Hi Leonard, Sorry I missed this. I have suggested that these database specific maven artefacts be shaded in line with the SQL style connectors. Also each brings in a copy of core [1]. So we will have duplicate version of core brought in. I suggest:
* We shade these database specific Maven artifacts * We change the dependancy score on core to provided. So we do not bring in multiple versions of core. If there is no appetite for this as the shaded version of a connector normally brings in everything, maybe we change core to include the database name in the shading. * I notice that the parent [2] brings in all the databases. This seems inconsistent with the splitting approach. What was the thinking here? * Document this in more detail so it is obvious what artefacts should be used for SQL table data stream APIs. I am happy to be involved in improving this, but want to get consensus first. WDYT? Kind regards, David. [1]https://mvnrepository.com/artifact/org.apache.flink/flink-connector-jdbc-core.

For example you can find JDBC MySQL connector via the URL [3]. Of course that a more clear documentation in release announcement is welcome.
