Aman Mittal commented on NIFI-5307:
-----------------------------------
[~mattyb149] How to add the delimiter to each column if we are dumping the
whole result set to the output stream . To add the delimiter to we might need
to iterate over the rows along with the columns .
Also same applies for if we do need the escaping and quotes property checks !
Curious about solving this now !

> Key: NIFI-5307
> URL: https://issues.apache.org/jira/browse/NIFI-5307
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Configuration
> Affects Versions: 1.6.0
> Reporter: Tanmay Deshpande
> Priority: Major
>
> Team,
> Current Select Hive SQL processor reads each line from result set and writes
> into the file. This can be improved to directly write records in bulk to
> improve the performance. When tried with millions of rows the reading from
> Hive only takes few milliseconds but writing to file takes several minutes.

> Thanks,
