- OceanBase Database V4.x does not support configuration of thread resources by task type due to limited thread resources. This parameter has been deprecated since OceanBase Database V4.0.0.
- In OceanBase Database V4.x, you can use the
ha_mid_thread_scoreparameter to specify the number of worker threads for high-availability medium-priority tasks such as migration tasks. For more information about the tenant-level parameterha_mid_thread_score, see ha_mid_thread_score.
server_data_copy_out_concurrency specifies the maximum concurrency for data migration from a single node.
