Review comment:
@HyukjinKwon, no, I meant I'd rather work on the name together to make
sure it is good enough rather than revert the change. Here is a quote from my
earlier comment:
> I'd fix the name and cherry-pick it to 3.1 rather than revert the change
completely.
I think we are on the same page here and I'll fix the name as part of
SPARK-33784. Thanks for creating it, btw!
Currently proposed names are:
- `postOperatorOptimizationRules`
- `preCostBasedOptimizationRules`
- `preCBORules`
What does everybody think about them? Any preferences?
