Thanks a lot for your help :)
>Can we just evaluate the right side CAST(2017 as STRING), since it is
foldable?
Do you mean to add a new rule ? -- cast the type of literal when partition
key and the literal are different types.
In current code, `StringType` are promoted(e.g. casted to `IntegerType`) in
`PromoteStrings` when it is BinaryComparison
