APScheduler (Advanced Python Scheduler) is a Python library for scheduling tasks with cron-style, interval, calendar-based, and one-off triggers, doubling as a job queue. It supports persistent job stores (PostgreSQL, MySQL, SQLite, MongoDB), event brokers for multi-node deployments, and both synchronous and asyncio/Trio flavors.

Use cases

• run a python function every day at 9am
• schedule cron jobs inside a python application
• queue background tasks in asyncio app
• persist scheduled jobs across restarts
• distribute scheduled tasks across multiple workers
• replace crontab with in-process scheduling

When to choose

• you need in-process task scheduling in Python with cron-like triggers
• you want persistent, shared job stores for high availability
• you need both sync and async (asyncio/Trio) support
• you want a lightweight alternative to external schedulers like Celery beat

When to avoid

• you need a full distributed task queue with retries and complex routing (consider Celery)
• you want to schedule jobs across non-Python systems
• you plan to use the v4.0 pre-release in production, as it may change incompatibly
