Prefect 2.0
A development repo for Prefect 2.0. Documentation can be found at https://orion-docs.prefect.io/.
Welcome!
Prefect 2.0 is the second-generation workflow orchestration platform from Prefect.
Prefect 2.0 has been designed from the ground up to handle the dynamic, scalable workloads that the modern data stack demands. Powered by Orion, a brand-new, asynchronous rules engine, it represents an enormous amount of research, development, and dedication to a simple idea:
You should love your workflows again.
Read the docs, run the code, or host the UI. Join thousands of community members in our Slack community to share your thoughts and feedback. Thanks for being part of the mission to build a new kind of workflow system and, of course, happy engineering!
"Don't Panic"
Prefect 2.0 and Orion are beta software under active development and may change rapidly. For production use, we recommend Prefect 1.0.
Hello, Orion!
Powered by the Orion engine, Prefect is the easiest way to transform any function into a unit of work that can be observed and governed by orchestration rules.
Add workflow features like retries, distributed execution, scheduling, caching, and much more, with minimal changes to your code. Every activity is tracked and becomes visible in the Orion Dashboard.
from prefect import flow, task
from typing import List
import httpx
@task(retries=3)
def get_stars(repo: str):
url = f"https://api.github.com/repos/{repo}"
count = httpx.get(url).json()["stargazers_count"]
print(f"{repo} has {count} stars!")
@flow(name="GitHub Stars")
def github_stars(repos: List[str]):
for repo in repos:
get_stars(repo)
# run the flow!
github_stars(["PrefectHQ/Prefect", "PrefectHQ/miter-design"])
After running any running some flows, fire up the UI to gain insight into their execution:
prefect orion start
From here, you can continue to use Prefect interactively or set up automated deployments.
Next steps
Prefect 2.0 was designed to be incrementally adopted into your workflows, and our documentation is organized to support your exploration as much as possible. It is organized into four main sections whose applicability will depend on your objectives and comfort level.
Getting started
Begin by installing Prefect on your machine, then follow one of our friendly tutorials to learn by example. See the Getting Started overview for more.
Concepts
Learn more about Prefect's features and design by reading our in-depth concept docs. These are intended to introduce the building blocks of Prefect, build up to orchestration and deployment, and finally cover some of the advanced use cases that Prefect makes possible.
Frequently asked questions
Prefect 2.0 represents a fundamentally new way of building and orchestrating data workflows. Learn more about the project by reading our FAQ.
API reference
Prefect provides a number of programmatic workflow interfaces, each of which is documented in the API Reference. This is where you can learn how a specific function works, or see the expected payload for a REST endpoint.
