Capability	Status	Notes
Platform Instance	✅	Enabled by default

This plugin extracts Charts, dashboards, and associated metadata. This plugin is in beta and has only been tested on PostgreSQL and H2 database.

Dashboard

/api/dashboard endpoint is used to retrieve the following dashboard information.

• Title and description

• Link to the dashboard in Metabase
• Associated charts

Chart

/api/card endpoint is used to retrieve the following information.

• Title and description

• Link to the chart in Metabase
• Datasource and lineage

The following properties for a chart are ingested in DataHub.

Name	Description
Dimensions	Column names
Filters	Any filters applied to the chart
Metrics	All columns that are being used for aggregation

CLI based Ingestion

Install the Plugin

pip install 'acryl-datahub[metabase]'

database_id_to_instance_map map(str,string)
default_schema string	Default schema name to use when schema is not provided in an SQL query Default: public
engine_platform_map map(str,string)
password string(password)	Metabase password.
platform_instance_map map(str,string)
username string	Metabase username.
env string	The environment that all assets produced by this connector belong to Default: PROD

Metabase databases will be mapped to a DataHub platform based on the engine listed in the api/database response. This mapping can be customized by using the engine_platform_map config option. For example, to map databases using the athena engine to the underlying datasets in the glue platform, the following snippet can be used:

  engine_platform_map:
    athena: glue

DataHub will try to determine database name from Metabase api/database payload. However, the name can be overridden from database_alias_map for a given database connected to Metabase.

If several platform instances with the same platform (e.g. from several distinct clickhouse clusters) are present in DataHub, the mapping between database id in Metabase and platform instance in DataHub may be configured with the following map:

  database_id_to_instance_map:
    "42": platform_instance_in_datahub

The key in this map must be string, not integer although Metabase API provides id as number. If database_id_to_instance_map is not specified, platform_instance_map is used for platform instance mapping. If none of the above are specified, platform instance is not used when constructing urn when searching for dataset relations.
