> 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.
