Synopsis

Calls the Amazon Simple Queue Service SetQueueAttributes API operation.

Syntax

Set-SQSQueueAttribute
-QueueUrl <String>
-Attribute <Hashtable>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

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 Amazon SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15 minutes. 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.

Parameters

-Attribute <Hashtable>
A map of attributes to set.The following lists the names, descriptions, and values of the special request parameters that the SetQueueAttributes action uses:
  • DelaySeconds - The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 (15 minutes). The default is 0 (zero).
  • MaximumMessageSize - The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) up to 262,144 bytes (256 KiB). The default is 262,144 (256 KiB).
  • MessageRetentionPeriod - The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer representing seconds, from 60 (1 minute) to 1,209,600 (14 days). The default is 345,600 (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 length of time, in seconds, for which a ReceiveMessage action waits for a message to arrive. Valid values: an integer from 0 to 20 (seconds). The default is 0.
  • RedrivePolicy - The string that includes the parameters for the dead-letter queue functionality of the source queue. For more information about the redrive policy and dead-letter queues, see Using Amazon SQS Dead-Letter Queues in the Amazon Simple Queue Service Developer Guide.
    • deadLetterTargetArn - The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of maxReceiveCount is exceeded.
    • maxReceiveCount - The number of times a message is delivered to the source queue before being moved to the dead-letter queue.
    The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.
  • VisibilityTimeout - The visibility timeout for the queue. Valid values: an integer from 0 to 43,200 (12 hours). The default is 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.
The following attributes apply only to server-side-encryption:
  • KmsMasterKeyId - The ID of an AWS-managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms. While the alias of the AWS-managed CMK for Amazon SQS is always alias/aws/sqs, the alias of a custom CMK can, for example, be alias/MyAlias. For more examples, see KeyId in the AWS Key Management Service API Reference.
  • KmsDataKeyReusePeriodSeconds - The length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling AWS KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). The default is 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see How Does the Data Key Reuse Period Work?.
The following attribute applies only to FIFO (first-in-first-out) queues:
  • ContentBasedDeduplication - Enables content-based deduplication. For more information, see Exactly-Once Processing in the Amazon Simple Queue Service Developer Guide.
    • Every message must have a unique MessageDeduplicationId,
      • You may provide a MessageDeduplicationId explicitly.
      • If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).
      • If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.
      • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.
    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.
    • If you send one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered.
Any other valid special request parameters (such as the following) are ignored:
  • ApproximateNumberOfMessages
  • ApproximateNumberOfMessagesDelayed
  • ApproximateNumberOfMessagesNotVisible
  • CreatedTimestamp
  • LastModifiedTimestamp
  • QueueArn
Required?False
Position?2
Accept pipeline input?False
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-PassThru <SwitchParameter>
Returns the value passed to the QueueUrl parameter. By default, this cmdlet does not generate any output.
Required?False
Position?Named
Accept pipeline input?False
-QueueUrl <String>
The URL of the Amazon SQS queue whose attributes are set.Queue URLs are case-sensitive.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String object to this cmdlet for the QueueUrl parameter.

Outputs

None or System.String
When you use the PassThru parameter, this cmdlet outputs the value supplied to the QueueUrl parameter. Otherwise, this cmdlet does not return any output. The service response (type Amazon.SQS.Model.SetQueueAttributesResponse) can be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

# create the queue and topic to be associated
PS C:\>$qurl = New-SQSQueue -QueueName "myQueue"
PS C:\>$topicarn = New-SNSTopic -Name "myTopic"

# get the queue ARN to inject into the policy; it will be returned
# in the output's QueueARN member but we need to put it into a variable
# so text expansion in the policy string takes effect
PS C:\>$qarn = (Get-SQSQueueAttribute -QueueUrl $qurl -AttributeName "QueueArn").QueueARN

# construct the policy and inject arns
PS C:\>$policy = @"
{
"Version": "2008-10-17",
"Id": "$qarn/SQSPOLICY",
"Statement": [
{
"Sid": "1",
"Effect": "Allow",
"Principal": "*",
"Action": "SQS:SendMessage",
"Resource": "$qarn",
"Condition": {
"ArnEquals": {
"aws:SourceArn": "$topicarn"
}
}
}
]
}
"@

# set the policy
PS C:\>Set-SQSQueueAttribute -QueueUrl $qurl -Attribute @{ Policy=$policy }
This example shows how to set a policy subscribing a queue to an SNS topic. When a message is published to the topic, a message is sent to the subscribed queue.

Example 2

PS C:\>Set-SQSQueueAttribute -Attribute @{"DelaySeconds" = "10"; "MaximumMessageSize" = "131072"} -QueueUrl https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue
This example sets the specified attributes for the specified queue.
