> Key: ARROW-3444
> URL: https://issues.apache.org/jira/browse/ARROW-3444
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Reporter: Dave Hirschfeld
> Assignee: Joris Van den Bossche

> Labels: pull-request-available

> As it says in the title, I think this would be a very handy attribute to have
> available in Python. You can get it by converting to pandas and using
> `DataFrame.nbytes` but this is wasteful of both time and memory so it would
> be good to have this information on the `pyarrow.Table` object itself.
> This could be implemented using the
> [__sizeof__|https://docs.python.org/3/library/sys.html#sys.getsizeof] protocol
