Apr 1, 2025For 2025-04, TencentBlueKing/blueking-dbm delivered automation and reliability improvements across cluster migrations and maintenance workflows. Key features include automated checksum ticket generation after data synchronization during master-slave rebuilds and remote migrations for MySQL and Spider clusters, with a scheduled 20-minute post-creation run to enhance data integrity.Additionally, MySQL setup/rollback now retrieves default_storage_engine and default-storage-engine to improve inheritance correctness. Bugs fixed include ensuring bk_host_ids are passed during new node installation flows for TendbCluster capacity changes; preserving original cluster data during PITR by copying data before binlog updates; and correcting checksum parameter defaults to empty lists to prevent databases/tables from being ignored across multiple flows. These changes improve data integrity, migration reliability, and operational safety, reducing manual intervention and risk in cluster reconfigurations and recoveries. Technologies/skills demonstrated include Python-based workflow enhancements, SQL query augmentation, safe deepcopy handling in PITR, and robust parameter management across migration and rebalancing flows. Business value: lowers migration and recovery risk, speeds up operational processes, and improves accuracy in setup/rollback and capacity changes.

Jan 1, 2025January 2025: Focused on strengthening data integrity during tendbHa point-in-time rollbacks in blueking-dbm. Delivered a safety feature by adding MySQLCheckSlaveDelayComponent to verify replication health and latency via SHOW SLAVE STATUS before allowing a rollback, preventing actions on unhealthy or lagging slaves. The change is implemented in TencentBlueKing/blueking-dbm and linked to commit d5f6e26f6f5d3cde452d5a45a8ba85d9d233eb7d (feat: tendbHa定点回档增加slave延迟检查 #9096). This reduces risk of data inconsistency during critical rollback operations and provides a foundation for broader replication-health checks.
