This is introduced by #11476
~Maybe the root cause is https://github.com/pingcap/tidb/issues/52905~
We are improving the implementation of I_S tables, you can open a feature request to our team if there's no workaround.
What did you do?
run
create table
ddl on the upstream TiDB.What did you expect to see?
TiCDC receive and execute ddl should be very quick
What did you see instead?
The second log is printed around 23 seconds later after the first one printed.
The root cause is that following query too slow, it may takes more than 20 seconds.
Versions of the cluster
