Feb 1, 2025February 2025 monthly summary for apache/shardingsphere: A set of reliability and data integrity enhancements across replication, data migration, and job orchestration. Implemented configurable replication heartbeat for MySQL binlog to improve replication reliability, hardened the migration incremental importer for data integrity, ensured deterministic data dumps from InventoryDumper by adding ORDER BY for unique-key tables, and refined pipeline job progress persistence with clearer separation between inventory and incremental task status updates. These changes deliver stronger data consistency, operational reliability, and clearer governance for data workflows.
