AWS AppSync WebSockets-based subscriptions for real-time updates support nested filtering
AWS AppSync is a fully managed service that enables developers to build digital experiences based on real-time data. With AppSync, you can configure data sources to push and publish real-time data updates to subscribed clients. AppSync handles connection management, scalability, fan-out and broadcasting, allowing you to focus on your application business needs instead of managing complex infrastructure. With AppSync, developers can easily specify filtering roles for their subscriptions to target specific connected clients based on the published data.

AppSync handles connection management, scalability, fan-out and broadcasting, allowing you to focus on your application business needs instead of managing complex infrastructure. With AppSync, developers can easily specify filtering roles for their subscriptions to target specific connected clients based on the published data.
AppSync now supports nested filters in filtering rules, allowing developers to target specific sub-items within the published data. This new capability gives developers additional control over how data should be published out to connected clients. Because developers do not have to make changes to their nested data, they can start using the functionality of AppSync’s pub/sub engine right away, and can implement real-time experiences based on existing data models.
This feature is available in all AWS Regions where AppSync is available. For more details, refer to our blog post and the AppSync documentation.
