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 software.amazon.awscdk.services.sqs.*;
Here's how to add a basic queue to your application:
new Queue(this, "Queue");
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 // Use managed key Queue.Builder.create(this, "Queue") .encryption(QueueEncryption.KMS_MANAGED) .build(); // Use custom key Key myKey = new Key(this, "Key"); Queue.Builder.create(this, "Queue") .encryption(QueueEncryption.KMS) .encryptionMasterKey(myKey) .build();
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.
