Joris Van den Bossche commented on ARROW-12203:
-----------------------------------------------
If we would enable all available logical types with a default of
{{version="2.0"}}, what do we do if the next Parquet format release adds a new
logical type? (eg if 2.10.0 adds a new Interval logical type) Maybe something
we can defer until it happens, but unless we would directly enable it, we would
then still need to add a {{version="2.10"}} option or so to enable it on
demand.

> 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.
