Sounds great. currently DM will stop at that error so user can use [`handle-error`](https://docs.pingcap.com/tidb-data-migration/stable/handle-failed-sql-statements#handle-error) to replace that SQL, but an auto-conversion feature is definitely better. Could you give an exmaple...

@namco1992 LGTM, and for incremental phase, function `handleSpecialDDLError` could be used to detect unsupported collation error and rewrite SQL

Hi, do you need some help to implement this @namco1992

Take your time, and if you need some help you could comment here or join [sig-migrate in slack](https://slack.tidb.io/invite?team=tidb-community&channel=sig-migrate&ref=github_sig)

lgtm, and I think `dumplings` could be an alias for `mydumpers`, no need to give a warning

for 1.1, seems the failure is caused by multiple mysql instance hiding from a same IP/source-id, so there maybe mixed server_uuid/`ServerID` for a relay unit. ``` [2021/03/22 12:29:06.581 +00:00] [DEBUG]...
