This release introduces new data migration tasks between PostgreSQL, TiDB, and OceanBase Database, expands support for database migration to the cloud, and provides independent data validation and tag management features. It also enhances task management, improves the stability of migration validation tasks in multi-cloud environments, and boosts the flexibility and stability of data operations.
New data migration tasks
This release introduces new data migration tasks from PostgreSQL to OceanBase Database (MySQL and Oracle compatible modes) and from TiDB to OceanBase Database (MySQL compatible mode). These tasks support schema migration, full migration, and incremental synchronization, helping you quickly migrate data from PostgreSQL and TiDB to OceanBase Database. Additionally, new data migration tasks from OceanBase Database (MySQL and Oracle compatible modes) to PostgreSQL and from OceanBase Database (MySQL compatible mode) to TiDB are introduced, supporting incremental synchronization. These features allow you to synchronize data from other databases to OceanBase Database and then back to the source databases, meeting disaster recovery and business continuity requirements.
New data validation capabilities
In this release, data validation is separated from the data migration process and can be configured independently. This allows for more flexible operations without relying on the data migration workflow. In addition to full data validation, row count validation is now supported. This feature enables you to verify data by comparing the number of rows in table objects, significantly speeding up the validation process. Currently, full data validation and row count validation are supported for the following task types: MySQL -> OB_MySQL, OB_MySQL -> MySQL, OB_MySQL -> OB_MySQL, Oracle -> OB_Oracle, OB_Oracle -> Oracle, OB_Oracle -> OB_Oracle, PostgreSQL -> OB_Oracle, PostgreSQL -> OB_MySQL, and TiDB -> OB_MySQL.
Tag management capabilities
This release integrates tag management with data migration and data validation. Using the tag management feature on OBCloud, you can add tags to data migration and data validation tasks and filter tasks by tag on the task list page. This helps you better manage data migration and data validation tasks based on business attributes.
Stability enhancements
For data migration tasks with a PostgreSQL database as the source, incremental synchronization now defaults to using unique keys on the target database to determine conflict matrices. This avoids data quality issues caused by incomplete schema information in PostgreSQL database logs.
The incremental synchronization logic has been optimized to resolve the issue where original incremental DDL synchronization would block all subsequent DML executions. The serialization logic has been refined to the table level, meaning that DDL synchronization no longer blocks DML synchronization for unrelated tables.
