setQueueAttributes

Sets the value of one or more queue attributes, like a policy. When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the MessageRetentionPeriod is reduced below the age of existing messages.

• In the future, new attributes might be added. If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

• Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide.

• To remove the ability to change queue permissions, you must deny permission to the AddPermission, RemovePermission, and SetQueueAttributes actions in your IAM policy.
