Denis Magda commented on IGNITE-4523:
-------------------------------------
[~ascherbakov], the feature is planned for 2.0 release. What are the chances
you complete it in time?
> Allow distributed SQL query execution over explicit set of partitions

> Key: IGNITE-4523
> URL: https://issues.apache.org/jira/browse/IGNITE-4523
> Project: Ignite
> Issue Type: Improvement
> Components: cache, SQL
> Affects Versions: 1.8
> Reporter: Alexei Scherbakov
> Assignee: Alexei Scherbakov
> Labels: important
> Fix For: 2.0
>
>
> 3Currently distributed SQL query is executed on all nodes containing primary
> partitions for a cache, sending map query requests on all nodes in grid.
> Sometimes we know in advance which partitions hold a data for query, on
> example, in case of custom affinity function.
> Therefore it's possible to reduce number of nodes receiving map query request
> by providing explicit set of partitions, which will give significant
> performance advantage and traffic reduction in case of very large clusters.
> Internally we already have such functionality, so the only necessary thing is
> to provide public API for what.
