Thanks Antoine.
Do we need to hold a vote to adopt the C API? I will see if I can

hi folks,
I recently merged https://github.com/apache/arrow/pull/4826 containing
the bulk of the Parquet C++ encrypted file implementation:

There are a few open PRs that I think could either use a first or second
set of eyes:
https://github.com/apache/arrow/pull/5630
https://github.com/apache/arrow/pull/5645
https://github.com/apache/arrow/pull/5751
Would some committers be willing to take a look?
Thanks,
Micah
I think the main sticking point was dictionaries in the file format. It
seems like the use-case for delta dictionaries might be limited so I didn't
feel strongly about it.
Antoine, did you have more thoughts on this?
Thanks,
Micah

Bumping this discussion since a couple of weeks have passed. It seems
there are still some questions here, could we summarize what are the
alternatives along with any public API implications so we can try to
render a decision?
