Maryann Xue updated SPARK-24802:
--------------------------------
Description:
Since Spark has provided fairly clear interfaces for adding user-defined
optimization rules, it would be nice to have an easy-to-use interface for
excluding an optimization rule from the Spark query optimizer as well.
This would make customizing Spark optimizer easier and sometimes could
debugging issues too.
# Add a new config {{spark.sql.optimizer.excludedRules}}, with the value being
a list of rule names separated by comma.
# Modify the current {{batches}} method to remove the excluded rules from the
default batches. Log the rules that have been excluded.
# Split the existing default batches into "post-analysis batches" and
"optimization batches" so that only rules in the "optimization batches" can be
excluded.
