Micah Kornfield created ARROW-8493: -------------------------------------- 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
