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.

Compatibility
