One thing I dislike about spark is that EXPLAIN is in a not-so-nice format to parse programmatically. One idea is to allow explain to return the result in json. This is e.g. useful to construct a visual graph representation of the plan. One idea would be to support another string parameter, format, and make it default to string (not necessarily in this PR).
The typical thing I have used in the past to great effect is graphviz: https://graphviz.org/ and dot – so the idea is that we would get a command like:
EXPLAINFORMATGRAPHVIZSELECT * FROMFOO
which would provide the plan in graphviz format (in addition to text)
