An airhacks.fm conversation with Dimitris Andreadis (@dandreadis) about:

eclipsecon, Quarkus 1.0 and 1.0.1 releases,

Quarkus is 8 months young, more extensions, more reactive functionality,

97 external committers and 93 RedHat committers, opinionated view vs. expansion and experimentation, Quarkus long term support, the three levels of extensions,

quarkus extensions registry, the idea of composite extensions, emulating the composite extensions with a no-op extension,

emulating the "all" injection setting in beans.xml, Quarkus uses Jandex for annotation searching,

there is no greenfield development, many new developers are coming from SpringBoot, Kubernetes Native Spring apps on Quarkus by Georgios Andrianakis,

Vodafone Greece replaces SpringBoot with Quarkus,

the business case of SpringBoot to Quarkus migration was RAM consumption, boot time improvement with Quarkus,

J9 JVM improves startup time, external dependencies are bad for startup time, Quarkus power is Java optimization,

Quarkus optimises the standard Java HotSpot application, GraalVM optimizes it even further, Quarkus performs Hibernate optimizations

at build time and not deployment time, Quarkus does not include SpringBoot library, Quarkus provides a Spring API compatibility layer which is converted at build time,

Spring is emulated on Quarkus, the Spring compatibility layer was implemented in a month, Quarkus is built on 20 years old wisdom like Hibernate or Transaction Manager etc,

in the Vodafone case, Quarkus reduced 60% of RAM, with memory savings come cost savings, the fast boot time is important for scaling in the clouds,

Quarkus is comparable to React -- comes with free memory improvements without migrations, Quarkus ships with Vert.x,

the Quarkus Vault extension, the SpringBoot compatibility layer is conceptually similar to Linux Wine compatibility layer,

Quarkus would like to stay away from EJB, EJBs are faster than CDI on regular application servers on Quarkus the performance could be comparable with RequestScoped, Quarkus ships with built-in CORS filter,

Keycloak supports oauth flows with a Gateway (Gatekeeper), Quarkus comes with native JWT Microprofile support,

two Quarkus books are in the pipeline, keeping the conventions and usability of Quarkus could become a challenge,

Quarkus will also come with tight OpenShift integration, the Engineering Director of the Extended Quarkus Team
