What is gevent?¶
gevent is acoroutine -basedPython networking library that usesgreenlet to provide a high-level synchronous API on top of thelibevorlibuv event loop.
Features include:
Lightweight execution units based on greenlets.
API that re-uses concepts from the Python standard library (forexamples there areevents andqueues).
Cooperative DNS queries performed through a threadpool,dnspython, or c-ares.
Monkey patching utility to get 3rd party modules to become cooperative
TCP/UDP/HTTP servers
Subprocess support (throughgevent.subprocess)
Thread pools
gevent isinspired by eventlet but features a more consistent API,simpler implementation and better performance. Read why othersusegevent and check out the list of theopen source projects based ongevent.
gevent was written byDenis Bilenko.
Since version 1.1, gevent is maintained by Jason Madden forNextThought (through gevent 21) andInstitutional Shareholder Serviceswith help from thecontributors and islicensed under the MIT license.
