> Key: NIFI-2736
> URL: https://issues.apache.org/jira/browse/NIFI-2736
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Jeff Storck
> Priority: Minor
> Fix For: 1.1.0
>
>
> To build on the functionality that NIFI-2712 adds to
> QueryDatabaseTable/GenerateTableFetch, it would be beneficial to be able to
> use max value columns that are non-hierarchical.
> NIFI-2712 adds the capability to get data from tables based on a primary
> column (which uses a > to find greater values) and partition/bucket columns
> (which use >= to find equal or greater values) which are all ANDed together.
> In the case where a user would want multiple max value columns that are not
> considered hierarchical, max value columns would be ORed together with >
> (greater than), so that any max value column that increased from the last
> invocation would result in rows being returned.
