Lars Francke commented on HIVE-18513:
-------------------------------------

Thanks Jason. If that's all that needs changing I can try to provide a patch as 
well.

 

Can we also get some documentation around this feature? I cannot find any words 
on memory management for example. Where are results stored/kept?

> Add a query results cache that can save the results of an executed Hive query 
> for reuse on subsequent queries. This may be useful in cases where the same 
> query is issued many times, since Hive can return back the results of a 
> cached query rather than having to execute the full query on the cluster.
