diesel is a framework for easily writing reliable and scalable network applications in Python. It uses the greenlet library layered atop asynchronous socket I/O in Python to achieve benefits of both the threaded-style (linear, blocking-ish code flow) and evented-style (no locking, low overhead per connection) concurrency paradigms. It’s design is heavily inspired by the Erlang/OTP platform.
It contains high-quality buffering, queuing and synchronization primitives, procedure supervision and supervision trees, connection pools, seamless thread integration, and more.
An HTTP/1.1+WSGI+WebSockets implementation is included, as well as tight integration with the Flask web framework.
Other bundled protocols include MongoDB, Riak, and Redis client libraries.
