February 2026 — Monthly summary for camunda/camunda and camunda/camunda-docs development work. Focused on delivering reliable batch processing, richer payload semantics, and simpler maintenance, while strengthening operational discipline through tests and documentation improvements. Key features delivered: non-blocking batch export with Dispatcher to avoid exporter blocking, enhanced batch dispatching with FIFO retry and improved error handling, and payload/intent enrichment to support richer data mapping. Subscription and exporter scope were simplified to improve readability and maintainability. Major bugs fixed: ensured resources unlock reliably without flush, refined Subscription shutdown, and completed proper shutdown sequencing by closing the dispatcher before transport; added missing support for custom headers to improve interoperability. Overall impact: these changes increase throughput and resilience in batch processing, reduce end-to-end latency caused by blocking exporters, and simplify maintenance and onboarding with clearer code and better docs. Improved test coverage and clearer shutdown semantics contribute to safer deployments and higher reliability. Technologies/skills demonstrated: refactoring (Dispatcher pattern, FIFO queue), non-blocking architecture, enhanced tests, documentation and config hygiene, and cross-repo collaboration across camunda/camunda and camunda/camunda-docs.
