Does Cassandra support parallel query processing?

hi guys,

I'm going to build a warehouse with Cassandra. There are a lot of range and aggregate queries. 

Does Cassandra support parallel query processing?(both on single box and cluster)

In general read queries run on multiple nodes. But each node computes the complete result to the query. 

There is no support for aggregate queries.
