----------------------------------------------
Summary: Missing simplification opportunity with IN and EQUALS
clauses
Key: HIVE-24154
URL: https://issues.apache.org/jira/browse/HIVE-24154
Project: Hive
Issue Type: Improvement
Components: CBO
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
For instance, in perf driver CBO query 74, there are several filters that could
be simplified further:
{code}
HiveFilter(condition=[AND(=($1, 1999), IN($1, 1998, 1999))])
{code}
This may lead to incorrect estimates and leads to unnecessary execution time.
