About this integration

Including Hex in your Dagster data pipelines and orchestration workflows lets you do things like:

• Trigger a Hex app to update cached values after an upstream transformation completes
• Run a Hex project with passed-in input parameters based on a form submission in another app
• Automatically kick off a model re-run through Hex when new source data lands

With this integration, you can call the Hex API to run a project until it completes. Dagster Ops can return an AssetMaterialization of a Hex dataset.

Installation

pip install dagster-hex

Example

from dagster_hex.resources import hex_resource
from dagster import job
from dagster_hex.ops import hex_project_op

API_KEY = 'abc123'
PROJ_ID = 'i-love-uuids'

my_resource = hex_resource.configured({'api_key': API_KEY})
run_hex_op = hex_project_op.configured(
    {"project_id": PROJ_ID},
    name='run_job'
)

@job(resource_defs={"hex": my_resource})
def hex_job():
    run_hex_op()

About Hex

The Dagster Hex library lets Dagster users easily add Hex apps as assets in Dagster pipelines, executing runs of or accessing metadata about Hex apps in response to upstream events and triggers.
