obbinlog V4.3.6

V4.3.6.8

Version information

• Release date: September 20, 2026
• Version: V4.3.6.8

Major changes

• Added support for OceanBase Database V4.2.5.8, V4.4.2.3, and V4.6.0.1.

• Optimized the performance of Binlog log conversion and subscription delivery to reduce CPU, I/O, and memory overhead.

• Added idempotency support for STOP BINLOG INSTANCE. If an instance is already stopped and has no conflicting lifecycle task, repeated requests return success immediately.

Bug fixes

• Fixed an issue where the status check incorrectly reported that LogProxy was not running when it was deployed in a symbolic-link directory.

• Fixed an issue where special characters in the MetaDB password produced an invalid Binlog configuration file and caused deployment to fail.

• Fixed an issue where frequent writes to and cleanup of the instances_gtid_seq table could cause MetaDB queries to time out.

• Fixed an issue where creating a Binlog instance could incorrectly report insufficient node memory when the host had high memory cache usage.

• Fixed an issue where SET and ENUM data could become inconsistent after incremental Binlog synchronization when the GBK character set was used.

• Fixed an issue where eTransfer converted each incremental DDL statement twice when binlog_ddl_convert was enabled, increasing parsing latency.

Version usage restrictions

ODP

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.
