Hi!

We are trying to use the MySQL Source CDC feature to SYNC some tables using the incremental option. This feature will be needed because some tables have deletion in them and are too large to be fully synced, each time.

The problem that we are having at this moment is that, after the initial full load of the tables (Which is a success), the next sync is giving a source error:

Example:

2025-01-16 11:53:43 source ERROR blc-192.168.51.177:3306 i.d.c.b.BinlogStreamingChangeEventSource(validateChangeEventWithTable):1045 Error processing before of row in clientes because it's different column size with internal schema size 65, but before size 1, restart connector with schema recovery mode.

We encountered this issue in two separated MySQL Databases that we tried so far. The only change in the message is the table and the Schema Size.

We tried cleaning the source, creating the source from scratch, changing which table is going to be synced... And everytime the problem is the same.

I'm attaching the log of a execution with the complete messages.

From what we saw, all the specifications needed for the CDC to work were activated following the Airbyte recommendations and instructions on the following links:
https://docs.airbyte.com/understanding-airbyte/cdc
https://docs.airbyte.com/integrations/sources/mysql#quick-start
https://docs.airbyte.com/integrations/sources/mysql/mysql-troubleshooting

We thought the MySQL version could be the problem, but in the troubleshooting link, it is said that the version used (5.7) is compatible / can be used.

Any help on undestanding this and solving the issue would be appreciated!

Thanks!
