Welcome!

Prefect integrations for interacting with Hex.

Hex is a powerful platform for collaborative data science and analytics. For information getting started with Hex, check out Hex's quickstart guide.

The tasks within this collection were created by a code generator using Hex's OpenAPI spec.

Hex's REST API documentation can be found here.

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-hex with pip:

pip install prefect-hex

A list of available blocks in prefect-hex and their setup instructions can be found here.

Write and run a flow

Trigger a Hex project run and wait for completion

from prefect import flow
from prefect_hex import HexCredentials
from prefect_hex.project import trigger_project_run_and_wait_for_completion

@flow
def trigger_project_run_and_wait_for_completion_flow(project_id: str):
    hex_credentials = HexCredentials.load("hex-token")
    project_metadata = trigger_project_run_and_wait_for_completion(
        project_id=project_id,
        hex_credentials=hex_credentials
    )
    return project_metadata

trigger_project_run_and_wait_for_completion_flow(
    project_id="012345c6-b67c-1234-1b2c-66e4ad07b9f3"
)

Run project, get status, cancel run, and get list of projects

from prefect import flow
from prefect_hex import HexCredentials
from prefect_hex.project import (
    get_project_runs,
    run_project,
    get_run_status,
    cancel_run,
)

@flow
def example_hex_flow():
    # load stored credentials
    hex_credentials = HexCredentials.load("hex-token")

    # run project
    project_id='5a8591dd-4039-49df-9202-96385ba3eff8',
    project_run = run_project(project_id=project_id, hex_credentials=hex_credentials)

    # get status
    run_id = project_run.run_id
    project_run_status = get_run_status(
        project_id=project_id, run_id=run_id, hex_credentials=hex_credentials
    )
    print(project_run_status.run_url)

    # cancel run if needed
    cancel_run(project_id=project_id, run_id=run_id, hex_credentials=hex_credentials)

    # get list of project runs
    project_runs = get_project_runs(
        project_id=project_id, hex_credentials=hex_credentials
    )

    return project_runs

example_hex_flow()
