-------------------------------------

[~heigebupahei] The current `explain` syntax is just for showing the planinfo, 
if we want to override something to the real plan which is for execution, I 
suggest to extend current compiled plan, as we have such ways to compile a 
query and execute the compiled plan:
{{{}{}}}{{{}{}}}
{code:java}
COMPILE PLAN FOR '<your_path.json>' <insert_query>
EXECUTE PLAN FOR '<your_path.json>'{code}
(Also adding new mode to current `ExplainDetail` is a public api change, there 
should be a

 discussion)

Regarding to the motivation 'combine it with the parameter 
`pipeline.jobvertex-parallelism-overrides` to set up my task parallelism', 
could you explain more about it?
