Project description
prefect streamline
prefect_streamline is an opinionated extension that provides helpers to deploy and test Prefect flows quickly and easily.
With its deployment and testing features, you can easily ensure the quality and reliability of your workflows before deploying them.
Getting started
pip install prefect_streamline
Usage
Deploy flows using decorator
prefect_streamline
allows you to configure the deployment of flows with a decorator.
Vous pouvez définir plusieurs déploiements pour un même flow.
myapp/flow.py
from prefect import flow
from prefect_streamline import deploybook
@deploybook.register(interval=90, name="hello2")
@deploybook.register(cron="*/3 * * * *")
@deploybook.register(name="manual")
@flow(name="main.myflow")
def myflow() -> int:
return 43
the prefect-streamline cli browses all the subfolders of your application.
# deploy all the flows register into myapp/flow.py
prefect-streamline deploy myapp/flow.py
# search all flow records in all myapp modules.
prefect-streamline deploy --discover src/myapp
Accelerate flow testing using native python invocation
from prefect_streamline import flowtest
def test_test_flow_should_handle_the_logger():
with flowtest.use_native_runner():
assert flowtest.fn(myflow)() == 12
@flow()
def myflow() -> int:
logger = get_run_logger()
return 12
