> WriteWithResult [1] in org.apache.beam.sdk.io.jdbc.JdbcIO [2] works in
> different way than expected. Difference lies in implementation of approach to
> row mappers in WriteFn and way how processRecord method works [3]. Current
> implementation left for developer responsibility for processing returned
> result set from write operation when result can be empty, one or many.
> Instead result should be iterated when next value is available, like for
> ReadFn [4]. Issue exists since improvement:
> https://issues.apache.org/jira/browse/BEAM-11873 
> In the attachment diff with possible solution.
