Jul 1, 2025In July 2025, the datawave team delivered pivotal maintenance work that strengthens compatibility with upstream dependencies, broadens input handling, and enhances shard generation workflows. Key feature deliveries included: (1) Dependency Compatibility Maintenance with an Accumulo workaround and Hadoop 3.4.1 upgrade, accompanied by test adjustments to preserve stability; (2) Date range extension in DateNormalizer to support inputs up to year 4000, improving future-proofing and reliability; (3) GenerateShardSplits enhancements introducing new CLI controls for batching and balancer delays, a refactor to use a list, and the implementation of midpoint calculations with accompanying tests. Major bugs fixed center on stabilizing API compatibility and aligning tests with the Hadoop/Accumulo changes, reducing regression risk during environment upgrades. Overall impact: improved compatibility with external dependencies, extended data handling for future inputs, and a more robust shard generation process, enabling safer, larger-scale data queries and maintenance windows. Technologies and skills demonstrated include Java-based feature work, CLI tooling, range validation, refactoring for testability, and algorithmic enhancements for midpoint logic, all supported by targeted test coverage.
