Subject [jira] [Resolved] (CASSANDRA-1592) Apply regular expression to row keys
Date Fri, 08 Apr 2011 21:44:06 GMT


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.

> 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.
