aiojobs

Jobs scheduler for managing background task (asyncio)

The library gives controlled way for scheduling background tasks for asyncio applications.

Installation

$ pip3 install aiojobs

Usage example

import asyncio
import aiojobs

async def coro(timeout):
    await asyncio.sleep(timeout)

async def main():
    scheduler = await aiojobs.create_scheduler()
    for i in range(100):
        # spawn jobs
        await scheduler.spawn(coro(i/10))

    await asyncio.sleep(5.0)
    # not all scheduled jobs are finished at the moment

    # gracefully close spawned jobs
    await scheduler.close()

asyncio.get_event_loop().run_until_complete(main())

Integration with aiohttp.web

from aiohttp import web
from aiojobs.aiohttp import setup, spawn

async def handler(request):
    await spawn(request, coro())
    return web.Response()

app = web.Application()
app.router.add_get('/', handler)
setup(app)

or just

from aiojobs.aiohttp import atomic

@atomic
async def handler(request):
    return web.Response()

Integration with sanic

from sanic import Sanic, response, views
from aiojobs.sanic import setup, spawn

async def handler(request):
    await spawn(request, coro())
    return response.json({})

app = Sanic(__name__)
app.add_route(test, '/')
setup(app)

or just

from aiojobs.sanic import atomic

@atomic
async def handler(request):
    return response.json({})


class Handler(views.HTTPMethodView):
    decorators = [atomic]

    async def get(self, request):
        return response.json({})
