Deploy a Federated Database Instance

Log in to MongoDB Atlas.

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

Create a federated database instance.

• For your first federated database instance, click Create a Federated Database.

• For subsequent federated database instances, click Create Federated Database.

Select the dataset for you federated database instance from the Data Sources section.

Select AWS S3 from the dropdown and click Add Sample Data to use the MongoDB hosted sample dataset.

Drag and drop the following paths to the sample datasets from the Data Sources pane on the left to the Federated Database Instance pane on the right.

• /airbnb/listingsAndReviews/{bedrooms string}/{review_scores.review_scores_rating int}/

  This path references the airbnb dataset, which contains the vacation home listing details and customer reviews. To learn more about this dataset, see Sample AirBnB Listings Dataset.

  For this path, federated database instance utilizes partitions optimized for queries on the bedrooms field and review_scores.review_score_ratings fields.

• /analytics/accounts/{limit int}/

  This path references the analytics dataset, which contains data for a typical finanacial services application. To learn more about this dataset, see Sample Analytics Dataset.

  For this path, federated database instance utilizes partitions optimized for queries on the limit field.

• /analytics/customers/{birthdate isodate}/

  This data references the analytics dataset, which contains collections for a typical finanacial services application. To learn more about this dataset, see Sample Analytics Dataset.

  For this path, federated database instance utilizes partitions optimized for queries on the birthdate field.

• /analytics/transactions/{account_id int}/

  This path references the analytics dataset, which contains data for a typical finanacial services application. To learn more about this dataset, see Sample Analytics Dataset.

  For this path, federated database instance utilizes partitions optimized for queries on the account_id field.

• /mflix/movies/{type string}/{year int}/

  This path references the mflix dataset, which contains data on movies and movie theaters. To learn more about this dataset, see Sample Mflix Dataset.

  For this path, federated database instance utilizes partitions optimized for queries on the type and year fields.

• /mflix/sessions.json

  This path references the mflix dataset, which contains data on movies and movie theaters. To learn more about this dataset, see Sample Mflix Dataset.

  This path does not contain any partition attributes and so, for queries against data in the collection, Data Federation searches all the files in the collection.

• /mflix/theaters/{theaterId string}/{location.address.zipcode string}/

  This path references the mflix dataset, which contains data on movies and movie theaters. To learn more about this dataset, see Sample Mflix Dataset.

  For this path, federated database instance utilizes partitions optimized for queries on the theaterId and location.address.zipcode fields.

• /mflix/users.json

  This path references the mflix collection, which contains data on movies and movie theaters. To learn more about this dataset, see Sample Mflix Dataset.

  This path does not contain any partition attributes and so, for queries against data in the collection, federated database instance searches all the files in the collection.

• /nyc-yellow-cab-trips/{trip_start_isodate isodate}/{passenger_count int}/{fare_type string}/

  The path references the nyc-yellow-cab-trips dataset, which contains data on the trips, including trip date, fare, and number of passengers.

  For this path, federated database instance utilizes partitions optimized for queries on the trip_start_isodate, passenger_count, and fare_type fields.

Optional: Change the name of the federated database instance from FederatedDatabaseInstance0 to GettingStarted by clicking the associated icon.

You need not modify the database or collection name because the sample queries that you run against the sample datasets later in this tutorial use the default names.

Click Save to create the federated database instance.
