Christian Spriegel commented on CASSANDRA-1592:
-----------------------------------------------
Any chance that anybody came up with a solution for this in the meantime?
We are facing the same problem here. So far our solution is to load lots of
columns and then do a regex on the column key in our application (Not on the
row key!).
May I ask what the problem is with regex? Is it because of binary keys? Beside
from that I would say that regex is as universal as it can be.
Thanks in advance for any feedback, Ch

> 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.
