Amazon Simple Queue Service Construct Library

Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message oriented middleware, and empowers developers to focus on differentiating work. Using SQS, you can send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available.

Installation

Import to your project:

import sqs "github.com/aws/aws-cdk-go/awscdk"

Basic usage

Here's how to add a basic queue to your application:

sqs.NewQueue(this, jsii.String("Queue"))

Encryption

By default queues are encrypted using SSE-SQS. If you want to change the encryption mode, set the encryption property. The following encryption modes are supported:

  • KMS key that SQS manages for you
  • KMS key that you can managed yourself
  • Server-side encryption managed by SQS (SSE-SQS)
  • Unencrypted

To learn more about SSE-SQS on Amazon SQS, please visit the Amazon SQS documentation.

// Use managed key
// Use managed key
sqs.NewQueue(this, jsii.String("Queue"), &QueueProps{
	Encryption: sqs.QueueEncryption_KMS_MANAGED,
})

// Use custom key
myKey := kms.NewKey(this, jsii.String("Key"))

sqs.NewQueue(this, jsii.String("Queue"), &QueueProps{
	Encryption: sqs.QueueEncryption_KMS,
	EncryptionMasterKey: myKey,
})

// Use SQS managed server side encryption (SSE-SQS)
// Use SQS managed server side encryption (SSE-SQS)
sqs.NewQueue(this, jsii.String("Queue"), &QueueProps{
	Encryption: sqs.QueueEncryption_SQS_MANAGED,
})

// Unencrypted queue
// Unencrypted queue
sqs.NewQueue(this, jsii.String("Queue"), &QueueProps{
	Encryption: sqs.QueueEncryption_UNENCRYPTED,
})

Encryption in transit

If you want to enforce encryption of data in transit, set the enforceSSL property to true. A resource policy statement that allows only encrypted connections over HTTPS (TLS) will be added to the queue.

sqs.NewQueue(this, jsii.String("Queue"), &QueueProps{
	EnforceSSL: jsii.Boolean(true),
})

First-In-First-Out (FIFO) queues

FIFO queues give guarantees on the order in which messages are dequeued, and have additional features in order to help guarantee exactly-once processing. For more information, see the SQS manual. Note that FIFO queues are not available in all AWS regions.

A queue can be made a FIFO queue by either setting fifo: true, giving it a name which ends in ".fifo", or by enabling a FIFO specific feature such as: content-based deduplication, deduplication scope or fifo throughput limit.

Dead letter source queues permission

You can configure the permission settings for queues that can designate the created queue as their dead-letter queue using the redriveAllowPolicy attribute.

By default, all queues within the same account and region are permitted as source queues.

var sourceQueue iQueue


// Only the sourceQueue can specify this queue as the dead-letter queue.
queue1 := sqs.NewQueue(this, jsii.String("Queue2"), &QueueProps{
	RedriveAllowPolicy: &RedriveAllowPolicy{
		SourceQueues: []*iQueue{
			sourceQueue,
		},
	},
})

// No source queues can specify this queue as the dead-letter queue.
queue2 := sqs.NewQueue(this, jsii.String("Queue"), &QueueProps{
	RedriveAllowPolicy: &RedriveAllowPolicy{
		RedrivePermission: sqs.RedrivePermission_DENY_ALL,
	},
})

Functions

func CfnQueueInlinePolicy_CFN_RESOURCE_TYPE_NAME added in v2.91.0 

func CfnQueueInlinePolicy_CFN_RESOURCE_TYPE_NAME() *string

func CfnQueueInlinePolicy_IsCfnElement added in v2.91.0 

func CfnQueueInlinePolicy_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnQueueInlinePolicy_IsCfnResource added in v2.91.0 

func CfnQueueInlinePolicy_IsCfnResource(x interface{}) *bool

Check whether the given object is a CfnResource.

func CfnQueueInlinePolicy_IsConstruct added in v2.91.0 

func CfnQueueInlinePolicy_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func CfnQueuePolicy_CFN_RESOURCE_TYPE_NAME 

func CfnQueuePolicy_CFN_RESOURCE_TYPE_NAME() *string

func CfnQueuePolicy_IsCfnElement

The `AWS::SQS::Queue` resource creates an Amazon SQS standard or FIFO queue.

Keep the following caveats in mind:

- If you don't specify the `FifoQueue` property, Amazon SQS creates a standard queue.

> 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](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues-moving.html) in the *Amazon SQS Developer Guide* . - If you don't provide a value for a property, the queue is created with the default value for the property. - 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](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/limits-queues.html) and is unique within the scope of your queues.

For more information about creating FIFO (first-in-first-out) queues, see [Creating an Amazon SQS queue ( AWS CloudFormation )](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/screate-queue-cloudformation.html) in the *Amazon SQS Developer Guide* .

The policy for an SQS Queue.

Policies define the operations that are allowed on this resource.

You almost never need to define this construct directly.

All AWS resources that support resource policies have a method called `addToResourcePolicy()`, which will automatically create a new resource policy if one doesn't exist yet, otherwise it will add to the existing policy.

Prefer to use `addToResourcePolicy()` instead.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

var queue queue

queuePolicy := awscdk.Aws_sqs.NewQueuePolicy(this, jsii.String("MyQueuePolicy"), &QueuePolicyProps{
	Queues: []iQueue{
