This looks good, tested against a Postgres DB and works as expected, code
looks good, will merge to master.
> Add Fetch Size property to QueryDatabaseTable processor
> -------------------------------------------------------
>
> Key: NIFI-1691
> URL: https://issues.apache.org/jira/browse/NIFI-1691
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 0.6.0
> Reporter: Matt Burgess
> Assignee: Matt Burgess
>
> The QueryDatabaseTable processor does not have a way for the user to set the
> fetch size for the JDBC query. Some drivers (like Oracle) default to a fetch
> size of 1, which means result rows needs to be fetched one at a time from the
> database. This can be very slow, an improvement would be to allow the user to
> set the fetch size for the query.
> NOTE: Some drivers do not support this, either by throwing an exception or
> ignoring it (the JDBC spec marks it as a "hint to the database", the doc for
> the property should make this clear and no exception should be propagated
> through the processor if the attempt to set fetch size is unsuccessful.
