http://wiki.apache.org/cassandra/API#get_slice get_slice retrieves the values for either (a) a list of column names or (b) a range of columns, depending on the SlicePredicate you use. It does not allow you to filter a la SQL's WHERE. You would need to create your own index to do so, at least until secondary indices are implemented in Cassandra (not until 0.8 at least, feel free to follow https://issues.apache.org/jira/browse/CASSANDRA-749 ) On Tue, Apr 20, 2010 at 12:24 PM, Christian Torres <chtor...@gmail.com>wrote:
