So I have a dynamodb table provisioned via cloudformation stack. Now I would like to update the dynamodb table to have mutilple GSI's.
The problem here is i dont have access to the CF Template that was used to initially create the dynamodb table.
Now, can i use a different CF Template to update the existing resource with additional config I am looking for referencing the ARN of the dynamodb table? If so, how do it achieve it?
