I'm a passionate software engineer living in the JVM land - mainly, but not limited to. I also tend to play with electronics and hardware. When sharing my knowlegde, I always keep in mind that a working example is worth a thousand words.
Reactive Streams is a standard for asynchronous data processing in a streaming fashion with non-blocking backpressure. Starting from Java 9, they have become a part of the JDK in the form of the java.util.concurrent.Flow interfaces.
Having the interfaces at hand may tempt you to write your own implementations. Surprising as it may seem, that’s not what they are in the JDK for.
In this session we’re going to go through the basic concepts of reactive stream processing and see how (not) to use the APIs included in JDK 9+.
