JOTB19 - How (Not) to use reactive streams in Java 9+ by Jacek Kunicki
Did you try to implement one of the new java.util.concurrent.Flow.* interfaces yourself? Then you’re most probably doing it wrong.
The purpose of this talk is to show that implementing them yourself is far from trivial and to discuss the actual reasons why they have been included in the JDK.
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+. Plus we’re going to ponder the possible directions in which JDK’s Reactive Streams support may go in the future.
