Are there functions or features available in Quarkus that are not in Spring?

Quarkus and Spring are popular Java frameworks, but Quarkus is focused on creating cloud-native and containerized applications with an emphasis on fast startup and small size.

Features of Quarkus that are absent or implemented differently in Spring:

• Native compilation with GraalVM: Quarkus supports creating native executables, which significantly speeds up startup and reduces memory consumption.
• Built-in live reload support: Quarkus allows quick code changes to be reflected without restarting the application.
• Optimized for Kubernetes and cloud environments: built-in support for configurations and integrations for cloud platforms.
• Smaller size and faster loading: Quarkus is specifically optimized for microservices and serverless.

Spring is also evolving in these directions, but Quarkus was originally designed with these requirements in mind.

Example of using Quarkus with native compilation:

./mvnw package -Pnative

This will create a native executable, which is not available out of the box in Spring.
