Month: 2025-12 Overview: Delivered a new entropy-based external path strategy for object storage to improve data distribution and reduce throttling, strengthening Paimon's data ingestion and access performance at scale. Key features delivered: - Entropy-Inject External Path Strategy for Object Storage: Implemented a hash-based file path selection to distribute files more evenly and avoid hotspots. Commit f15bcfe4eab858aab13c206e10d00ef84e487a80. Major bugs fixed: - None recorded this month. Overall impact and accomplishments: - Reduced throttling risk in object storage by distributing data across more paths, leading to more predictable throughput and improved end-user performance in large deployments. - Strengthened architecture for scalable data file path management with minimal code changes and reduced contention. Technologies/skills demonstrated: - Hash-based data distribution, external path strategy design, performance optimization, code instrumentation and review, and Git-based change tracking.

July 2025 monthly summary for apache/paimon focusing on DDL aggregation option validation to prevent runtime errors. Implemented validation at DDL time, introduced validateMergeFunctionFactory, integrated into AbstractFlinkTableFactory, preventing misconfigurations and significantly reducing runtime failures due to invalid aggregation configurations.
