-----------------------------------------

             Summary: Support objectReuse in JDBC sink
                 Key: FLINK-21367
                 URL: https://issues.apache.org/jira/browse/FLINK-21367
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / JDBC
            Reporter: Roman Khachatryan


Currently, if object reuse is enabled then JDBC sink factories will throw an exception. This prevents some use cases including recent one with Stateful Functions [1].

To overcome this, JdbcBatchingOutputFormat can implement InputTypeConfigurable and use the obtained serializer to copy the record if object reuse is enabled.
