----------------------------------------------
Summary: Represent UNBOUNDED in window functions in CBO correctly
Key: HIVE-23275
URL: https://issues.apache.org/jira/browse/HIVE-23275
Project: Hive
Issue Type: Improvement
Components: CBO
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Currently we use a bounded representation with bound set to Integer.MAX_VALUE,
which works correctly since that is the Hive implementation. However, Calcite
has a specific boundary class {{RexWindowBoundUnbounded}} that we should be
using instead.
