[jira] [Created] (ARROW-9810) [C++][Parquet] Generalize existing null bitmap generation

Micah Kornfield created ARROW-9810:
--------------------------------------

             Summary: [C++][Parquet] Generalize existing null bitmap generation 
                 Key: ARROW-9810
                 URL: https://issues.apache.org/jira/browse/ARROW-9810
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: C++
            Reporter: Micah Kornfield
            Assignee: Micah Kornfield


Right now null bitmap generation assumes only list nesting.  Generalize and refactor exisitn code without changing existing functionality to accept additional parameters to support arrow nested types:

 

1.  Repeated ancestor def level

2.  Null slot usage (for fixed size lists)
