Oracle-Connector fails parsing a DDL statement (truncate partition)

    XMLWordPrintable

Details

    Description

      While beeing in streaming mode the Oracle-Connector fails to handle the following DDL statement. Technically this statement is fine, thus I assume the connector should be able to handle it.

      alter table tcd_abc_int truncate partition (p1);
      

      The full stacktrace looks like this and asked for creation of this ticket:

      org.apache.kafka.connect.errors.ConnectException: An exception occurred in the change event producer. This connector will be stopped.
