Cassandra 3.0.x introduces support for GROUP BY clauses as part of CQL statements. Add support for such queries in phantom. The details of its usage are found here.

Could you please give some guidelines how to user group by using phantom. i am waiting for this from last week.

Hi @Rajitha15 this is currently not supported in phantom and we are working to implement it as part of the next release which should happen shortly. Watch this space for updates.

[Rajitha15]

Could you please update me on this?

[alexflav23]

Hi @Rajitha15 this is being resolved as we speak, and the PR should be ready this weekend. It ended up requiring quite a lot of work and re-write to support properly, but it will be there very shortly, apologies for the delay, we will get you what you need.

I'm also interested in support for this. It doesn't appear as if anything has landed yet, though.
