# Dagster

In this section, we provide guides and references to use the Dagster connector.

Configure and schedule Dagster metadata and profiler workflows from the OpenMetadata UI:

- [Dagster](#dagster)
  - [Requirements](#requirements)
    - [Dagster Versions](#dagster-versions)
  - [Metadata Ingestion](#metadata-ingestion)
      - [Service Name](#service-name)
      - [Connection Options](#connection-options)
      - [Metadata Ingestion Options](#metadata-ingestion-options)
  - [Troubleshooting](#troubleshooting)
    - [Workflow Deployment Error](#workflow-deployment-error)

If you don't want to use the OpenMetadata Ingestion container to configure the workflows via the UI, then you can check
the following docs to connect using Airflow SDK or with the CLI.

## Requirements

{%inlineCallout icon="description" bold="OpenMetadata 0.12 or later" href="/deployment"%}
To deploy OpenMetadata, check the Deployment guides. 
{% /inlineCallout %}

To run the Ingestion via the UI you'll need to use the OpenMetadata Ingestion Container, which comes shipped with
custom Airflow plugins to handle the workflow deployment.

### Dagster Versions

OpenMetadata is integrated with dagster upto version [1.0.13](https://docs.dagster.io/getting-started) and will continue to work for future dagster versions.

The ingestion framework uses [dagster graphql python client](https://docs.dagster.io/_apidocs/libraries/dagster-graphql#dagster_graphql.DagsterGraphQLClient) to connect to the dagster instance and perform the API calls

## Metadata Ingestion

{% stepsContainer %}

{% step srNumber=1 %}

{% stepDescription title="1. Visit the Services Page" %}

The first step is ingesting the metadata from your sources. Under
Settings, you will find a Services link an external source system to
OpenMetadata. Once a service is created, it can be used to configure
metadata, usage, and profiler workflows.

To visit the Services page, select Services from the Settings menu.

{% /stepVisualInfo %}

{% /step %}

{% step srNumber=2 %}

{% stepDescription title="2. Create a New Service" %}

Click on the 'Add New Service' button to start the Service creation.

{% /stepVisualInfo %}

{% /step %}



{% step srNumber=3 %}

{% stepDescription title="3. Select the Service Type" %}

Select Dagster as the service type and click Next.

{% /stepDescription %}

{% stepVisualInfo %}

{% /stepVisualInfo %}

{% /step %}

{% step srNumber=4 %}

{% stepDescription title="4. Name and Describe your Service" %}

Provide a name and description for your service as illustrated below.

#### Service Name

OpenMetadata uniquely identifies services by their Service Name. Provide
a name that distinguishes your deployment from other services, including
the other {connector} services that you might be ingesting metadata
from.

{% /stepVisualInfo %}

{% /step %}

{% step srNumber=5 %}

{% stepDescription title="5. Configure the Service Connection" %}

In this step, we will configure the connection settings required for
this connector. Please follow the instructions below to ensure that
you've configured the connector to read from your dagster service as
desired.

{% /step %}

{% extraContent parentTagName="stepsContainer" %}

#### Connection Options

- **Host**: Host of the dagster eg.`https://localhost:300` or `https://127.0.0.1:3000` or `https://<yourorghere>.dagster.cloud/prod`
- **Token** : Need pass token if connecting to `dagster cloud` instance
  - Log in to your Dagster account.
  - Click on the "Settings" link in the top navigation bar.
  - Click on the "API Keys" tab.
  - Click on the "Create a New API Key" button.
  - Give your API key a name and click on the "Create API Key" button.
  - Copy the generated API key to your clipboard and paste it in the field.

{% /step %}

{% step srNumber=7 %}

{% stepDescription title="7. Configure Metadata Ingestion" %}

In this step we will configure the metadata ingestion pipeline,
Please follow the instructions below

{% /step %}

{% extraContent parentTagName="stepsContainer" %}

#### Metadata Ingestion Options

- **Name**: This field refers to the name of ingestion pipeline, you can customize the name or use the generated name.
- **Pipeline Filter Pattern (Optional)**: Use to pipeline filter patterns to control whether or not to include pipeline as part of metadata ingestion.
  - **Include**: Explicitly include pipeline by adding a list of comma-separated regular expressions to the Include field. OpenMetadata will include all pipeline with names matching one or more of the supplied regular expressions. All other schemas will be excluded.
  - **Exclude**: Explicitly exclude pipeline by adding a list of comma-separated regular expressions to the Exclude field. OpenMetadata will exclude all pipeline with names matching one or more of the supplied regular expressions. All other schemas will be included.
- **Include lineage (toggle)**: Set the Include lineage toggle to control whether or not to include lineage between pipelines and data sources as part of metadata ingestion.
- **Enable Debug Log (toggle)**: Set the Enable Debug Log toggle to set the default log level to debug, these logs can be viewed later in Airflow.
- **Mark Deleted Pipelines (toggle)**: Set the Mark Deleted Pipelines toggle to flag pipelines as soft-deleted if they are not present anymore in the source system.

{% step srNumber=8 %}

{% stepDescription title="8. Schedule the Ingestion and Deploy" %}

Scheduling can be set up at an hourly, daily, weekly, or manual cadence. The
timezone is in UTC. Select a Start Date to schedule for ingestion. It is
optional to add an End Date.

Review your configuration settings. If they match what you intended,
click Deploy to create the service and schedule metadata ingestion.

If something doesn't look right, click the Back button to return to the
appropriate step and change the settings as needed.

After configuring the workflow, you can click on Deploy to create the
pipeline.

## Troubleshooting

### Workflow Deployment Error

If there were any errors during the workflow deployment process, the
Ingestion Pipeline Entity will still be created, but no workflow will be
present in the Ingestion container.

- You can then edit the Ingestion Pipeline and Deploy it again.

- From the Connection tab, you can also Edit the Service if needed.
