HAQM Simple Notification Service (SNS) message filtering now supports attribute key matching. This feature lets you create an HAQM SNS subscription filter policy that matches incoming messages which contain an attribute key, regardless of the attribute value associated with this key. This feature lets you offload additional message filtering logic to HAQM SNS.
HAQM SNS message filtering lets you simplify your pub/sub messaging architecture by offloading message filtering logic from your subscriber systems as well as message routing logic from your publisher systems. HAQM SNS message filtering offers a variety of matching operators:
- Attribute string value matching (whitelisting, blacklisting, prefix matching)
- Attribute numeric value matching (whitelisting, blacklisting, range matching)
- Attribute key matching
HAQM SNS is a fully managed pub/sub messaging service. You can use HAQM SNS topics to decouple message publishers and subscribers, and simultaneously distribute messages to multiple endpoints, such as HAQM SQS queues, AWS Lambda functions, HTTP endpoints, email addresses, and mobile devices (SMS text messages, mobile push notifications).
For more information, see Message Filtering and Subscription Filter Policies in the HAQM SNS Developer Guide.
