Details

Helidon is an open-source, cloud-native set of Java libraries from Oracle for building microservices. It provides two distinct paths for development. Helidon SE is a lightweight, “reactive” toolkit that uses a functional, non-blocking approach (built on Netty) for maximum performance and a small footprint. Helidon MP is a full implementation of the Eclipse MicroProfile specification, providing a more declarative, annotation-driven programming model (similar to Spring Boot or Micronaut) for enterprise Java developers.
