--------------------------------------
Summary: [C++] Create unified schema resolution code for Array reconstruction.
Key: ARROW-8493
URL: https://issues.apache.org/jira/browse/ARROW-8493
Project: Apache Arrow
Issue Type: Sub-task
Components: C++
Reporter: Micah Kornfield
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).
One option is to augment and populate these on the SchemaField.
