Hi,
Two things about get_count API: 1) In the http://wiki.apache.org/cassandra/API, there is only one get_count method there: i32 get_count(string keyspace, string key, ColumnParent column_parent, ConsistencyLevel consistency_level) But as per the Thrift Client API, it looks like the valid version is: i32 get_count(string keyspace, string key, ColumnParent column_parent, SlicePredicate predicate, ConsistencyLevel consistency_level) And this is valid both 0.6.x and 0.7.beta1. Is this a documentation issue? 2) Also, looks like in Cassandra 0.7 beta 1, the SlicePredicate changed a little bit: In 0.6.x, it seems that count accepts -1 in Cassandra 0.6.x (which in practices, return all columns), but in 0.7 beta 1, negative not allowed. Is this a newly introduced changes in 0.7.x? Thanks, Regard, Dop
