What did you expect to see?
The structure check for these tables to report differences.
What did you see instead?
$ ./bin/sync_diff_inspector --config ./sync-diff.conf
A total of 2 tables need to be compared
There is something error when compare structure of table, please check log info in output/sync_diff.log
