----------------------------------
Summary: BooleanSimplification rule is slow with large boolean
expressions
Key: SPARK-13658
URL: https://issues.apache.org/jira/browse/SPARK-13658
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Davies Liu
When run TPCDS Q3 [1] with lots predicates to filter out the partitions, the
optimizer rule BooleanSimplification take about 2 seconds (it use lots of
sematicsEqual, which require copy the whole tree).
It will great if we could speedup it.
