Note
- Due to limited thread resources, V4.x no longer supports configuring thread resources by task type. This parameter is removed starting with V4.0.0.
- In V4.x, you can use the
ha_mid_thread_scoreparameter to set the number of working threads for high-priority threads in migration tasks. For more information about the tenant-levelha_mid_thread_scoreparameter, see ha_mid_thread_score.
