Hi, I am new to Cassandra and trying to understand whether it's a good fit for my problems. So here is a case from my domain:
Assume that we're storing session events of users in composite columns within a column family partitioned by user id. This is from an example given about composite columns in the following page: https://github.com/Netflix/astyanax/wiki/Examples What I would like to query for is that last session events of each user. (So it's like a group-by query.) Can I get this information in a single query and would it be an efficient way to do it (regarding the schema or the query)? A CQL 3 solution would be great if possible. Any other suggestions are also welcome. Regards, -- Ersin Er
