Update Data Lake Region

You can change the AWS region through which your Data Lake requests are routed. By default, Data Lake requests are routed through the region that is closest to your S3 bucket.

Note

If you change the AWS region through which your Data Lake requests are routed, you must update your Data Lake connection string with the new hostname. This change ensures that your requests are routed through the new region.

Procedure

To change the AWS region through which your Data Lake requests are routed, do the following in the Atlas UI:

1

Select Data Lake from the left-hand navigation.

2

Click Ellipses (…) to the right of the Data Lake.

Choose the region through which to route your Data Lake requests:

  • The closest available region to allow Atlas to automatically choose the Data Lake region closest to your S3 buckets.

  • A specific region to specify the region through which your Data Lake requests must be routed.

    You can select from the following regions:

    Data Lake Regions AWS Regions
    Northern Virginia, North America us-east-1
    Oregon, North America us-west-2
    Ireland, Europe eu-west-1
    London, Europe eu-west-2
    Frankfurt, Europe eu-central-1
    Sydney, Australia ap-southeast-2

Click Save for the changes to take effect.

The Data Lake hostname in your current Data Lake connection string will continue to work. However, to use the region you selected, you must update the Data Lake hostname in your Data Lake connection string. To utilize the new region, click the Connect button on your Data Lake and follow the steps in Connect to Your Data Lake.
