[jira] [Updated] (SPARK-36416) Add SQL metrics to
AdaptiveSparkPlanExec for BHJs and Skew joins
[ https://issues.apache.org/jira/browse/SPARK-36416?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eugene Koifman updated SPARK-36416:
-----------------------------------
Description:
Add {{"num broadcast joins conversions"}} and {{"num skew join conversions"}}
metrics to {{AdaptiveSparkPlanExec}} so that it's easy to get a sense of how much impact AQE had on an a complex query.
It's also useful for systems that collect metrics for later analysis of AQE effectiveness in large production deployment.
