Yury Gerzhedovich updated IGNITE-21310:
---------------------------------------
Description:
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.
