Denis Magda updated IGNITE-6883:
--------------------------------
Component/s: sql
> 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)
> Components: sql
> Reporter: Alin Andrei Corodescu
> Priority: Minor
>
> 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.
