Explore parallel streams in Java 8 to maximize CPU core utilization in this 46-minute conference talk by Lukasz Pater, a developer and programmer at CERN. Learn how the Streams API simplifies parallelism compared to traditional threading approaches. Discover the inner workings of the parallelStream method, understand key rules and best practices for effective implementation, and gain insights into avoiding common traps and performance issues. Delve into topics such as Spliterators, the Fork/Join Framework, and the decomposition of different stream sources. Compare parallel streams with earlier multithreading techniques and examine important considerations like decomposability and auto(un)boxing. Master methods like findAny(), unordered(), sequential(), and parallel() to optimize your parallel stream operations.
