> 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.
