FYI, it is not possible to skip validation because validated SqlNode can
only be converted to a RelNode. The engine will check and halt if you are
trying to convert Sql to Rel directly without passing validation.

This is in Scala.

I am curious about your use case. Are you not losing out on the
optimisations of Calcite when you are using Spark? Is it possible for you
to share a general approach where we will be able to keep the optimisations
done by Calcite and use Spark on top of it?

Hello all,
I was wondering if there's any virtue in creating an operator like UNNEST
by having a similar implementation like that of SqlUnnestOperator.
(SqlExplodeOperator maybe)
The functionalities are close but there are nuances that I have not
discovered yet.
My approach was kind of a hack :

with you if we are on the same page. Thanks!

*I was wondering if* the same could be achieved in a planner rule. It may
not be a good idea but, for the sake of trying it out, do you think it is
possible? If yes, could you please give me a rough road map.
Thank you for your time and patience!

Hello Everyone,
I wanted to know how one can leverage existing dialects to add new
functions or rename the occurrence of a specific function (or an operator).
For example, a query in Spark SQL - "SELECT EXPLODE(ARRAY['1', '2'])" will
only work in Postgres if it is rewritten as "SELECT

Maybe I am missing something. Please feel free to share your comments. :)

Hello Askar,
Thank you so much for taking the time to compile the list I shall try them.

Is this possible? Any recommendations or suggestions are welcome. Even if
the approach feels wrong please let me know. :)
