README.md

Hello, world! 👋

We've rebuilt data engineering for the data science era.

Prefect is a new workflow management system, designed for modern infrastructure and powered by the open-source Prefect Core workflow engine. Users organize Tasks into Flows, and Prefect takes care of the rest.

Read the docs; get the code; ask us anything!

from prefect import task, Flow


@task
def say_hello():
    print("Hello, world!")


with Flow("My First Flow") as flow:
    say_hello()


flow.run() # "Hello, world!"

Docs

Prefect's documentation -- including concepts, tutorials, and a full API reference -- is always available at docs.prefect.io.

Contributing

Prefect is committed to ensuring a positive environment. All interactions are governed by our Code of Conduct.

"...Prefect?"

From the Latin praefectus, meaning "one who is in charge", a prefect is an official who oversees a domain and makes sure that the rules are followed. Similarly, Prefect is responsible for making sure that workflows execute properly.

It also happens to be the name of a roving researcher for that wholly remarkable book, The Hitchhiker's Guide to the Galaxy.
