[jira] [Created] (SPARK-27395) Improve EXPLAIN command

Xiao Li created SPARK-27395:
-------------------------------

             Summary: Improve EXPLAIN command
                 Key: SPARK-27395
                 URL: https://issues.apache.org/jira/browse/SPARK-27395
             Project: Spark
          Issue Type: Umbrella
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Xiao Li


Currently, when the query is complex or the output schema is long, the outputs of our EXPAIN command are not readable. Our documentation does not document how to read the plans. It is confusing to end users. In this release, we need to improve the usability and documentation of EXPLAIN. For example, reformatting the outputs of EXPLAIN and we can add more useful details of each operator.
