TemiChan commented on FLINK-38139:
----------------------------------
After merging Request #4064 into this branch, a field was added using the
pt-osc tool to address the issue of "Column size does not match the data size".
However, when the FlinkCDC task abnormally restarts (in the event of a
failover), it fails to restart successfully, reporting the same error of
"Column size does not match the data size". In contrast, when using the "ALTER
TABLE ADD COLUMN" method directly, no error is reported upon an abnormal
restart (failover).
