Spring Cloud Stream is a framework for building highly scalable event-driven microservices connected with shared messaging systems.
The framework provides a flexible programming model built on already established and familiar Spring idioms and best practices, including support for persistent pub/sub semantics, consumer groups, and stateful partitions.
Spring Cloud Stream supports a variety of binder implementations and the following table includes the link to the GitHub projects.
The core building blocks of Spring Cloud Stream are:
Destination Binders: Components responsible to provide integration with the external messaging systems.
Destination Bindings: Bridge between the external messaging systems and application code (producer/consumer) provided by the end user.
Message: The canonical data structure used by producers and consumers to communicate with Destination Binders (and thus other applications via external messaging systems).
Artifacts for various modules of spring-cloud-stream available in Maven Central repository under spring-cloud-stream-*.
