[jira] [Created] (SPARK-31325) Control a plan explain mode in listeners via SQLConf

Takeshi Yamamuro created SPARK-31325:
----------------------------------------

             Summary: Control a plan explain mode in listeners via SQLConf
                 Key: SPARK-31325
                 URL: https://issues.apache.org/jira/browse/SPARK-31325
             Project: Spark
          Issue Type: Improvement
          Components: SQL, Web UI
    Affects Versions: 3.1.0
            Reporter: Takeshi Yamamuro


This proposes to add a new SQL config for controlling a plan explain mode in the events of (e.g., `SparkListenerSQLExecutionStart` and `SparkListenerSQLAdaptiveExecutionUpdate`) SQL listeners.

In the current master, the output of `QueryExecution.toString` (this is equivalent to the "extended" explain mode) is stored in these events. I think it is useful to control the content via SQLConf.
