      When running Debezium MySql connector, the connector cannot parse DDL changes if the change has RESTRICT constraint in it.

      The exception I get comes from the BinLogReader and it's a parsing exception.

      I even tried running the Engine with the following configuration:

      .with("event.deserialization.failure.handling.mode", "warn")
      .with("include.schema.changes", "false")
      

      but it didn't help. This is critical since We can't work with debezium after this error occurs, since it's stuck on the binlog's position.

      This is the exception:
