Micah Kornfield updated ARROW-8493:
-----------------------------------
Description: Augment SchemaField in SchemaManifest to track repeated
ancestor definition level. (was: We need a function/class that can take the
parquet schema and a proposed arrow schema (potentially retrieved from parquet
metadata) and outputs a data structure that contains, all of the information in
"SchemaField" and the following additional options:
1. Corresponding Definition level for nullability (wouldn't be populated for
non-null arrays).
2. Correspond Repetition level for lists (wouldn't be populated for for
non-lists).
3. Definition level for "empty lists". (wouldn't be populated for legacy two
level encoded lists).
One option is to augment and populate these on the SchemaField.)
> [C++] Create unified schema resolution code for Array reconstruction.
