Metabase databases will be mapped to a DataHub platform based on the engine listed in the
[api/database](https://www.metabase.com/docs/latest/api-documentation.html#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:
```yml
  engine_platform_map:
    athena: glue
```
DataHub will try to determine database name from Metabase [api/database](https://www.metabase.com/docs/latest/api-documentation.html#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:
```yml
  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.
