Questions tagged [spring-cloud-function]

Use this tag for questions related to the Spring Cloud Function project

Spring Cloud Function is a project in a Spring Cloud portfolio of projects with the following high-level goals:

  • Promote the implementation of business logic via java.util.function.(Supplier, Function, Consumer)
  • Provide necessary deployment and runtime abstractions to ensure the same code can run in multiple environments (e.g., a web endpoint, a stream processor, or a task).
  • Support a uniform programming model across serverless providers, as well as the ability to run standalone (locally or in a PaaS).
  • Enable Spring Boot features (auto-configuration, dependency injection, metrics) on serverless providers.
