Amazon Simple Notification Service (Amazon SNS) now supports payload-based message filtering, expanding the feature set that already supported attribute-based message filtering. With this release, you can apply subscription filter policies to filter out messages based on their contents, unlocking a variety of workloads. You may use this new capability to filter events from 60+ AWS services that publish events to Amazon SNS, including Amazon S3, Amazon EC2, Amazon CloudFront, and Amazon CloudWatch. You may also use payload-based message filtering for your cross-account workloads, where subscribers may not be able to influence a given publisher to have its messages published with attributes to Amazon SNS.
