## What it is
arq is a Python job queuing and RPC library built on asyncio and Redis, designed as a fast, modern successor to rq. It supports deferred execution, retries, and pessimistic execution so critical jobs are not lost.

## Use cases
- run background jobs in python with asyncio
- queue tasks with redis
- retry failed jobs automatically
- distribute work across multiple workers
- replace celery or rq with something faster
- schedule deferred job execution

## When to choose
- your stack is asyncio-based and you need non-blocking job execution
- you want a small, simple, fast alternative to celery or rq
- you need reliable retries and at-least-once execution semantics

## When to avoid
- you need a feature-rich task framework with complex workflows
- you cannot use Redis as a broker
- you need a project under active feature development, since arq is in maintenance-only mode

## Facets
- artifact type: library
- maturity: maintenance
- function: message-queue, concurrency, rpc, scheduling
- domain: microservices, backend, developer-tools
- platform: python, windows
- tags: asyncio, job-queue, background-jobs, task-queue, worker-pool, msgpack, automation, redis, linux, macos
