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.


Pulsar’s codebase is relatively small, at about 20,000 lines of code. The source code is open and it has a very liberal license. You can fork the code add feature you need and send us your patch.


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 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 examples module of the distribution directory.
