Helidon Nima - Loom based microservices framework

Dmitry Kornilov (Oracle)

For quite a long time we were forced to make a choice - performance vs. simplicity. Either use a complicated and performant reactive code, or use simple, yet limited blocking approach.Thanks to project Loom in JDK, the paradigm can shift once more even for applications that require high concurrency. I will introduce Helidon Nima - new microservices framework which is built on top of a server designed for Loom with fully synchronous routing that can block as needed, yet still provide high performance under heavy concurrent load.

MicroProfile Long Running Actions in Helidon

Daniel Kec (Oracle)

New MicroProfile Long Running Actions specification brings easy to use means to use SAGA pattern in your project. Lets explore this new specification with practical live coding demo. We will setup simple Helidon app with LRA client and connect it to Narayana LRA coordinator.

Event sourcing database with MicroProfile Reactive Messaging

Daniel Kec (Oracle)

Let's take a look how CDC(Change Data Capture) can be done with triggers and message queuing service built directly in the Oracle Database and how easy it is to integrate it with MicroProfile Reactive Messaging. We will create Always free instance of Oracle Database in Oracle Cloud(OCI), setup simple data capture with triggers and build in queuing and consume the data with MicroProfile Reactive Messaging AQ connector in Helidon.

Invited Talk: Developing cloud-native microservices using project Helidon

Dmitry Kornilov (Oracle)
Tomas Langer (Oracle)

Come learn about developing microservices using Helidon. Helidon is an open source project led by Oracle. It's a collection of Java libraries for building microservices. In this session we will talk about two programming models supported by Helidon: lightweight, functional model using JDK as runtime for those wanting less “magic” and Microprofile for those wanting inversion of control and familiar Java EE APIs. We will show how to quickly create your first Helidon application which uses both programming models.
