gevent compatibility layer for pyzmq
Project description
Wrapper of pyzmq to make it compatible with gevent. 0MQ socket operations that would normally block the current thread will only block the current greenlet.
Inspired by Ben Ford’s work on 0MQ support in eventlet.
Requirements
Requires pyzmq>=2.1.0
Before version 2.1.0 (of both 0MQ and pyzmq) the underlying file descriptors that this library utilizes were not available.
Usage
Instead of importing zmq directly do a:
from gevent_zeromq import zmq
And use as normal.
About
This compatibility is accomplished by ensuring the nonblocking flag is set before any blocking operation and the 0MQ file descriptor is polled internally to trigger needed events.
Will build with cython if available. In my simple nonscientific test this resulted in an almost 50% speedup in a local 1-1 PUB SUB sending of 100,000 1K messages in a single tight loop.
There are plans to further the integration with both gevent and pyzmq via cython for speed.
