This topic describes the features of OceanBase Migration Service (OMS) Community Edition V4.2.11-CE.
Notice
Currently, you can upgrade OMS Community Edition V4.2.0-CE ~ V4.2.10-CE to V4.2.11-CE. You cannot upgrade OMS Community Edition V4.2.0-CE or earlier versions to V4.2.11-CE.
New features
Compatible with OceanBase Database Community Edition V4.4.1.
Supports full data migration from a StarRocks database to OceanBase Database Community Edition.
Supports migration of data from a PostgreSQL database V17.x to OceanBase Database.
Supports OMS Kubernetes cluster deployment.
Supports UOS v20.
Supports the wildcard DB feature in wildcard incremental scenarios. This feature supports the selection of a backward incremental start point during a forward switchover by adding the new wildcard DB to the allowlists of Store and incremental components.
Supports reverse incremental checkpoint selection during forward switchover. By default, the time when the reverse incremental component starts is used as the checkpoint. However, you can also choose the time when the reverse Store starts as the checkpoint for the reverse incremental component.
You can now filter records during migration of data from a TiDB database to a OceanBase Database community edition.
Supports the data retention time reminder feature for Store. If the incremental data retention period is less than the expected completion time, it displays a warning to increase the Store data retention time.
Supports x509 authentication for MongoDB data sources.
Migrate multiple vector fields from a Qdrant data source.
Usability improvements
OMS supports hot upgrade mode without interrupting the task.
The component node selection algorithm supports Random, Disk Space, Memory, and CPU.
Supports full validation of specified join fields, addressing scenarios where the primary key and unique constraints of the source table do not match those of the target table.
Optimized the display of tasks in the synchronization objects of a data synchronization task wildcard scenario.
Optimized the component blocklist and allowlist configurations.
Supports data migration of custom types in PostgreSQL.
When you migrate data between OceanBase Database Community Edition clusters, OceanBase Database automatically screens __CTAS internal tables to prevent errors.
