We can add a config for a certain behavior if it makes sense, but the most
important thing we want to reach an agreement here is: what should be the
default behavior?
Let's explore the solution space of table insertion behavior first:
At compile time,
1. always add cast
2. add cast following the A
That is really interesting re: the recent threads about the value of
log() and pow() in the JVM. I think it's worth copying to dev@ here.

TL;DR is: take the below as feedback to consider, and proceed as you
see fit. Nobody's suggesting you can't do this.

I understand spark is making the decisions, i'm say the actual final effect
of the null decision would be different depending on the insertion target
if the target has different behaviors for null.

This is why we want to introduce the ANSI mode, so that invalid cast fails
at runtime. But we have to keep the null behavior for a while, to keep
backward compatibility. Spark returns null for invalid cast since the first
day of Spark SQL, we can't
You can try EXPLAIN COST query and see if it works for you.

I think there is no way of doing that (at least don't remember one right
now). The closer I remember now, is you can run the SQL "ANALYZE TABLE

Actually I didn't have any of the GC tuning in the beginning and then

Happy to discuss this here but you're also invited to bring those points up
at dev@training as other projects might have similar concerns.
The request for assistance still stands. If anyone here is interested in
helping out reviewing and improving the material please reach out.

Thanks, guys. Let me probably mimic the template and open a PR soon -
currently I am stuck in some works. I will take a look in few days later.

I would remove the all GC tuning and add it later once you found the underlying
root cause. Usually more GC means you need to provide more memory, because
something has changed (your application, spark Version etc.)
We don’t have your full code to give exact advise, but you may want to rethink
