/Iterators, broad metadata-utils upgrades across modules, coordinated versioning/tags for microservice parents, and a structural refactor to a shared datawave-microservice-parent with Spring Boot upgrades. Observability improvements include enhanced logging for ModelBean exceptions and ivarator cache activity. Business value: faster, more reliable metadata processing; clearer diagnosability; reduced configuration drift; streamlined maintenance and releases.
