December 2024 monthly summary for navikt/ung-sak focusing on feature delivery, reliability improvements, and business impact. Key features delivered: - High-rate Revurdering Batch (Høy Sats): Automated batch task to re-evaluate high-rate cases for users turning 25, with task persistence and DI adjustments to support batch processing. This enables faster, scalable re-evaluation workflows and reduces manual intervention. Notable commits include f89729aff0240b231d4a47a36a3ac139da0000a7 and 792ebfa5c4474cf749a0a389dacaa40e8abff20d; other related changes: 1c9b0f11ee14f2d4a5c4907cbd1d8340b3498b1d, 7c53a9cc7ac0f8559c649a0ed16e537de5301ddc. - Application periods data model refactor: storing start dates instead of full periods; updates to database schema and related logic; includes test fixes. Commits include a05733c4967cf29eed8d41250810642cad785a02 and 67e865b7b3799e9ce60e016627613a2894b7bf5d. - Exclude zero payout rate periods from processing: focused processing on periods with positive payout rate to enhance efficiency. Commit e48076f1b52aea13130ea1e2380083c87153a9d6. - Deployment/environment updates for SAF in Q2: pointing SAF services to Q2 environment and correcting scope for SAF. Commits 0dce31711ba97744fe2a26425ab042bcb238cf98 and 1fe1bcd3ae1da52961c11a858d71386eee808c8a. Major bugs fixed: - Withdrawal periods handling: do not store when there are no approved periods to process, saving resources. Commit 7cd5886ad7d8069755cb8dd8c19fb3014e96e943. - SatsEndringRepository data queries corrected and tests updated to improve data quality. Notable commits include 39411f8ec27b7cad580a21308dd553b4536d6c3d, 45099a19997423b2628e1164463785a2fb61b36a, c963b10518bf733fc54641925e3bd4af149efd50, c5ca5eef909bb0a304296a3b4ac195471e7b017a, d9609b8c2011fd206f46db4103033ed42b6f66e0, b389b38904e3f48b849d25d94a4cf38f2813ed34, 04ee43ba8d69282cc09278b5f211324b344b72e8. - SjekkProsessering constructor bug: fix incorrect initialization of group/saksbehandler field. Commit 070ae94a7d9ec7d8fa0e21893c505cfbad497c23. Overall impact and accomplishments: - Improved efficiency by gating processing on meaningful periods and avoiding unnecessary storage, reducing data maintenance costs and processing time. - Increased data quality and reliability through targeted query fixes and tests, enabling more accurate decisioning. - Strengthened deployment readiness with SAF Q2 environment alignment, simplifying future releases. - Demonstrated resilience and collaboration through cross-module refactors, test fixes, and constructor reliability improvements. Technologies/skills demonstrated: - Java, DI (dependency injection) adjustments, and batch processing techniques. - SQL query optimization and data quality improvements. - Database schema evolution and associated test maintenance. - Deployment automation and environment configuration (SAF, Q2). - Debugging and root cause analysis for constructor and initialization issues.
