Thank you for your wording! I really appreciate it.
I think it is a little different from GenerateTableFetch. Because
GenerateTableFetch use various kinds of DatabaseAdapter for RDB. They usually
use "ORDER BY" keyword.
But Cassandra does not have this feature. And It has specialized structure
based on Column Family, not Row
So I built this processor with range query.
