Micah Kornfield commented on ARROW-12203:
-----------------------------------------
I think switches like this should follow a policy similar to API deprecation.
i.e. something like we put in release notes that we intend to switch the
default version (maybe for more then one release) and then make the change in
some subsequent release. It might be worth an ML discussion on policy around
this.
Thank you for the analysis. Based upon it, I would suggest maybe instead of
1.9 we try to make this value correspond with release (introduce a 2.3 and and
2.5) if we don't think it will make the code to horrendous.

> Project: Apache Arrow
> Issue Type: Wish
> Components: C++, Python
> Reporter: Antoine Pitrou
> Priority: Major
> Fix For: 4.0.0

>
> Currently, Parquet write APIs default to maximum-compatibility Parquet
> version "1.0", which disables some logical types such as UINT32. We may want
> to switch the default to "2.0" instead, to allow faithful representation of
> more types.
