Pavel Pereslegin reassigned IGNITE-18224: ----------------------------------------- Assignee: Pavel Pereslegin > Sql. Allow hash output distribution for SET relations > ----------------------------------------------------- > > Key: IGNITE-18224 > URL: https://issues.apache.org/jira/browse/IGNITE-18224 > Project: Ignite > Issue Type: Improvement > Components: sql > Reporter: Konstantin Orlov > Assignee: Pavel Pereslegin > Priority: Major > Labels: ignite-3 > > Currently, we allow only single output distribution for SET operations, but > looks like if we have hash input distribution and projected columns contains > all of the distribution keys we can execute SET operator 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 -- This message was sent by Atlassian Jira (v8.20.10#820010)
