The "API" page has been changed by TylerHobbs. The comment on this change is: get_count takes a predicate. http://wiki.apache.org/cassandra/API?action=diff&rev1=23&rev2=24 -------------------------------------------------- Retrieves slices for `column_parent` and `predicate` on each of the given keys in parallel. Keys are a `list<string> of the keys to get slices for. - This is similar to `get_range_slice` (Cassandra 0.5) except operating on a set of non-contiguous keys instead of a range of keys. + This is similar to `get_range_slices`, except it operates on a set of non-contiguous keys instead of a range of keys. === get_count === - . `i32 get_count(key, column_parent, consistency_level)` + . `i32 get_count(key, column_parent, predicate, consistency_level)` - Counts the columns present in `column_parent`. + Counts the columns present in `column_parent` within the `predicate.` The method is not O(1). It takes all the columns from disk to calculate the answer. The only benefit of the method is that you do not need to pull all the columns over Thrift interface to count them.
