I have done a decent bit of local testing but would like to perform more
testing before merging this to master. Creating pull request so that those who
may be interested can test to see how this affects performance and ensure that
all is still correct.

> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Mark Payne
> Assignee: Mark Payne
>
> While testing some corner cases, I have run into a few minor issues with some
> of the record oriented processors/libraries:
> ConvertRecord performs very poorly if the writer is the JSON RestSetWriter
> and configured to write the schema using the avro.schema attribute.
> If QueryRecord fails to parse data properly with the configured reader, it
> may roll back the session instead of routing to failure, leading the FlowFile
> being stuck on the queue. This includes an error message indicating that the
> FlowFile has an active callback or input stream that hasn't been closed.
> QueryRecord fails if referencing a field that is of UNION type.
