Run Redash using the metadata CLI
In this section, we provide guides and references to use the Redash connector.
Configure and schedule Redash metadata and profiler workflows from the OpenMetadata UI:
RequirementsOpenMetadata 0.12 or later
To deploy OpenMetadata, check the Deployment guides.
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.
To run the Redash ingestion, you will need to install:
All connectors are defined as JSON Schemas. Here you can find the structure to create a connection to Redash.
In order to create and run a Metadata Ingestion workflow, we will follow the steps to create a YAML configuration able to connect to the source, process the Entities if needed, and reach the OpenMetadata server.
The workflow is modeled around the following JSON Schema
1. Define the YAML Config
Source Configuration - Service Connection
hostPort: URL to the Redash instance.
username: Specify the User to connect to Redash. It should have enough privileges to read all the metadata.
apiKey: API key of the redash instance to access. It has the same permissions as the user who owns it. Can be found on a user profile page.
Redash Version: Redash version of your redash instance. Enter the numerical value from the Redash Releases page. Default:
Source Configuration - Source Config
sourceConfig is defined here:
- dbServiceNames: Database Service Names for ingesting lineage if the source supports it.
- dashboardFilterPattern, chartFilterPattern, dataModelFilterPattern: Note that all of them support regex as include or exclude. E.g., "My dashboard, My dash.*, .*Dashboard".
- includeOwners: Set the 'Include Owners' toggle to control whether to include owners to the ingested entity if the owner email matches with a user stored in the OM server as part of metadata ingestion. If the ingested entity already exists and has an owner, the owner will not be overwritten.
- includeTags: Set the 'Include Tags' toggle to control whether to include tags in metadata ingestion.
- includeDataModels: Set the 'Include Data Models' toggle to control whether to include tags as part of metadata ingestion.
- markDeletedDashboards: Set the 'Mark Deleted Dashboards' toggle to flag dashboards as soft-deleted if they are not present anymore in the source system.
To send the metadata to OpenMetadata, it needs to be specified as
The main property here is the
openMetadataServerConfig, where you can define the host and security provider of your OpenMetadata installation.
For a simple, local installation using our docker containers, this looks like:
Workflow Configs for Security Provider
We support different security providers. You can find their definitions here.
Openmetadata JWT Auth
- JWT tokens will allow your clients to authenticate against the OpenMetadata server. To enable JWT Tokens, you will get more details here.
- You can refer to the JWT Troubleshooting section link for any issues in your JWT configuration. If you need information on configuring the ingestion with other security providers in your bots, you can follow this doc link.
2. Run with the CLI
First, we will need to save the YAML file. Afterward, and with all requirements installed, we can run:
Note that from connector to connector, this recipe will always be the same. By updating the YAML configuration, you will be able to extract metadata from different sources.
