Taskiq NATS

Taskiq-nats is a plugin for taskiq that adds NATS broker.

Installation

To use this project you must have installed core taskiq library:

Usage

Here's a minimal setup example with a broker and one task.

import asyncio
from taskiq_nats import NatsBroker

broker = NatsBroker(
    [
        "nats://nats1:4222",
        "nats://nats2:4222",
    ],
    queue="random_queue_name",
)


@broker.task
async def my_lovely_task():
    print("I love taskiq")


async def main():
    await broker.startup()

    await my_lovely_task.kiq()

    await broker.shutdown()


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

NatsBroker configuration

Here's the constructor parameters:

• servers - a single string or a list of strings with nats nodes addresses.
• subject - name of the subect that will be used to exchange tasks betwee workers and clients.
• queue - optional name of the queue. By default NatsBroker broadcasts task to all workers, but if you want to handle every task only once, you need to supply this argument.
• result_backend - custom result backend.
• task_id_generator - custom function to generate task ids.
• Every other keyword argument will be sent to nats.connect function.
