This year’s edition of J-Spring, organized by the NLJUG, went digital due to the COVID-19 pandemic. From the 23rd up to and including the 26th of June, every day two technical talks have been held. We attended this digital version of J-Spring and want to share some of our impressions. Enjoy!

1. Introduction

Due to the Corona virus, the NLJUG (the Java User Group in the Netherlands) decided to turn the J-Spring one day physical conference into a digital event. They spread the conference over multiple days in time blocks of 2 up to 2,5 hours. This was a good idea because attending a virtual conference for a whole day can be very exhausting. The event consisted of a fixed program of two talks at the end of each day. A nice ending of every day, we must say! In the following sections, we will share some of our impressions of the several talks.

2. Tuesday, the 23rd of June

2.1 Reacting to an Event Driven World

By Grace Jansen and Kate Stanley

This talk gave us an introduction of Reactive Programming, reactive patterns like Futures, Reactive Programming Libraries, Reactive Streams and of course the Reactive Manifesto. Besides that, the talk gave us an introduction to Apache Kafka. Very interesting if you want to have a quick overview of these two items. They provided a lot of interesting links to information about Reactive Programming, so watch out for the slides when being published.
