Comparing a REST H2 Spring versus Quarkus application on Raspberry Pi

Goal of this comparison

In my previous post “A Spring REST and H2 database application on the Raspberry Pi” an example was described to store sensors and measurements in a H2-database through REST API’s with a Spring application on the Raspberry Pi. This application takes some time to start on a Raspberry Pi, and Adam Bien who makes the airhacks.fm podcast asked me if I could compare this to a similar Quarkus application.

Java on Raspberry Pi

The “Pi” in the name of the Raspberry Pi refers to Python, but as a Java developer I love to know and experiment with the various Java frameworks I also use at work. Spring is the main one, and I wanted to develop a proof-of-concept application which provides REST API’s to store and retrieve sensor data with a database back-end on the Raspberry Pi.

Reactive Spring Flux data from a Pi

Trisha Gee (Coder, blogger, speaker, Developer Advocate at JetBrains, @trisha_gee), which I interviewed for “Chapter 4: Choosing an IDE”, and Josh Long (Spring Developer Advocate at Pivotal, @starbuxman) worked together on a blog series in which they showed the power of reactive data produced by a Spring application. Instead of repeating a REST call each time you want to get data from the server, you do one call which returns a continuous stream in which new data is pushed based on an interval.
