> Key: NIFI-3268
> URL: https://issues.apache.org/jira/browse/NIFI-3268
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.1.1
> Environment: - ubuntu 16.04
> - java version "1.8.0_111"
> - Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
> - Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
> Reporter: qfdk
> Labels: easyfix
>
> I added AUTO_INCREMENT column in GenerateTableFetch to benefit index column
> By default this processor uses OFFSET, i have problems with large data.
> somme column has index so we could use index to speed up query time.
> I posted question here :
> https://community.hortonworks.com/questions/72586/how-can-i-use-an-array-with-putelasticsearch.html
> If you indexed un column (id), you could use this sql
> ```
> select xxx
> From xxxxx
> where 200000=>id
> order by id
> limit 200000
> ```
> “OFFSET is bad for skipping previous rows.” [Online]. Available:
> http://Use-The-Index-Luke.com/sql/partial-results/fetch-next-page. [Accessed:
> 27-Dec-2016].
> Thank you in advance
