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

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

Ingestion Deployment

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. If you want to install it manually in an already existing Airflow host, you can follow this guide.

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 run the Ingestion Framework in any orchestrator externally.

Requirements

The ingestion also works with Superset 2.0.0 🎉

API Connection: To extract metadata from Superset via API, user must have at least can read on Chart & can read on Dashboard permissions.

Database Connection: To extract metadata from Superset via MySQL or Postgres database, database user must have at least SELECT privilege on dashboards & slices tables within superset schema.

Metadata Ingestion

1. Visit the Services Page

Click Settings in the side navigation bar and then Services.

The first step is to ingest the metadata from your sources. To do that, you first need to create a Service connection first.

This Service will be the bridge between OpenMetadata and your source system.

Once a Service is created, it can be used to configure your ingestion workflows.

Visit Services Page

Select your Service Type and Add a New Service

2. Create a New Service

Click on Add New Service to start the Service creation.

Create a new Service

Add a new Service from the Services page

3. Select the Service Type

Select Superset as the Service type and click Next.

Select Service

Select your Service from the list

4. Name and Describe your Service

Provide a name and description for your Service.

Service Name

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

Note that when the name is set, it cannot be changed.

Add New Service

Provide a Name and description for your Service

5. Configure the Service Connection

In this step, we will configure the connection settings required for Superset.

Please follow the instructions below to properly configure the Service to read from your sources. You will also find helper documentation on the right-hand side panel in the UI.

Configure Service connection

Configure the Service connection by filling the form

Connection Details

  • Host and Port: The Host and Post parameter is common for all three modes of authentication which specifies the host and port of the Superset instance. This should be specified as a string in the format http://hostname:port or https://hostname:port. For example, you might set the hostPort parameter to https://org.superset.com:8088.

  • Superset Connection: Add the connection details to fetch metadata from Superset either through APIs or Database.

For Superset API Connection

Superset API connection is the default mode of authentication where we fetch the metadata using Superset APIs.

  • Username: Username to connect to Superset, for ex. user@organization.com. This user should have access to relevant dashboards and charts in Superset to fetch the metadata.

  • Password: Password of the user account to connect with Superset.

  • Provider: Choose between db(default) or ldap mode of Authentication provider for the Superset service. This parameter is used internally to connect to Superset's REST API.

  • Verify SSL: Client SSL verification. Make sure to configure the SSLConfig if enabled. Possible values:

    • validate: Validate the certificate using the public certificate (recommended).
    • ignore: Ignore the certification validation (not recommended for production).
    • no-ssl: SSL validation is not needed.

  • SSL Config: Client SSL configuration in case we are connection to a host with SSL enabled.

  • Certificate Path: CA certificate path in the instance where the ingestion run. E.g., /path/to/public.cert. Will be used if Verify SSL is set to validate.

For MySQL Connection

You can use Mysql Connection when you have SSO enabled and your Superset is backed by Mysql database.

  • Username: Specify the User to connect to MySQL. It should have enough privileges to read all the metadata. Make sure the user has select privileges on dashboards, tables & slices tables of superset schema.
  • Password: Password to connect to MySQL.
  • Host and Port: Enter the fully qualified hostname and port number for your MySQL deployment in the Host and Port field.
  • databaseSchema: Enter the database schema which is associated with the Superset instance.
  • caCertificate: Provide the path to ssl ca file.
  • sslCertificate: Provide the path to ssl client certificate file (ssl_cert).
  • sslKey: Provide the path to ssl client certificate file (ssl_key).

Advanced Configuration

Database Services have an Advanced Configuration section, where you can pass extra arguments to the connector and, if needed, change the connection Scheme.

This would only be required to handle advanced connectivity scenarios or customizations.

  • Connection Options (Optional): Enter the details for any additional connection options that can be sent to database during the connection. These details must be added as Key-Value pairs.
  • Connection Arguments (Optional): Enter the details for any additional connection arguments such as security or protocol configs that can be sent during the connection. These details must be added as Key-Value pairs.

For Postgres Connection

You can use Postgres Connection when you have SSO enabled and your Superset is backed by Postgres database.

  • Username: Specify the User to connect to Postgres. Make sure the user has select privileges on dashboards, tables & slices tables of superset schema.
  • Password: Password to connect to Postgres.
  • Host and Port: Enter the fully qualified hostname and port number for your Postgres deployment in the Host and Port field.
  • Database: Initial Postgres database to connect to. Specify the name of database associated with Superset instance.
  • caCertificate: Provide the path to ssl ca file.

Securing Superset Connection with SSL in OpenMetadata

  1. To establish secure connections between OpenMetadata and Superset, navigate to the Advanced Config section. We need to update the Certificate Path and ensure that the certificates are accessible from the Airflow Server.
Supertset API SSL Configuration

SSL Configuration

  1. To establish secure connections between OpenMetadata and Superset's MySQL database, you need to configure SSL certificates appropriately. If you only require SSL validation, specify the caCertificate to use the CA certificate for validating the server's certificate. For mutual authentication, where both client and server need to authenticate each other, you must provide all three parameters: ssl_key for the client’s private key, ssl_cert for the client’s SSL certificate, and ssl_ca for the CA certificate to validate the server’s certificate.
MySQL SSL Configuration

SSL Configuration

  1. To establish secure connections between OpenMetadata and Superset's PostgreSQL database, you can configure SSL using different SSL modes provided by PostgreSQL, each offering varying levels of security.Under PostgresConnection Advanced Config, specify the SSL mode appropriate for your connection, such as prefer, verify-ca, allow, and others. After selecting the SSL mode, provide the CA certificate used for SSL validation (caCertificate). Note that PostgreSQL requires only the CA certificate for SSL validation.
