> Sql. Partition pruning. Introduce partition provider

> Key: IGNITE-21310
> URL: https://issues.apache.org/jira/browse/IGNITE-21310
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Konstantin Orlov
> Assignee: Evgeny Stanilovsky
> Priority: Major
> Labels: ignite-3
>
> In order to implement partition pruning, we need a component that will return
> partition id by given colocation keys' values. We already have
> HashCalculator+ColocationUtils to calculate colocation hash and
> TypesAwareHashFunction which does pretty match the same thing but for sql.
> My proposal is to introduce component that will consume values similarly to
> HashCalculator but will return particular partition id with regard to table's
> column types and number of its partitions.
> As part of this ticket, let's integrate new component into
> {{org.apache.ignite.internal.sql.engine.trait.Partitioned}} destination
> function.
