When you configure a resource on Retool Cloud, you can now choose to route traffic through the eu-central-1 region, based in Frankfurt, Germany, or through the default us-west-2 region, based in Oregon, US. This determines the network round trip time it takes Retool to query your data sources. Selecting a region in close proximity to your resources can improve your application's performance.
You can set a default region for all your resources and override it for individual resources. Learn how to set resource regions in our documentation.
