“The native executables start up
almost 100X faster and
consume up to 5X less memory
compared to running on a JVM”

14. Quarkus Build Flow
Build item
Build item are communication
mechanism between build steps
1. Initial state build items
2. Intermediate state build item
3. Terminal state build item

15. Quarkus Build Flow
Build step
Build steps are methods annotated with @BuildStep annotation that performs a step in
the build process

Key aspects of Quarkus extensions philosophy:
● Modularity: Extensions are designed to be self-contained units
of functionality
● Simplicity: Quarkus extensions aim to simplify the integration
of third-party libraries and technologies
● Configuration: Extensions often provide well-defined
configuration options that align with Quarkus' overall
configuration model
● Optimization: Extensions focused on optimization offer a
diverse range of benefits that elevate performance through the
utilization of recording bytecode

18. Extension Concept in Quarkus

jandex
● Find classes, methods, fields having
same annotation
● Find classes implementing an
interface
● Eliminates need for runtime classpath
scanning
● Closed world easy to build-time
optimise

21. Extension Concept in Quarkus
● Quarkus is part of the GraalVM test suite
● Mandrel is downstream distribution of GraalVM
Mandrel: A specialized distribution of GraalVM for Quarkus
● Red Hat contributes to GraalVM
