Please answer these questions before submitting your issue. Thanks!
What did you do? If possible, provide a recipe for reproducing the error.
execute multiple DDL consecutively in close time in pessimistic shard DDL mode.
What did you expect to see?
replicate these DDLs normally.
What did you see instead?
DDL coordination blocked.
all tables in DM-workers (returned by query-status) are synced, but some sources in DM-master (returned by show-ddl-locks) are unsynced.
this should be caused by fail to try sync shard DDL lock, sharding ddls in ddl lock *** is different with ***, then the DDL info received from DM-worker is ignored (and DM-worker will not resend again).
now, we can pause-task and resume-task to let DM-worker resend the DDL info to handle it manually.
