                 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
             Fix For: 1.2.0


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

“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
