redis-ipc 0.2.1

A minimal multi producer single consumer IPC using redis pub/sub

Redis IPC

A lightweight multiple producer and single consumer IPC server that uses redis pubsub as a broker

Creates a redis ipc server that listens on a single pub/sub channel and allows you to communicate between multiple processes

Subclass the IPC class and add your handlers as methods like this (handlers must start with handle_ as their name)

async def handle_channel_update(self, data):
    return data

or use IPC.add_handler to add the handler after the class has been instantiated

and whenever a process calls IPC.get, all the clients connected to that channel will try to handle the request and whichever one finishes first, will be returned by the function

the handler must either return a dict or None None is treated as an implicit reason that the current process doesn't matches the requests' target process
