Sylvain Lebresne commented on CASSANDRA-4989: --------------------------------------------- If I understand what Christian is saying, he has composite columns whose first component is a timestamp and he wants the 'most recent group of columns whose first component timestamp is before time T'. > Expose new SliceQueryFilter features through Thrift interface > ------------------------------------------------------------- > > Key: CASSANDRA-4989 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4989 > Project: Cassandra > Issue Type: Improvement > Components: API > Affects Versions: 1.2.0, 1.2.1, 2.0 > Reporter: Cristian Opris > > SliceQueryFilter has some very useful new features like ability to specify a > composite column prefix to group by and specify a limit of groups to return. > This is very useful if for example I have a wide row with columns prefixed by > timestamp and I want to retrieve the latest columns, but I don't know the > column names. Say I have a row > {{row -> (t1, c1), (t1, c2)... (t1, cn) ... (t0,c1) ... etc}} > Query slice range (t1,) group by prefix (1) limit (1) > As a more general question, is the Thrift interface going to be kept > up-to-date with the feature changes or will it be left behind (a mistake IMO) > ? -- This message is automatically generated by JIRA.
