As previously answered via Slack, you can find a nice example on how to integrate the AWS SDK for Go with Alternator under alternator-load-balancing/try.go at master · scylladb/alternator-load-balancing · GitHub
The example in question makes use of our Alternator Load Balancing library to ensure requests are load balanced automatically on the client side. Should you not be using it, just remove the references to the library and proceed as usual.
Cheers!
