hi, i'm wondering how to do composite data storage types in CQL. I am trying to mimic the Composite Types functionality of the Pycassa client:
http://pycassa.github.com/pycassa/assorted/composite_types.html In short, in Pycassa you can do something like: --- itemTimeCompositeType = CompositeType(UTF8Type(), LongType()) pycassa.system_manager.SystemManager().create_column_family( keyspaceName, columnFamilyName, key_validation_class=itemTimeCompositeType ) ... columnFamily.insert(self._makeKey(item, time_as_integer), {field : value}) --- and then your primary key for this column family is a pair of a string and an integer. This is important because i am using ByteOrderedPartitioner and doing range scans among keys which share the same string 'item' but have different values for the integer. My motivation is that i am trying to port https://github.com/bshanks/cassandra-timeseries-py to Ruby and i thought i might try CQL. thanks, bayle
