Cassandra is strongly recommended in the analytical process, this is why I want to test operations on aggregations of data I loaded into cassandra. But CQL does not know the sum and average function

Maybe you have to integrate with MapReduce.
I want to know a simple build-in solution from Cassandra too.

CQL does not support joins, subqueries, or aggregation; it is strictly for online or "realtime" queries. For full reportying and analytical queries, we offer DataStax Enterprise: http://www.datastax.com/products/enterprise
