Jul 1, 2025July 2025 monthly summary for NationalSecurityAgency/datawave. Delivered a new JSON POST payload capability for the Datawave Query API, enabling clients to POST JSON payloads directly. Implemented a custom Jackson deserializer to convert flat JSON objects into the MultivaluedMap format required by the QueryExecutorBean and added a quickstart test to validate JSON POST payloads in end-to-end scenarios. This improves API usability for JSON-based clients and reduces client-side adaptation work, paving the way for broader JSON-first integrations.

Nov 1, 2024Monthly summary for 2024-11 focused on NationalSecurityAgency/datawave. This period delivered a feature enhancement to Lucene query tokenization to support multiple token variants at the same position, improving search accuracy for analyzers that yield alternate tokens at a single position. The work included introducing VariantBuilder to manage multiple token variants and refactoring tokenizeNode to handle variants while preserving the original query node and its potential variations. Unit tests were updated to cover the new variant-aware path. No explicit major bug fixes were reported this month; stability was improved through targeted refactoring and test coverage.
