------------------------------------------
Summary: Calcite engine. Avoid redundant array allocation for
execution node hash keys
Key: IGNITE-25909
URL: https://issues.apache.org/jira/browse/IGNITE-25909
Project: Ignite
Issue Type: Improvement
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
We allocate array and copy row fields to key for hash execution nodes (hash
aggregate, hash set op, hash table spool). Instead wrapper over row can be used
to reduce object allocation.
