## What it is
Rocketry is a modern statement-based scheduling framework for Python that lets you define tasks with composable scheduling conditions like cron, daily, or custom boolean expressions. It supports async, threading, and multiprocessing concurrency, task pipelining, and runtime-modifiable sessions.

## Use cases
- schedule python scripts to run daily
- run tasks every 10 seconds in python
- replace cron with python-based scheduler
- build task pipelines with dependencies
- schedule jobs with custom conditions
- automate etl jobs in python
- run async background tasks on a schedule

## When to choose
- you want cron-like scheduling expressed in pure Python
- you need custom or composable scheduling conditions beyond cron syntax
- you want a lightweight scheduler embedded in an existing Python app
- you need mixed async/thread/multiprocess task execution

## When to avoid
- you need a distributed job scheduler across many machines
- you prefer config-file-based scheduling like Airflow or Prefect
- you need a web UI for monitoring scheduled jobs
- you require long-term guaranteed maintenance - releases have stalled since late 2023

## Facets
- artifact type: library
- maturity: maintenance
- function: scheduling, workflow-automation, concurrency
- domain: developer-tools
- platform: python, cross-platform
- tags: task-scheduler, statement-based, cron-alternative, task-pipelining, async, automation, data-engineering
