Weston Pace created ARROW-14356:
-----------------------------------

             Summary: [C++] Improve array size estimation to account for offsets
                 Key: ARROW-14356
                 URL: https://issues.apache.org/jira/browse/ARROW-14356
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: C++
            Reporter: Weston Pace


It is difficult to calculate the size (in bytes) of an array that has offsets because offsets are "# of values" there is no type-erased way to known how many bytes each value occupies.

This could be handled somewhat manually with a visitor.
