June 2026 monthly summary focusing on key accomplishments in Flink and Spark, with emphasis on feature delivery, bug fixes, and business impact. Delivered cross-repo improvements that enhance observability, error handling, and developer productivity across Flink and Spark ecosystems.

May 2026: Implemented a conditional shared data volume mount for Flink containers when using the Paimon sink, improving data accessibility and management within the Flink–Paimon integration. Refactored deployment logic to move the cdc-data:/data mount from generic Flink services into the Paimon-specific docker-compose generator (Paimon.prepend_to_docker_compose_yaml), so the mount is applied only when Paimon is selected. This reduces configuration errors and operational toil for onboarding Flink with Paimon. No major bugs fixed this month in this repo; primary focus was feature delivery and deployment reliability.
