On this page
This page guides you through the steps for connecting to the federated database instance to query your Data Lake dataset.
Prerequisites
Before you begin, you must have the following:
An IP address added to the access list of the project that contains the cluster. To learn more, see Add Your Connection IP Address to Your IP Access List.
A database user for your cluster in the project that contains the Federated Database Instance that you want to connect to. To learn more, see Create a Database User for Your Cluster.
A Federated Database Instance on the Atlas cluster mapped to your Atlas Data Lake dataset. To learn more, see Set Up a Federated Database Instance for Your Dataset.
Procedure
Navigate to Atlas Data Federation in the Atlas UI.
To navigate to the Atlas Data Federation page:
Log in to MongoDB Atlas.
Select Data Federation under Data Services on the left-hand navigation.
Click Connect for the Federated Database Instance that you wish to connect to.
Example
If you are connecting to the Federated Database Instance for querying the Atlas Data Lake dataset that you created using the examples, click Connect for DataLake0.
Get the connection string for your preferred method of connecting.
You can connect using mongosh, a MongoDB Driver,
and MongoDB Compass. To learn how to get the
connection string for your client, click the tab below for your
connection method.
If you are following the examples in the steps for deploying an
Atlas Data Lake for the sample_mflix.movies collection and setting up
a Federated Database Instance for this Data Lake dataset, click the
MongoDB Shell tab below to connect using mongosh.
Connect your client to your Federated Database Instance using the connection string.
Next Steps
Now that you are connected to your federated database instance, proceed to Run Queries Against Your Data Lake Dataset.
