Hi, For the moment C* does not support Group by in SelectStatement. I have started to work on CASSANDRA-10707 <https://issues.apache.org/jira/browse/CASSANDRA-10707> for adding it. Once it is implemented my plan is to add the ability to group by time.
We also plan to add support for goup by within Materialized View ( CASSANDRA-9778) <https://issues.apache.org/jira/browse/CASSANDRA-9778> [image: datastax_logo.png] <http://www.datastax.com/> Benjamin Lerer Software Engineer| +41 76 396 64 60 | benjamin.le...@datastax.com [image: linkedin.png] <http://ch.linkedin.com/pub/benjamin-lerer/2/303/784/> [image: facebook.png] <https://www.facebook.com/datastax> [image: twitter.png] <https://twitter.com/datastax> [image: g+.png] <https://plus.google.com/+Datastax/about> <http://feeds.feedburner.com/datastax> <https://github.com/datastax/> On Sat, Nov 14, 2015 at 1:52 AM, 朴元奎 <piaoyuan...@gmail.com> wrote: > I see spark can do this by UDF. > > Aggregation with Group By date in Spark SQL > < > http://stackoverflow.com/questions/30052937/aggregation-with-group-by-date-in-spark-sql > > > > http://stackoverflow.com/questions/30052937/aggregation-with-group-by-date-in-spark-sql > -- > 朴元奎 > kerwin >
