Ops tooling has so far been the domain of shell scripts, interpreted languages like Python or statically compile languages like Go. But with the advent of GraalVM this situation has changed significantly. But behold: it is now possible to apply the power of the Java language and its ecosystem to your DevOps tooling problems and yet get optimal performance and efficiency by using GraalVM native images. In this session we will show that versatile 12-factor CLIs and powerful Kubernetes operators can be implemented in Java super easy in no time.

Not too long ago, a reactive variant of the JDBC API was released, known as Reactive Relational Database Connectivity (R2DBC). While R2DBC started as an experiment to enable integration of SQL databases into systems that use reactive programming models, it now specifies a robust specification that can be implemented to manage data in a fully reactive and completely non-blocking fashion. In this session, we’ll briefly go over the fundamentals that make R2DBC so powerful. We'll keep light on the slides so that we can jump directly into application code to get a firsthand look at the recently released R2DBC driver from MariaDB. From there, we'll examine how you can take advantage of crucial concepts, like event-driven behavior and backpressure, that enable fully reactive, non-blocking interactions with a relational database. Join Rob Hedgpeth, MariaDB's developer evangelist, as he:

• Introduces MariaDB Connector/R2DBC

• Examines the advantages of fully reactive, non-blocking development with MariaDB

• Provides a firsthand look at what it’s like to use the new connector with some live coding
