Weston Pace created ARROW-14355:
-----------------------------------
Summary: [C++] Create naive implementation of algorithm to
estimate table/batch buffer size
Key: ARROW-14355
URL: https://issues.apache.org/jira/browse/ARROW-14355
Project: Apache Arrow
Issue Type: Sub-task
Components: C++
Reporter: Weston Pace
This will simply sum up all of the buffers. It will overestimate in a few
cases:
* If there are offsets it will overestimate
* If there are shared buffers it will overestimate
It only measures the size of the buffers and will not consider the control data
(e.g. the C objects wrapping the data) or, specifically for ExecBatch, it will
not count scalars.
