Thanks, let me modify this. I'm not using fake-to-starrocks.conf because I want to test incremental data. I'm not using mysqlcdc_to_starrocks_with_schema_change.conf because it uses shop.sql from mysql-cdc, which doesn't contain multiple tables. I'm going to modify this now.

Sorry, there was a problem with my local code. I have fixed it now. Please help me take a look again. Thank you！
