-----------------------------------------

             Summary: Support server side operations on evaluating queries
                 Key: CASSANDRA-5184
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5184
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: T Jake Luciani
             Fix For: 2.0



Now that CQL3 makes it simple to create a table within a traditional cassandra row
there are many kind of simple operations we'd like to perform as a query is being evaluated.  Since the query sticks to a single node and it is effectively a sequential scan.  

If we piggy back a small function to evaluate each matching column then we could implement things like timeseries filters and efficient versions of count() min() max() and sum()

I don't have a design other than this though but I wanted to open the door to further discussion.
