A tiny peer-to-peer data-streaming library

Project description

# simplestreamer

This is a tiny (< 150 loc) peer-to-peer data-streaming library designed for high-frequency status data. It uses pickle underneath to serialize the data, so you can dump any python object through it.

You can install it with pip install simplestreamer

Here is a quick example of how to use it. Hopefully it is self-explanatory enough.

node 1 code:

# just dumps time data into the streamer at 100 hz
import simplestreamer
import time

streamer = simplestreamer.SimpleStreamer(5200)

while True:
    streamer.send_data({"current time.time()": time.time()})
    time.sleep(0.01)

node 2 (and 3, and 4, and so on) code:

# subscribes to the stream from node 1 and periodically reads the data
import simplestreamer
import time

streamer = simplestreamer.SimpleStreamer(5201)
streamer.subscribe("127.0.0.1", 5200, "streamer 1")
# You can optionally configure the rate at which the remote streamer sends you data
#streamer.subscribe("127.0.0.1", 5200, "streamer 1", updates_per_sec=1.5)

while True:
    print(streamer.get_data("streamer 1"))
    time.sleep(0.5)
