Create From the UI

Log in to MongoDB Atlas.

Select the Data Federation option on the left-hand navigation.

Create a federated database instance.

1. Click the Create New Federated Database dropdown.

2. Select Manual Setup.

Select the cloud provider where Atlas Data Federation will process your queries against your federated database instance.

You can select AWS or Azure. Once your federated database instance is created, you can't change the cloud provider where Atlas Data Federation processes your queries.

We recommend that you select the same cloud provider as the cloud provider that is hosting your data. Atlas Data Lake is currently only available in AWS and you must use a federated database instance hosted in the same cloud as your Data Lake dataset to query.

Type a name for your federated database instance in the Federated Database Instance Name field and click Continue.

Defaults to FederatedDatabaseInstance[n]. Once your federated database instance is created, you can't change its name.

Select the configuration method.

• For a guided experience, click Visual Editor.

• To edit the raw JSON, click JSON Editor.

Specify your Data Lake data store or online archive and configure virtual databases and virtual collections that map to your data store.

Optional: Repeat steps in the Visual Editor or JSON Editor tab above to define additional Data Lake datasets.

To add other data stores for federated queries, see:

• Create AWS Data Store From the UI or Create Azure Data Store From the UI

• Create HTTP or HTTPS Data Store From the UI

• Create Atlas Data Store From the UI

Click Save to create the federated database instance with virtual databases, collections, and views mapped to your Data Lake dataset or online archive.
