**I think we could do this, but it better do not do it again.** I check table `t_ds_task_definition_log`, it seems we have sql syntax `having count > 1` to make sure we only delete multiple records. So DML in `t_ds_task_definition_log` look good to me. But I am not sure the unique key of table `t_ds_process_task_relation_log`, although it has `having count > 1` to make sure the record is multiple. please double check table `t_ds_process_task_relation_log` unique key here @caishunfeng @JinyLeeChina @lenboo If we make sure is unique key of two tables. I think it makes sense to me. **But** as @caishunfeng said, it is a dangerous behavior due to we use `delete` syntax in DML because it will auto-run when user installs the software. Maybe we should add an optioned script about this next time. Or even use documents to alert users -- This is an automated message from the Apache Git Service.
