The Core domain module includes the concept of a stream that is a composition of spring-cloud-stream modules in a linear pipeline from a source to a sink, optionally including processor modules in between. The domain also includes the concept of a task, which may be any process that does not run indefinitely, including Spring Batch jobs.

The Artifact Registry maintains the set of available modules, and their mappings to Maven coordinates.

The Module Deployer SPI provides the abstraction layer for deploying the modules of a given stream across a variety of runtime environments, including:

The Admin Starter provides the REST API and UI for implementations of the Admin SPI.

The Shell connects to the Admin’s REST API and supports a DSL that simplifies the process of defining a stream and managing its lifecycle.
