In this presentation, Akka Team Lead and author Roland Kuhn presents the freshly released final specification for Reactive Streams on the JVM. This work was done in collaboration with engineers representing Netflix, Red Hat, Pivotal, Oracle, Typesafe and others to define a standard for passing streams of data between threads in an asynchronous and non-blocking fashion. This is a common need in Reactive systems, where handling streams of "live" data whose volume is not predetermined.
The most prominent issue facing the industry today is that resource consumption needs to be controlled such that a fast data source does not overwhelm the stream destination. Asynchrony is needed in order to enable the parallel use of computing resources, on collaborating network hosts or multiple CPU cores within a single machine.
Here we'll review the mechanisms employed by Reactive Streams, discuss the applicability of this technology to a variety of problems encountered in day to day work on the JVM, and give an overview of the tooling ecosystem that is emerging around this young standard.
