Amazon Simple Notification Service (Amazon SNS) now supports message group IDs in standard topics, enabling fair queue functionality for all subscribed Amazon SQS standard queues. This feature allows you to mitigate noisy neighbor impact in all multi-tenant standard queues subscribed to a SNS standard topic by ensuring that high-volume or slow-processing messages from one tenant don’t delay messages from other tenants.
When you include a message group ID in messages sent to your Amazon SNS standard topic, the topic automatically forwards these IDs to all subscribed Amazon SQS standard queues, activating fair queue behavior across those queues. This capability is particularly valuable for SaaS applications that use Amazon SNS to distribute messages to multiple processing queues, event-driven architectures serving multiple customers, and microservices that need to maintain quality of service across different request types.
This feature is now available in all AWS commercial and AWS GovCloud (US) Regions. To learn more about using message group IDs with Amazon SNS, see the Amazon SNS Developer Guide. For more information about Amazon SQS fair queues, read our blog post.
