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 > Apply regular expression to row keys > ------------------------------------ > > Key: CASSANDRA-1592 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1592 > Project: Cassandra > Issue Type: New Feature > Components: API > Affects Versions: 0.7 beta 2 > Reporter: zhu han > Priority: Minor > Attachments: cassandra-0.6.5_key_regex.patch, > cassandra-0.7.0-beta2_key_regex.patch > > > 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. -- This message is automatically generated by JIRA.
