// Updates the resource record sets in a specified hosted zone that were created
// based on the settings in a specified traffic policy version. When you update a
// traffic policy instance, Amazon Route 53 continues to respond to DNS queries for
// the root resource record set name (such as example.com) while it replaces one
// group of resource record sets with another. Route 53 performs the following
// operations:
//
// * Route 53 creates a new group of resource record sets based on the
// specified traffic policy. This is true regardless of how significant the
// differences are between the existing resource record sets and the new resource
// record sets.
//
// * When all of the new resource record sets have been created,
// Route 53 starts to respond to DNS queries for the root resource record set name
// (such as example.com) by using the new resource record sets.
//
// * Route 53 deletes
// the old group of resource record sets that are associated with the root resource
// record set name.
