Advanced scheduling framework
The engine to power your Python apps
What is it?
Rocketry is a modern statement-based scheduling framework for Python. It is simple, clean and extensive. It is suitable for small and big projects.
This is how it looks like:
from rocketry import Rocketry from rocketry.conds import daily app = Rocketry() @app.task(daily) def do_daily(): ... if __name__ == '__main__': app.run()
- Powerful scheduling
- Concurrency (async, threading, multiprocess)
- Task pipelining
- Modifiable session also in runtime
- Async support
- Documentation: https://rocketry.readthedocs.io
- Source code: https://github.com/Miksus/rocketry
- Releases: https://pypi.org/project/rocketry/
Unlike the alternatives, Rocketry's scheduler is statement-based. Rocketry natively supports the same scheduling strategies as the other options, including cron and task pipelining, but it can also be arbitrarily extended using custom scheduling statements.
Here is an example of custom conditions:
from rocketry.conds import daily, time_of_week from pathlib import Path @app.cond() def file_exists(file): return Path(file).exists() @app.task(daily.after("08:00") & file_exists("myfile.csv")) def do_work(): ...
Rocketry is suitable for quick automation projects and for larger scale applications. It does not make assumptions of your project structure.
Install Rocketry from PyPI:
pip install rocketry
Here are some more examples of what it can do.
from rocketry.conds import every from rocketry.conds import hourly, daily, weekly, from rocketry.conds import time_of_day from rocketry.conds import cron @app.task(every("10 seconds")) def do_continuously(): ... @app.task(daily.after("07:00")) def do_daily_after_seven(): ... @app.task(hourly & time_of_day.between("22:00", "06:00")) def do_hourly_at_night(): ... @app.task((weekly.on("Mon") | weekly.on("Sat")) & time_of_day.after("10:00")) def do_twice_a_week_after_ten(): ... @app.task(cron("* 2 * * *")) def do_based_on_cron(): ...
from rocketry.conds import daily, after_success from rocketry.args import Return @app.task(daily.after("07:00")) def do_first(): ... return 'Hello World' @app.task(after_success(do_first)) def do_second(arg=Return('do_first')): # arg contains the value of the task do_first's return ... return 'Hello Python'
from rocketry.conds import daily @app.task(daily, execution="main") def do_unparallel(): ... @app.task(daily, execution="async") async def do_async(): ... @app.task(daily, execution="thread") def do_on_separate_thread(): ... @app.task(daily, execution="process") def do_on_separate_process(): ...
