Jan 1, 2026Month: 2026-01 | DataHub (datahub-project/datahub) Concise monthly summary focusing on business value and technical achievements: Key features delivered: - Kafka Topic Partition Resize and Safety Enhancements: Enables automatic resizing of Kafka topic partitions based on configuration, with safety improvements during upgrades by making automatic partition increases opt-in by default. Included refactoring of Kafka-related classes for improved readability. Notable commits: f395a1a0e7bfba115f401f8d33681d9401ec3793; 765ed54a1f475245d33c5ab78d16a31e37a107bd; 27ebfa55f08d285789d8f325f3f8afcdb88f483f. Major bugs fixed: - Safety default for partition increases corrected to opt-in behavior to prevent unexpected changes during upgrades; DATAHUB_AUTO_INCREASE_PARTITIONS now false by default, with explicit opt-in required. Notable commit: 765ed54a1f475245d33c5ab78d16a31e37a107bd. Overall impact and accomplishments: - Substantial improvement in upgrade safety and data governance through configurable, opt-in partition resizing and enhanced data integrity validation. The work reduces upgrade risk and operational surprises while maintaining system scalability. Technologies/skills demonstrated: - Kafka integration and configuration-driven behavior, Java naming and code readability improvements, pre/post-patch validation patterns, and data integrity enforcement.
