That indeed looks related to #2394. Reading through the issue conversation,
I also hit the error ```called `Option::unwrap()` on a `None` value```
mentioned in related #3745 (although I don't have a good repro right now).
It sounds like there isn't enough volunteer time to expand `get_row_iter()`.
Would reviewing pull requests in that code be an option? If issues can be
tackled as byte-size chunks, I can likely contribute. So far testing decoding
`REPEATED` actually looked pretty good. For instance, this non-trivial schema
seems to be handled fine (at least in the case of one repetition):
```
message schema {
REQUIRED BYTE_ARRAY value1 (UTF8);
OPTIONAL BYTE_ARRAY value2 (UTF8);
REQUIRED INT64 value3;
REPEATED group level1 {
REQUIRED BYTE_ARRAY value4 (UTF8);
OPTIONAL INT64 value5;
OPTIONAL BYTE_ARRAY value6 (UTF8);
}
}
```
Doc/example contribution could also be fair game (I was also thinking about
adding something around ObjectStore + Parquet async -- I had a hard time
figuring this one out but it actually works really well and I think I
understand that part enough now to expand the docs).
