Why Jobify

Most Python schedulers rely on polling loops. Jobify uses low-level asyncio timers (call_at) to schedule jobs directly.

No idle polling CPU cost
Sub-millisecond trigger precision
Native async-first execution model

If your workload is bursty or downstream services are sensitive, use Queue Middleware to add bounded buffering, backpressure, and priority routing.

Installation

pip install jobify

Quick Start

import asyncio

from jobify import Jobify, Job

app = Jobify()


@app.task
async def hello(name: str) -> None:
    print(f"Hello, {name}")


async def main() -> None:
    async with app:
        job: Job = await hello.push("Alex")
        await job.wait()


if __name__ == "__main__":
    asyncio.run(main())

Extended example (cron, delay, absolute time)

import asyncio
from datetime import datetime, timedelta
from zoneinfo import ZoneInfo

from jobify import Jobify, Job

UTC = ZoneInfo("UTC")
app = Jobify(tz=UTC)


@app.task(cron="* * * * * * *")  # every second
async def my_cron() -> None:
    print("cron tick")


@app.task
def my_job(name: str) -> None:
    now = datetime.now(tz=UTC)
    print(f"Hello, {name}! at {now!r}")


async def main() -> None:
    async with app:
        await my_job.push("Alex")

        run_next_day = datetime.now(tz=UTC) + timedelta(days=1)
        job_at: Job = await my_job.schedule("Connor").at(run_next_day)
        job_delay: Job = await my_job.schedule("Sara").delay(seconds=20)
        job_cron: Job = await my_cron.schedule().cron("* * * * *", job_id="dynamic_cron_id")

        await job_at.wait()
        await job_delay.wait()
        await job_cron.wait()


if __name__ == "__main__":
    asyncio.run(main())
