January 2026 monthly wrap-up for luoyuxia/fluss: Implemented dynamic sink partitioning with distribution modes to optimize resource usage and throughput under variable partition traffic. Refactored sink logic to support dynamic partitioning, introduced new distribution modes, and added comprehensive tests to verify functionality and backward compatibility with existing configurations. Key commit: 13af6bf0afe8ebc905bafcfdc33d1a5d4a2f2473 (flink) - 'Support PARTITION_DYNAMIC sink dynamic shuffle based on partition traffics (#1784)'.

November 2025 highlights: Delivered Schema Evolution capability for Fluss, enabling ADD COLUMN support on existing tables while preserving backward compatibility. Implemented core changes to handle evolving schemas without table rewrites, and wired the changes into the Fluss server and connector stack. The feature is backed by commit ea2d61c76ca22ebb926618f7d06d4ced12c0f1d6 with reference #2010. This work reduces downtime for schema changes, accelerates iteration for data models, and improves extensibility for downstream analytics and integrations.

June 2025 monthly summary for luoyuxia/fluss focusing on the recent authentication refinement in the server pipeline. Delivered a critical bug fix by removing the keep-alive invocation in ServerAuthenticator, simplifying the authentication flow and reducing unnecessary per-RPC checks. This change, together with a streamlined AuthenticateContext interface, enhances stability, reduces latency, and improves server throughput while maintaining compatibility across RPC paths.

Month: 2025-04. Focused on stabilizing the Apache Flink CDC integration in the flink-cdc repository by delivering a critical fix for isSnapshotCompleted serialization in source splits. Implemented the fix and added tests to cover serialization/deserialization for both snapshot and streaming splits, validating correct behavior during replays and restarts. This work reduces risk of split misrehydration and data inconsistencies in CDC pipelines.

November 2024 monthly summary for luoyuxia/fluss: Focused on strengthening developer experience through comprehensive documentation enhancements across Flink reads and Fluss projects. Delivered enhancements to official docs, clarifying COUNT(*) support on log tables, partitioned-table configurations, catalog name usage, and expanding coverage of data types, log tables, logging configurations, and storage backends (Aliyun OSS and AWS S3). These efforts reduce onboarding time, improve feature discoverability, and align documentation with real-world usage of the Flink engine and Fluss project.
