.NET Framework 4.5
Container for the parameters to the SetQueueAttributes operation. Sets the value of one or more queue attributes. When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15 minutes. Going forward, new attributes might be added. If you are writing code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

public class SetQueueAttributesRequest : AmazonSQSRequest

The SetQueueAttributesRequest type exposes the following members


Public Method SetQueueAttributesRequest() Empty constructor used to set properties independently even when a simple constructor is available
Public Method SetQueueAttributesRequest(string, Dictionary<String, String>)


Public Property Attributes System.Collections.Generic.Dictionary<System.String, System.String> Gets and sets the property Attributes.

A map of attributes to set.

The following lists the names, descriptions, and values of the special request parameters the SetQueueAttributes action uses:

  • DelaySeconds - The time in seconds that the delivery of all messages in the queue will be delayed. An integer from 0 to 900 (15 minutes). The default for this attribute is 0 (zero).
  • MaximumMessageSize - The limit of how many bytes a message can contain before Amazon SQS rejects it. An integer from 1024 bytes (1 KiB) up to 262144 bytes (256 KiB). The default for this attribute is 262144 (256 KiB).
  • MessageRetentionPeriod - The number of seconds Amazon SQS retains a message. Integer representing seconds, from 60 (1 minute) to 1209600 (14 days). The default for this attribute is 345600 (4 days).
  • Policy - The queue's policy. A valid AWS policy. For more information about policy structure, see Overview of AWS IAM Policies in the Amazon IAM User Guide.
  • ReceiveMessageWaitTimeSeconds - The time for which a ReceiveMessage call will wait for a message to arrive. An integer from 0 to 20 (seconds). The default for this attribute is 0.
  • VisibilityTimeout - The visibility timeout for the queue. An integer from 0 to 43200 (12 hours). The default for this attribute is 30. For more information about visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.
  • RedrivePolicy - The parameters for dead letter queue functionality of the source queue. For more information about RedrivePolicy and dead letter queues, see Using Amazon SQS Dead Letter Queues in the Amazon SQS Developer Guide.

Public Property QueueUrl System.String Gets and sets the property QueueUrl.

The URL of the Amazon SQS queue to take action on.


This example shows how to set queue attributes.

Set queue attributes example

var client = new AmazonSQSClient();

var attrs = new Dictionary<string, string>();

// Maximum message size of 128 KiB (1,024 bytes * 128 KiB = 131,072 bytes).
int maxMessage = 128 * 1024;

attrs.Add(QueueAttributeName.MaximumMessageSize, maxMessage.ToString());
// Dead-letter queue attributes.
  "{\"maxReceiveCount\":" +
  "\"5\"," +
  "\"deadLetterTargetArn\":" +

var request = new SetQueueAttributesRequest
  Attributes = attrs,
  QueueUrl = ""
