[jira] [Created] (ARROW-12231) [C++][Dataset] Separate datasets backed by readers from InMemoryDataset

David Li created ARROW-12231:
--------------------------------

             Summary: [C++][Dataset] Separate datasets backed by readers from InMemoryDataset
                 Key: ARROW-12231
                 URL: https://issues.apache.org/jira/browse/ARROW-12231
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 4.0.0
            Reporter: Weston Pace
            Assignee: David Li


From ARROW-10882/[https://github.com/apache/arrow/pull/9802] 
 * Backing an InMemoryDataset with a reader is misleading. Let's split that out into a separate class.
 * Dataset scanning can then use an I/O thread for the new class.
 * Longer-term, we should interface with Python's async.
