Jonathan Ellis resolved CASSANDRA-1592.
---------------------------------------
Resolution: Won't Fix
it would be nice to allow generic stored functions/procedures to filter result
sets server-side, but limiting to regexp is not sufficiently general-interest.
> Apply regular expression to row keys

> Project: Cassandra
> Issue Type: New Feature
> Components: API
> Affects Versions: 0.7 beta 2

> Sometimes, the client needs to apply advanced filtering to row keys to carry
> out ad-hoc queries. Current implementation only supports prefix-match row
> filtering. This ticket is to extend the get_range_slices() API to filter the
> row keys by regular expression.
> It can also be extended to filter the column names by regex.
