SQS / Client / create_queue
create_queue#
- SQS.Client.create_queue(**kwargs)#
Creates a new standard or FIFO queue. You can pass one or more attributes in the request. Keep the following in mind:
If you don’t specify the
FifoQueue
attribute, Amazon SQS creates a standard queue.
Note
You can’t change the queue type after you create it and you can’t convert an existing standard queue into a FIFO queue. You must either create a new FIFO queue for your application or delete your existing standard queue and recreate it as a FIFO queue. For more information, see Moving From a Standard Queue to a FIFO Queue in the Amazon SQS Developer Guide.
If you don’t provide a value for an attribute, the queue is created with the default value for the attribute.
If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.
To successfully create a new queue, you must provide a queue name that adheres to the limits related to queues and is unique within the scope of your queues.
Note
After you create a queue, you must wait at least one second after the queue is created to be able to use the queue.
To get the queue URL, use the
GetQueueUrl
action.GetQueueUrl
requires only theQueueName
parameter. be aware of existing queue names:If you provide the name of an existing queue along with the exact names and values of all the queue’s attributes,
CreateQueue
returns the queue URL for the existing queue.If the queue name, attribute names, or attribute values don’t match an existing queue,
CreateQueue
returns an error.
Note
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.

Request Syntax
response = client.create_queue( QueueName='string', Attributes={ 'string': 'string' }, tags={ 'string': 'string' } )
- Parameters:
QueueName (string) –
[REQUIRED]
The name of the new queue. The following limits apply to this name:
A queue name can have up to 80 characters.
Valid values: alphanumeric characters, hyphens (
-
), and underscores (_
).A FIFO queue name must end with the
.fifo
suffix.
Queue URLs and names are case-sensitive.
Attributes (dict) –
A map of attributes with their corresponding values.
The following lists the names, descriptions, and values of the special request parameters that the
CreateQueue
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 seconds (15 minutes). Default: 0.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) to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB).MessageRetentionPeriod
– The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 345,600 (4 days). 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 theMessageRetentionPeriod
attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if theMessageRetentionPeriod
is reduced below the age of existing messages.Policy
– The queue’s policy. A valid Amazon Web Services policy. For more information about policy structure, see Overview of Amazon Web Services IAM Policies in the IAM User Guide.ReceiveMessageWaitTimeSeconds
– The length of time, in seconds, for which aReceiveMessage
action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.VisibilityTimeout
– The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.
The following attributes apply only to dead-letter queues:
RedrivePolicy
– The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:deadLetterTargetArn
– The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value ofmaxReceiveCount
is exceeded.maxReceiveCount
– The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When theReceiveCount
for a message exceeds themaxReceiveCount
for a queue, Amazon SQS moves the message to the dead-letter-queue.
RedriveAllowPolicy
– The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:redrivePermission
– The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:allowAll
– (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.denyAll
– No source queues can specify this queue as the dead-letter queue.byQueue
– Only queues specified by thesourceQueueArns
parameter can specify this queue as the dead-letter queue.
sourceQueueArns
– The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when theredrivePermission
parameter is set tobyQueue
. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set theredrivePermission
parameter toallowAll
.
Note
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.
The following attributes apply only to server-side-encryption:
KmsMasterKeyId
– The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms. While the alias of the Amazon Web Services managed CMK for Amazon SQS is alwaysalias/aws/sqs
, the alias of a custom CMK can, for example, be ``alias/MyAlias ``. For more examples, see KeyId in the 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 KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 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?SqsManagedSseEnabled
– Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS).
The following attributes apply only to FIFO (first-in-first-out) queues:
FifoQueue
– Designates a queue as FIFO. Valid values aretrue
andfalse
. If you don’t specify theFifoQueue
attribute, Amazon SQS creates a standard queue. You can provide this attribute only during queue creation. You can’t change it for an existing queue. When you set this attribute, you must also provide theMessageGroupId
for your messages explicitly. For more information, see FIFO queue logic in the Amazon SQS Developer Guide.ContentBasedDeduplication
– Enables content-based deduplication. Valid values aretrue
andfalse
. For more information, see Exactly-once processing in the Amazon SQS Developer Guide. Note the following:Every message must have a unique
MessageDeduplicationId
.You may provide a
MessageDeduplicationId
explicitly.If you aren’t able to provide a
MessageDeduplicationId
and you enableContentBasedDeduplication
for your queue, Amazon SQS uses a SHA-256 hash to generate theMessageDeduplicationId
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 haveContentBasedDeduplication
set, the action fails with an error.If the queue has
ContentBasedDeduplication
set, yourMessageDeduplicationId
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 aMessageDeduplicationId
that is the same as the one generated for the firstMessageDeduplicationId
, the two messages are treated as duplicates and only one copy of the message is delivered.
The following attributes apply only to high throughput for FIFO queues:
DeduplicationScope
– Specifies whether message deduplication occurs at the message group or queue level. Valid values aremessageGroup
andqueue
.FifoThroughputLimit
– Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values areperQueue
andperMessageGroupId
. TheperMessageGroupId
value is allowed only when the value forDeduplicationScope
ismessageGroup
.
To enable high throughput for FIFO queues, do the following:
Set
DeduplicationScope
tomessageGroup
.Set
FifoThroughputLimit
toperMessageGroupId
.
If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.
For information on throughput quotas, see Quotas related to messages in the Amazon SQS Developer Guide.
(string) –
(string) –
tags (dict) –
Add cost allocation tags to the specified Amazon SQS queue. For an overview, see Tagging Your Amazon SQS Queues in the Amazon SQS Developer Guide.
When you use queue tags, keep the following guidelines in mind:
Adding more than 50 tags to a queue isn’t recommended.
Tags don’t have any semantic meaning. Amazon SQS interprets tags as character strings.
Tags are case-sensitive.
A new tag with a key identical to that of an existing tag overwrites the existing tag.
For a full list of tag restrictions, see Quotas related to queues in the Amazon SQS Developer Guide.
Note
To be able to tag a queue on creation, you must have the
sqs:CreateQueue
andsqs:TagQueue
permissions.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.
