Use this action to create or change your authoritative DNS information. To use this action, send a POST request to the 2013-04-01/hostedzone/hosted Zone ID/rrset resource. The request body must include an XML document with a ChangeResourceRecordSetsRequest element.

Changes are a list of change items and are considered transactional. For more information on transactional changes, also known as change batches, see Creating, Changing, and Deleting Resource Record Sets Using the Route 53 API in the Amazon Route 53 Developer Guide .

IMPORTANT:Due to the nature of transactional changes, you cannot 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, Route 53 returns an InvalidChangeBatch error.

In response to a ChangeResourceRecordSets request, your DNS data is changed on all Route 53 DNS servers. Initially, the status of a change is PENDING . This means the change has not yet propagated to all the authoritative Route 53 DNS servers. When the change is propagated to all hosts, the change returns a status of INSYNC .

Note the following limitations on a ChangeResourceRecordSets request:

- A request cannot contain more than 100 Change elements.

- A request cannot contain more than 1000 ResourceRecord elements.

The sum of the number of characters (including spaces) in all Value elements in a request cannot exceed 32,000 characters.
