Event based distributed computing using Redis and asyncio

Redis Events

Event based distributed computing using Redis and asyncio

Usage

Create a worker that will respond to events:

# worker.py

from redis_events import Client, Event

# Point client at Redis server
client = Client(
    host="mywebsite.com",
    port=6379,
    password="PASSWORD123"
)


@client.event("echo")  # name the event whatever you want
async def echo_example(event: Event):
    reply_event = Event(
        "echo", # this doesn't actually matter because it is a reply
        event.data  # echo the data that was in the first event
    )

    await client.send_reply(event, reply_event)

client.run()

Create a script that will push events

# send_events.py

from redis_events import Client
import asyncio

# obviously, must point to the same Redis server as the worker
client = Client(
    host="mywebsite.com",
    port=6379,
    password="PASSWORD123"
)

# Everything is async
async def send_events():
    my_event = Event(
        "echo",
        {"test": 1234}
    )

    await client.send(my_event)

    reply = await client.wait_for_reply(to=my_event, timeout=60)  # wait for a reply for up to 1 minute

    print("GOT REPLY")


asyncio.get_event_loop().run_until_complete(send_events())

Installation

pip install redis-events
