During 2025-10, the team delivered critical features and stability fixes across RS-PYTHON rs-server and rs-client-libraries, driving reliability of user-owned resources, enhanced data discovery, and a more maintainable release pipeline. Key outcomes include: - Robust user ownership and removal workflows with consolidated owner extraction, explicit user parameter passing for removals, and unified link adaptation in the User Catalog. This reduces ownership-related errors and stabilizes publishing of user-owned resources, supported by updated tests and documentation. - Advanced CQL2 filter extensions with interval operations and pre-processing, integrated into the catalog and ADGS server, enabling more expressive, performant filtering and broader test coverage. - Correct handling of date arithmetic in CQL2 filters, fixing date calculation formatting to ensure precise datetime results after operations. - Generic Auxip staging flow improvements (v1–v4) with artifact creation, refactoring for clarity and maintainability, and smoother multi-version deployment workflows. - Comprehensive quality and tooling improvements across rs-server and rs-client-libraries, including lint fixes, regression reverts, tests stabilization, and SonarQube alignment, plus reliable artifact builds. Impact: - Improved reliability and correctness for user-owned resources and resource removal, reducing operational risk. - More powerful and trustworthy search capabilities with CQL2 extensions, accelerating data discovery. - Faster, more predictable release cycles with stable artifact generation and cleaner project structure. - Higher code quality and maintainability, lowering long-term maintenance costs and enabling safer refactors. Technologies/skills demonstrated: - API design and ownership semantics, REST/URL handling, and test-driven improvements - CQL2 filtering, interval operations, and test coverage expansion - Staging workflows, artifact pipelines, and multi-version orchestration - Linting, code quality tooling, and SonarQube compliance
