Feb 1, 2025

February 2025 performance summary focused on delivering business value through targeted feature delivery, reliability improvements, and improved documentation across two repositories (Evolveum/docs and Evolveum/midpoint). Key features delivered: - Evolveum/docs: Accurate Installation Documentation for PostgreSQL Setup. Fixed hyperlink in the installation template for versions 4.9 and later to correctly reference the relevant PostgreSQL setup page, reducing deployment errors for newer releases. - Evolveum/midpoint: MidPoint Performance Tuning: Provenance Metadata for Multivalues. Introduced a new performance tuning section and enabled provenance metadata for multivalues by default, with a configuration-based disable option and documented memory/storage/processing impact. - Evolveum/midpoint: Keycloak integration: add keycloak-client dependency and update client version. Addressed compatibility issues by updating the Keycloak client and adding the additional dependency. - Evolveum/midpoint: Maintenance and stability: dependency and version management. Upgraded Spring Boot to 3.4.3, removed hardcoded version overrides, reverted cache2k to 2.0, reverted Groovy to 4.0.24, and renamed reconciliation task to avoid conflicts. - Documentation improvements: Fixed references in native PostgreSQL docs (postgres.sql and postgres-upgrade.sql) to ensure accuracy. Major bugs fixed: - Corrected hyperlink in PostgreSQL installation documentation to point to the appropriate doc version. - Fixed file name references in native-sql design and implementation docs (postgres.sql and postgres-upgrade.sql). Overall impact and accomplishments: - Improved deployment accuracy and user experience, with clearer performance guidance and more stable build/deploy processes. Strengthened ecosystem compatibility (Keycloak), and reduced long-term maintenance by standardizing dependency versions and documenting impacts. Technologies/skills demonstrated: - Spring Boot 3.4.3, cache2k, Groovy 4.x, Keycloak integration, provenance metadata, PostgreSQL templates, and documentation templating and reference hygiene.
