James Churchman commented on CASSANDRA-571:
-------------------------------------------
defiantly, it's equivalent to doing a "select * " in sql at the moment and
thats always bad - it needs a "sub slice predicate" or similar
> API for requesting sub-slices of a range of supercolumns
> --------------------------------------------------------

> Key: CASSANDRA-571
> URL: https://issues.apache.org/jira/browse/CASSANDRA-571
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Reporter: Jonathan Ellis

> Suhail Doshi wrote in a comment to CASSANDRA-570 (a different issue):
> Ability to slice a column and specify an exact super column key, for example:
> column_1 {
> sc1: {}
> }
> column_2 {
> sc1: {}
> sc2: {}
> }
> Be able to slice by "column_1" to "column_2" but instead of grabbing every
> column, grab only super column "sc1" from each? The reasoning is that it's
> terrible to have to slice by column and get *every* super column and have it
> held in memory for the client application.
