Dec 1, 2024December 2024 (stargate/data-api) focused on stabilizing the core data API, hardening data correctness, and upgrading tooling to support faster delivery and reliability. Key features delivered: API constants centralization and enum refactor to centralize JSON property names via a nested Names interface, reducing typos and enabling safer usage across the API. Bug fixes that improve correctness and observability: added a custom Jackson serializer for CqlVector to ensure correct formatting of vector keys for insertedIds, and enhanced error reporting for invalid document IDs by including the problematic JSON and clarifying the SHRED_BAD_DOCID_TYPE message. Maintenance and tooling improvements: updated Jackson patch versions, migrated to DSE 6.9.4, and upgraded the Maven wrapper and Maven to newer versions to improve stability and build tooling. Overall impact and accomplishments: delivered safer API constants, ensured correct primary-key behavior for vector-based keys, and improved debugging with richer error diagnostics, contributing to higher reliability and faster issue resolution. Technologies/skills demonstrated: Java, Jackson (custom serialization), DSE 6.9.4, Maven tooling, enum refactor, improved error diagnostics, and maintainability improvements.
