[jira] [Updated] (CASSANDRA-5184) Support server side operations on evaluating queries

["T Jake Luciani (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-5184?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

T Jake Luciani updated CASSANDRA-5184:
--------------------------------------

    Description: 
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 wanted to open the door to further discussion.

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