@darkz1984 I don't doubt that creating an index on the combination of `(process_instance_id, flag)` for table `t_ds_task_instance` could significantly improve the querying efficiency of the sql sentence you post in this issue, which you used to manually deleted the stuff from db. But I don't think this index could improve any of the queries in `TaskInstanceMapper.xml`. It is not meaningful for the upstream code. https://github.com/apache/dolphinscheduler/blob/dev/dolphinscheduler-dao/src/main/resources/org/apache/dolphinscheduler/dao/mapper/TaskInstanceMapper.xml -- This is an automated message from the Apache Git Service.
