[jira] [Created] (ARROW-8494) [C++] Implement vectorized array reassembly logic

Micah Kornfield created ARROW-8494:
--------------------------------------

             Summary: [C++] Implement vectorized array reassembly logic
                 Key: ARROW-8494
                 URL: https://issues.apache.org/jira/browse/ARROW-8494
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: C++
            Reporter: Micah Kornfield
            Assignee: Micah Kornfield


This logic would attempt to create the data necessary for each field by passing through the levels once for each field.  it is expected that due to SIMD this will perform better for nested data with shallow nesting, but due to repetetive computation might perform worse for deep nested that include List-types.
