Note
- Due to limited thread resources, V4.x no longer supports configuring thread resources by task type. This parameter is removed starting from V4.0.0.
- In V4.x, you can use the
ha_high_thread_scoreparameter to control the number of worker threads for high-priority threads such as replication, rebuild, and restore. For more information about the tenant-level parameterha_high_thread_score, see ha_high_thread_score.
