Review Comment:
I was going over to see how we can set the default to LOGICAL, which
requires some hacks. There are two options I can think of,
1. Maintaining `Parser.jj` copy in Pinot instead of extracting it from the
calcite.jar. The parser has the
[code](https://github.com/apache/calcite/blob/main/core/src/main/codegen/templates/Parser.jj#L1455)
for setting the default value as Physical. I tried to put a similar function
in our `parserImpls.ftl` to override the function, but it seems like `fmpp` has
no such overriding functionality, and copying both methods failed while
generating a parser class file.
2. Before Parsing the `Explain` SQL query, check whether the `with` option
is provided. If not, add `WITHOUT IMPLEMENTATION` in the query.
Please suggest a preferable option you have in mind or among the above two.
I will try to dig more if I can get some other trick. Thanks
