Prefect Fugue Integration

This project provides the Fugue tasks, context and blocks for Prefect.

Getting Started

Python setup

Requires an installation of Python 3.7+.

We recommend using a Python virtual environment manager such as pipenv, conda or virtualenv.

These tasks are designed to work with Prefect 2.0. For more information about how to use Prefect, please refer to the Prefect documentation.

Installation

Install prefect-fugue with pip:

pip install prefect-fugue

It's also recommended to register Fugue blocks into your current Prefect workspace:

prefect block register -m prefect_fugue

Hello World

from prefect import flow
from prefect_fugue import fugue_engine, fsql


@flow
def hello_flow():
    fsql("""
    CREATE [[0]] SCHEMA a:int
    PRINT
    """)

hello_flow()


@flow
def world_flow(n, engine):
    with fugue_engine(engine):
        fsql("""
        CREATE [[0],[1]] SCHEMA a:int
        SELECT * WHERE a>0
        PRINT
        """, n=n)

world_flow(1, "duckdb")  # running using duckdb (assuming duckdb is installed)
world_flow(2, "fugue/my_databricks")  # running using my_databricks block on Prefect
