V4.2.1 or later

OceanBase Database

For details, see the table below. Note that the supported range includes all BP versions earlier than the latest supported version.

OceanBase Database features evolve with new versions. When a new OceanBase Database version is released, the Binlog service requires integration and adaptation. Therefore, support for OceanBase Database versions released after those listed in the table below is not guaranteed.

If your OceanBase Database version is not within the supported range, you can typically manually install the corresponding version of the obcdc dependency to adapt the Binlog service to your version. For more information, see Install obcdc.
