Review Comment: IIUC JDBC connector isn't really a usable pipeline connector, but meant to work as a base library to support implementing sink connectors to JDBC-like databases. So why we need to require users to manage an extra `jdbc-connector.jar` since all abilities should have been packaged in `mysql-cdc-pipeline-connector`? -- This is an automated message from the Apache Git Service.
