Quarkus why, how and what by Emmanuel Bernard

Microservices, rapid scalability & high density deployment platforms like Kubernetes require apps with low memory usage and fast boot time.

Java had been the outsider due to its focus on throughput at the expense of CPU & RAM. No more. Enter Quarkus, a microservices Java stack bringing your favorite libs (Hibernate, vert.x, Camel, RESTEasy ...) to GraalVM and HotSpot with low memory usage and fast boot time.

Enough to swim in containers like fish in water. Data is usually the hardest part, lets demonstrate Quarkus with persistence and Hibernate ORM.

Come explore live reload, opinionated persistence with Hibernate Panache, testing, GraalVM native compilation and more.

Since Quarkus is better lived than talked, expect a heavy demo session.

So happy when I saw 14:50, reversed stack...so I don't have to literally go digging trough trash

This is awesome, i can't wait to try this on my next rest project

Excellent job! But I have a problem with @Valid annotation doesn’t works inside a rest api. For example if I use @NotNull for a field and I try a create with null field, there is no exception and document was created. Also for @Size or @NotBlank ☹️

I see Dependency injection dont work in Lambads, any updates on that

[jubinkuriakose]

I see that demo uses vertx how are the both related?
