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.
Import to your project:
import aws_cdk.aws_sqs as sqs
Here’s how to add a basic queue to your application:
If you want to encrypt the queue contents, set the
encryption property. You can have
the messages encrypted with a key that SQS manages for you, or a key that you
can manage yourself.
# Use managed key sqs.Queue(self, "Queue", encryption=sqs.QueueEncryption.KMS_MANAGED ) # Use custom key my_key = kms.Key(self, "Key") sqs.Queue(self, "Queue", encryption=sqs.QueueEncryption.KMS, encryption_master_key=my_key )
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
".fifo", or by enabling a FIFO specific feature such as: content-based deduplication,
deduplication scope or fifo throughput limit.
