New Concurrency Models on the JVM - Fibres, Verticles, Agents and Actors

Explore new concurrency models on the JVM in this comprehensive conference talk. Delve into the limitations of traditional thread-based concurrency in Java and discover alternative approaches for fine-grained concurrency below the thread level. Learn about Quasar Fibres, Clojure Agents, vert.x Verticles, and Akka Actors, examining their advantages and disadvantages. Gain insights into modern processor architectures, resource management, and the challenges of shared mutable state. Follow along as the speaker demonstrates examples of Fibres, Channels, Go Block, Event Loop, Verticle deployment, and Actor creation. Understand the evolution of concurrency models and their impact on Java development, from the original concept of threads as "lightweight processes" to the current paradigm shift towards more efficient and scalable solutions.
