BSPump: A real-time stream processor for Python 3.5+

BSPump: A real-time stream processor for Python 3.5+

Principles

• Write once, use many times
• Schema-less
• High performance
• Back pressure
• Simple to use and well documented, so anyone can write their own stream processor
• Sliding time window
• Asynchronous via Python 3.5+ async/await and asyncio
• Event driven Architecture / Reactor pattern
• Single-threaded core but compatible with threads
• Compatible with pypy, Just-In-Time compiler capable of boosting Python code performace more then 5x times
• Modularized

Stream processor example

#!/usr/bin/env python3
import bspump
import bspump.socket
import bspump.common
import bspump.elasticsearch

class MyPipeline(bspump.Pipeline):
    def __init__(self, app):
        super().__init__(app)
        self.build(
            bspump.socket.TCPStreamSource(app, self),
            bspump.common.JSONParserProcessor(app, self),
            bspump.elasticsearch.ElasticSearchSink(app, self, "ESConnection")
        )


if __name__ == '__main__':
    app = bspump.BSPumpApplication()
    svc = app.get_service("bspump.PumpService")
    svc.add_connection(bspump.elasticsearch.ElasticSearchConnection(app, "ESConnection"))
    svc.add_pipeline(MyPipeline(app))
    app.run()
