--
-- Creates, changes, or deletes a resource record set, which contains authoritative DNS information for a specified domain name or subdomain name. For example, you can use @ChangeResourceRecordSets@ to create a resource record set that routes traffic for test.example.com to a web server that has an IP address of 192.0.2.44.
--
--
-- __Change Batches and Transactional Changes__
--
-- The request body must include a document with a @ChangeResourceRecordSetsRequest@ element. The request body contains a list of change items, known as a change batch. Change batches are considered transactional changes. When using the Amazon Route 53 API to change resource record sets, Amazon Route 53 either makes all or none of the changes in a change batch request. This ensures that Amazon Route 53 never partially implements the intended changes to the resource record sets in a hosted zone.
--
-- For example, a change batch request that deletes the @CNAME@ record for www.example.com and creates an alias resource record set for www.example.com. Amazon Route 53 deletes the first resource record set and creates the second resource record set in a single operation. If either the @DELETE@ or the @CREATE@ action fails, then both changes (plus any other changes in the batch) fail, and the original @CNAME@ record continues to exist.
--
-- /Important:/ Due to the nature of transactional changes, you can't delete the same resource record set more than once in a single change batch. If you attempt to delete the same change batch more than once, Amazon Route 53 returns an @InvalidChangeBatch@ error.
--
-- __Traffic Flow__
--
-- To create resource record sets for complex routing configurations, use either the traffic flow visual editor in the Amazon Route 53 console or the API actions for traffic policies and traffic policy instances. Save the configuration as a traffic policy, then associate the traffic policy with one or more domain names (such as example.com) or subdomain names (such as www.example.com), in the same hosted zone or in multiple hosted zones. You can roll back the updates if the new configuration isn't performing as expected. For more information, see <http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/traffic-flow.html Using Traffic Flow to Route DNS Traffic> in the /Amazon Route 53 Developer Guide/ .
--
-- __Create, Delete, and Upsert__
--
-- Use @ChangeResourceRecordsSetsRequest@ to perform the following actions:
--
--     * @CREATE@ : Creates a resource record set that has the specified values.
--
--     * @DELETE@ : Deletes an existing resource record set that has the specified values.
--
--     * @UPSERT@ : If a resource record set does not already exist, AWS creates it. If a resource set does exist, Amazon Route 53 updates it with the values in the request.
--
--
--
-- __Syntaxes for Creating, Updating, and Deleting Resource Record Sets__
--
-- The syntax for a request depends on the type of resource record set that you want to create, delete, or update, such as weighted, alias, or failover. The XML elements in your request must appear in the order listed in the syntax.
--
-- For an example for each type of resource record set, see "Examples."
--
-- Don't refer to the syntax in the "Parameter Syntax" section, which includes all of the elements for every kind of resource record set that you can create, delete, or update by using @ChangeResourceRecordSets@ .
--
-- __Change Propagation to Amazon Route 53 DNS Servers__
--
-- When you submit a @ChangeResourceRecordSets@ request, Amazon Route 53 propagates your changes to all of the Amazon Route 53 authoritative DNS servers. While your changes are propagating, @GetChange@ returns a status of @PENDING@ . When propagation is complete, @GetChange@ returns a status of @INSYNC@ . Changes generally propagate to all Amazon Route 53 name servers within 60 seconds. For more information, see 'GetChange' .
--
-- __Limits on ChangeResourceRecordSets Requests__
--
-- For information about the limits on a @ChangeResourceRecordSets@ request, see <http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/DNSLimitations.html Limits> in the /Amazon Route 53 Developer Guide/ .
