Weston Pace commented on ARROW-13338:
-------------------------------------
Given that we've already communicated removing this I think a better approach
will be to simply remove the synchronous APIs (related: ARROW-13554). This
would depend on ARROW-13542 which will provide an async dataset write (but
break the sync dataset write).

> The synchronous Scanner is not integrated with ExecPlans and doesn't offer
> better performance in any case than the asynchronous scanner, so we should
> start migrating away from the extraneous code path so it can be deprecated
> and then deleted.
