Amazon AppFlow supports importing custom dimensions and metrics from Google Analytics to Amazon S3

By GIXnews

Amazon AppFlow, a fully managed integration service that enables customers to securely transfer data between AWS services and cloud applications, now allows you to import custom dimensions and metrics from Google Analytics into Amazon S3. You can specify the custom dimensions and metrics that you want to import while mapping source fields to the destination fields during flow set up and AppFlow will transfer records, including these dimensions and metrics, during flow execution.
