[David Li](https://issues.apache.org/jira/browse/ARROW-9773?focusedCommentId=17544576) / @lidavidm: It needs someone motivated to sit down and work through the implementation. I can review/offer suggestions but probably don't have the time to implement this right...
[Will Jones](https://issues.apache.org/jira/browse/ARROW-9773?focusedCommentId=17550684) / @wjones127: I'm interested in working on this soon. I'll look through the issue a little deeper and ping you @lidavidm to get some ideas on the design.

[Will Jones](https://issues.apache.org/jira/browse/ARROW-9773?focusedCommentId=17551259) / @wjones127: I've looked through the code and I think there are three related issues. I'll try to describe them here. If you think I am missing some...

[Gabor Szadovszky](https://issues.apache.org/jira/browse/PARQUET-1295?#comment-16470082) / @gszadovszky: I completely agree, @vrozov. Could you please explain the incompatibilities you have found? In the build process we are using `semver` to enforce the API compatibility...
[Vlad Rozov](https://issues.apache.org/jira/browse/PARQUET-1295?#comment-16471111) / @vrozov: Just as an example, there are semver incompatible changes to `org.apache.parquet.column.values.ValuesReader`.
