Benjamin Lerer commented on CASSANDRA-10707: -------------------------------------------- I pushed a new patch that should fix the short read logic and that add support for {{PER PARTITION LIMIT}} with {{GROUP BY}}. The patch also add extra tests for range name queries. |[c* branch|https://github.com/blerer/cassandra/tree/10707-trunk]|[dtest branch|https://github.com/riptano/cassandra-dtest/compare/master...blerer:CASSANDRA-10707?expand=1]|[utests|http://cassci.datastax.com/view/Dev/view/blerer/job/blerer-10707-trunk-testall/]|[dtests|http://cassci.datastax.com/view/Dev/view/blerer/job/blerer-10707-trunk-dtest/]| > 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 > Components: CQL > 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} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
