[jira] [Created] (ARROW-2759) Timeout for `get_next_notification()`
in Plasma
Siyuan Zhuang created ARROW-2759:
------------------------------------
Summary: Timeout for `get_next_notification()` in Plasma
Key: ARROW-2759
URL: https://issues.apache.org/jira/browse/ARROW-2759
Project: Apache Arrow
Issue Type: Improvement
Components: Plasma (C++), Python
Reporter: Siyuan Zhuang
Currently, I am implementing an async interface for Ray. The implementation needs some kind of message polling methods like `get_next_notification`.
Unfortunately, I find `get_next_notification` in `https://github.com/apache/arrow/blob/master/python/pyarrow/_plasma.pyx` blocking, which is an impediment to implementing async utilities. So I suggest adding some parameters like `timeout`. It could be done by operating its underlying socket.
