Subject [jira] Commented: (CASSANDRA-980) It should be possible to delete columns by ranges
Date Wed, 14 Apr 2010 22:44:50 GMT

Tupshin Harper commented on CASSANDRA-980:
------------------------------------------

I didn't know about https://issues.apache.org/jira/browse/CASSANDRA-494 when I created this,
but given the current API, I believe remove_range_slices is more appropriate than remove_slice.

> It is not currently possible to delete a range of columns without retrieving the range
through the thrift interface and then deleting the columns by name. An efficient implementation
of this is dependent on https://issues.apache.org/jira/browse/CASSANDRA-674, but it can at
least be accomplished server-side in the current implementation so as to avoid the overhead
of the client-side communication. I'm going to attach one proposed implementation that adds
a remove_range_slices api method for parallelism with get_range_slices, but i'm not wedded
to either the implementation nor the particular api.
