-----------------------------------------
Summary: Sql. Allow hash output distribution for aggregations
Key: IGNITE-18205
URL: https://issues.apache.org/jira/browse/IGNITE-18205
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
Currently, we allow only single output distribution for aggregates, but looks
like if we have hash input distribution and all grouping set contains all of
the distribution keys we can make aggregation on remote nodes and produce hash
output distribution with the same keys. This will reduce memory consumption on
the initiator node and make some other optimizations possible.
Reference implementation can be found here: IGNITE-16396
