The way I've always interpreted the encodings on the writer's side is that any fallback (or series of fallbacks) should be considered valid, even though that isn't as the spec reads, and there are probably other edge cases to consider as well. - https://issues.apache.org/jira/browse/PARQUET-2222: RLE encoding spec > incorrect for v2 data pages This seems more serious if the encodings actually differ based on which version of the data page is used. V2 (especially in C++) has never really been production ready, We should try to resolve this bug one way or another but I think the way forward probably depends on what various implementations are doing here.
