Amazon Simple Notification Service (SNS) now supports a higher default quota for subscription filter policies. With the increased quota, you can now have up to 10,000 subscription filter policies per account, and can apply up to 200 subscription filter policies per topic. By default, topic subscribers receive every message published to a topic. With subscription filter policies, subscribers can filter out unwanted messages, simplifying their architecture and optimizing the utilization of their resources.

Amazon SNS provides high-throughput, push-based, many-to-many messaging between distributed systems, microservices, and event-driven serverless applications. These applications include Amazon Simple Queue Service, Amazon Kinesis Data Firehose, Amazon Lambda, and HTTP/S endpoints.

The increased subscription filter policy quota is available in the Amazon Web Services China (Ningxia) Region, operated by NWCD, and the Amazon Web Services China (Beijing) Region, operated by Sinnet.

You may start using Amazon SNS message filtering and the new quota today, via the Amazon Web Services Management Console, Amazon CloudFormation, Amazon Developer Tools (SDK), Amazon SNS Command Line Interface (CLI), and the Amazon SNS Application Programming Interface (API).
