>                 Key: SPARK-27395
>                 URL:
>             Project: Spark
>          Issue Type: Umbrella
>          Components: SQL
>    Affects Versions: 3.0.0
>            Reporter: Xiao Li
>            Priority: Major
> 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 explain how to read the plans
[e.g., the meaning of each field]. It is confusing to end users. The current format limits
us to add more more useful details to each operator, since it is already very long. We need
to reformat the query plans for better readability. 
> In this release, we need to improve the usability and documentation of EXPLAIN.
