Subject [jira] [Created] (CASSANDRA-10707) Add support for Group By to Select statement
Date Sat, 14 Nov 2015 20:37:10 GMT
Benjamin Lerer created CASSANDRA-10707:
------------------------------------------

             Summary: Add support for Group By to Select statement
                 Key: CASSANDRA-10707
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10707
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Benjamin Lerer
            Assignee: Benjamin Lerer


Now that Cassandra support aggregate functions, it makes sense to support {{GROUP BY}} on
the {{SELECT}} statements.

It should be possible to group either at the partition level or at the clustering column level.

{code}
SELECT partitionKey, max(value) FROM myTable GROUP BY partitionKey;
SELECT partitionKey, clustering0, clustering1, max(value) FROM myTable GROUP BY partitionKey,
clustering0, clustering1; 
{code}
