## Proposed changes When a delete error occurs, the error message is ambiguous. ```sql mysql> DELETE FROM nebula_trade_health_trade PARTITION q3_2021 WHERE event_day = '20210706'; ERROR 1064 (HY000): errCode = 2, detailMessage = failed to execute delete. transaction id 7215554, timeout(ms) 160000, unfinished replicas: 4718319=7345841 ``` We do not know the meaning of `4718319=7345841`. Actually the former is `BackendId` and the latter is `TabletId`. I'll add an instruction here to help locate the problem quickly. The error message will be ```sql ERROR 1064 (HY000): errCode = 2, detailMessage = failed to execute delete. transaction id 7215554, timeout(ms) 160000, unfinished replicas [BackendId=TabletId]: 4718319=7345841 ```
