Joris Van den Bossche commented on ARROW-12203:
-----------------------------------------------
The {{version="2.0"}} could be an alias of "latest 2.x" version with all
features. That's of course also confusing (since 2.0 is also an explicit
version, and which is lower than the 2.4 or 2.5), but IMO less confusing than
having a "1.9" which is 1) a non-existing version and 2) enabling 2.x features.

> Key: ARROW-12203
> URL: https://issues.apache.org/jira/browse/ARROW-12203
> 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.
