May 2026 performance summary for camunda/camunda and camunda/camunda-docs focusing on delivering foundational migrations, reliability improvements, and security-conscious enhancements that unlock the next phase of migration work and multi-tenant reliability. Key features delivered: - Migration groundwork for WriteBatchWithIndex and ZeebeTransaction refactor: removed offset overloads, simplified 7-arg/5-arg call sites to canonical forms, and updated JNI and raw access points; added test coverage (overwriteKey) to prevent duplicates and future-proof the migration path. - Testing framework modernization and transaction semantics tests: documented read-committed contract, introduced NoSnapshotIsolation testing structure, and improved lifecycle management; reorganized multi-partition tests under engine/client/multipartition; deprecated ClusteringRule in favor of ZeebeIntegration + TestCluster for cleaner lifecycles. - Environment variable resolution robustness: fixed legacy env var handling to support both camelCase and kebab-case formats, corrected a constant name typo, and added conflict warnings when both forms are set. - JDK 25 base image migration and runtime options support: updated base images across workflows, introduced optional jvm.options support in launcher scripts, and extended Docker images and dist tooling to align with JDK 25; documented ADRs and updates to release tooling. Major bugs fixed: - ExporterDescriptor identity stability: implemented equals and hashCode so exporters are consistently treated as the same logical entity when stored in maps, preventing inadvertent state loss. - Security logging improvement: avoid exposing potentially sensitive values by logging only conflicting key names in ambiguous warnings. Overall impact and business value: - Reduced risk in migration to WriteBatchWithIndex, improved test isolation and coverage for non-blocking, multi-partition scenarios, and ensured safer, more scalable runtime environments. These changes lay groundwork for faster feature delivery, more reliable deployments, and clearer operational semantics for configuration and exporter lifecycle. Technologies/skills demonstrated: - Java refactoring and JNI adjustments, WriteBatchWithIndex alignment, test architecture and lifecycle management, environment variable handling, containerization/dockerization, jvm.options, and release workflow orchestration.
