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.

Deleting Resource Record Sets

To delete a resource record set, you must specify all the same values that you specified when you created it.

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. Route 53 validates the changes in the request and then either makes all or none of the changes in the change batch request. This ensures that DNS routing isn't adversely affected by partial changes to the resource record sets in a hosted zone.

For example, suppose a change batch request contains two changes: it deletes the CNAME resource record set for www.example.com and creates an alias resource record set for www.example.com. If validation for both records succeeds, Route 53 deletes the first resource record set and creates the second resource record set in a single operation. If validation for either the DELETE or the CREATE action fails, then the request is canceled, and the original CNAME record continues to exist.

If you try to delete the same resource record set more than once in a single change batch, 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 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 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:

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 Route 53 DNS Servers

When you submit a ChangeResourceRecordSets request, Route 53 propagates your changes to all of the Route 53 authoritative DNS servers managing the hosted zone. 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 Route 53 name servers managing the hosted zone within 60 seconds. For more information, see GetChange.

Limits on ChangeResourceRecordSets Requests

For information about the limits on a ChangeResourceRecordSets request, see Limits in the Amazon Route 53 Developer Guide.

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginChangeResourceRecordSets and EndChangeResourceRecordSets.

Namespace: Amazon.Route53
Assembly: AWSSDK.Route53.dll
Version: 3.x.y.z

Syntax

C#
public abstract Task<ChangeResourceRecordSetsResponse> ChangeResourceRecordSetsAsync(
         ChangeResourceRecordSetsRequest request,
         CancellationToken cancellationToken
)

Parameters

request
Type: Amazon.Route53.Model.ChangeResourceRecordSetsRequest

Container for the necessary parameters to execute the ChangeResourceRecordSets service method.

cancellationToken
Type: System.Threading.CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Return Value


The response from the ChangeResourceRecordSets service method, as returned by Route53.

Exceptions

ExceptionCondition
InvalidChangeBatchException This exception contains a list of messages that might contain one or more error messages. Each error message indicates one error in the change batch.
InvalidInputException The input is not valid.
NoSuchHealthCheckException No health check exists with the specified ID.
NoSuchHostedZoneException No hosted zone exists with the ID that you specified.
PriorRequestNotCompleteException If Amazon Route 53 can't process a request before the next request arrives, it will reject subsequent requests for the same hosted zone and return an HTTP 400 error (Bad request). If Route 53 returns this error repeatedly for the same request, we recommend that you wait, in intervals of increasing duration, before you try the request again.
