Vladimir Ozerov updated IGNITE-10566:
-------------------------------------
Labels: (was: iep-24)
> SQL: Map query should operate on it's own list of partitions
> ------------------------------------------------------------
>
> Key: IGNITE-10566
> URL: https://issues.apache.org/jira/browse/IGNITE-10566
> Project: Ignite
> Issue Type: Task
> Components: sql
> Reporter: Vladimir Ozerov
> Priority: Major
>
> Currently we merge extracted partitions from multiple map queries using
> {{OR}} semantics. The this list is used for execution of all queries. That
> is, consider that user's query was split into two map queries {{A}} and {{B}}
> with target partitions {{1}} and {{2}} respectively. Instead of executing {{A
> -> 1}} and {{B- > 2}} we will execute {{A -> 1, 2}} and {{B -> 1, 2}}, what
> leads to waste of resources.
> See {{GridH2QueryRequest#qryParts}} as a starting point.
