             Summary: Distributed sub-query support
                 Key: IGNITE-6883
                 URL: https://issues.apache.org/jira/browse/IGNITE-6883
             Project: Ignite
          Issue Type: New Feature
      Security Level: Public (Viewable by anyone)
            Reporter: Alin Andrei Corodescu
            Priority: Critical


Include behaviour similar to the distributedJoins flag for inner queries as 
well (gather data from multiple nodes). 
At the moment sub queries are run on remote nodes without being split into map 
and reduce parts and without taking into account data residing in other nodes 
(sometimes collocation is not possible).
One use case when results are affected by this behaviour is when the subquery 
contains a {code:sql}HAVING{code} clause, since the conditions can filter out 
groups for which not all the entries are on the same node.
