---------------------------------------
Summary: GroupKey.Builder should not create array for every row
Key: IGNITE-24131
URL: https://issues.apache.org/jira/browse/IGNITE-24131
Project: Ignite
Issue Type: Improvement
Reporter: Maksim Timonin
Assignee: Maksim Timonin
In case SQL query with group by, by every row creates an array GroupKey just to
find whether this group already exists. In case queries operates big amounts of
rows and only few groups, this becomes non-optimal.
