> New format of EXPLAIN command
> -----------------------------
>
> Key: SPARK-27395
> URL: https://issues.apache.org/jira/browse/SPARK-27395
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Xiao Li
> Assignee: Dilip Biswal
> Priority: Major
> Fix For: 3.0.0
>
>
> 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.
