[GitHub] spark pull request #18169: [SPARK-20941] [SQL] Fix SubqueryExec Reuse
GitHub user gatorsmile opened a pull request:
https://github.com/apache/spark/pull/18169
[SPARK-20941] [SQL] Fix SubqueryExec Reuse
### What changes were proposed in this pull request?
Before this PR, Subquery reuse does not work. Below are three issues:
- Subquery reuse does not work.
- It is sharing the same `SQLConf` (`spark.sql.exchange.reuse`) with the one for Exchange Reuse.
- No test case covers the rule Subquery reuse.
This PR is to fix the above three issues.
- Ignored the physical operator `SubqueryExec` when comparing two plans.
- Added a dedicated conf `spark.sql.subqueries.reuse` for controling Subquery Reuse
- Added a test case for verifying the behavior
### How was this patch tested?
