January 2025 performance highlights for opencga: Implemented advanced facet support and consistency improvements that directly enhance data discovery and analytics. Key developments include Job facet aggregation for JobMongoDBAdaptor with a dedicated test verifying correct counting and bucketing by tool ID, and date-based plus multi-facet support for file facets with comprehensive tests. Added CVDB client generator support across Python, R, and REST generators, and standardized the aggregation field parameter naming across libraries and endpoints. The test suite was stabilized against biodata and java-commons-lib changes, reducing regressions and speeding QA. These changes translate into more accurate counting, faster analytics, and easier cross-language client development for large-scale genomic data workloads.

In December 2024, OpenCB/OpenCGA completed a ResourceManager‑driven modernization across the platform, improving resource provisioning, reliability, and the reproducibility of analyses. We migrated to ResourceConfiguration and aligned core, catalog, and analysis components with ResourceManager changes (including master fetcher and related tooling), updating configuration files accordingly. Exomiser and Liftover workflows were updated to use ResourceManager-backed resources, with liftover resources added to configuration and associated tests updated. Server API improvements renamed the endpoint resource/downloadAll to resource/fetch with clearer parameter descriptions, and client scaffolding was generated to accelerate downstream integrations. Comprehensive test updates (JUnit) and targeted cleanups (e.g., removal of an unused import) reduced regression risk and improved build stability.
