------------------------------------
Summary: Runtime equality for ROW values produces incorrect results
Key: CALCITE-7678
URL: https://issues.apache.org/jira/browse/CALCITE-7678
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.42.0
Reporter: Mihai Budiu
GROUP BY, DISTINCT, JOIN, UNION, etc by ROW-typed values produces incorrect
results, because ROWs are compiled to Object[] and are compared by reference
instead of being compared by value.
