[jira] [Updated] (ARROW-12231) [C++][Dataset] Separate datasets
backed by readers from InMemoryDataset
[ https://issues.apache.org/jira/browse/ARROW-12231?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Li updated ARROW-12231:
-----------------------------
Description:
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. (Note that for Python, we'll need to be careful to release the GIL before any operations so that the I/O thread can acquire the GIL to call into the underlying Python reader/file object.)
* Longer-term, we should interface with Python's async.
