emkornfield opened a new pull request #8376:
URL: https://github.com/apache/arrow/pull/8376
New types supported:
- Fixed Size list (will throw an incorrect error if nulls
are present, but this is best fixed after we recursively support
applying types).
- LargeList
- Maps
Still missing: LargeString and LargeBytes
Unimplemented functionality:
- Removing duplicate maps on read.
- Single column maps are converted to List of struct.
Other:
Fixed two bugs for FixedSizeLists:
1. Def levels genereated were incorrect (they only made sense for
two level lists).
2. Slices where not handled appropriately
