.. _pulsar-advantage: Pulsar Advantage ======================== Python 3 - Asyncio -------------------- Pulsar is written in python 3 and it is built on top of asyncio_, the new asynchronous module in the python standard library. Flexibility ------------------- Pulsar's codebase is relatively small, at about 20,000 lines of code. The source code is open and it has a very :ref:`liberal license `. You can :ref:`fork the code ` add feature you need and send us your patch. Multiprocessing ------------------- Multiprocessing is the default parallel execution mechanism, therefore each pulsar components have been designed in a share nothing architecture. Communication between workers is obtained via tcp sockets which :ref:`exchange messages ` using the websocket protocol. You can also run workers in threading mode. Documented and Samples --------------------------- Pulsar documentation is continuously updated and extended and there are several examples in the :mod:`examples` module of the distribution directory. .. _asyncio: http://python.readthedocs.org/en/latest/library/asyncio.html
