---------------------------------------------
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.
