GenerateTableFetch Not Working with PartitionSize

[#1]

I am using GenerateTableFetch processor ( nifi 2.0) , with following configuration

Max_column is  "ID" and in some cases it is "UPDATE_DATETIME"

This configuration is working fine. 

But for  Partition size > 0 , I am getting no results.

No error message in Logs

Any Pointer ..??
