Shooting the Rapids
Explore the performance factors of Java 8 streams in this comprehensive conference talk. Dive into the implementation details of stream processing, from Spliterators to Collectors and the Fork/Join framework for parallel streams. Analyze practical program measurements to develop guidelines for optimizing Java 8 stream performance and determining when parallel processing is beneficial. Learn about lambda expressions, method references, and terminal operations while examining real-world examples like processing GC logfiles. Compare old-school code with modern Java 8 streams, investigate data splitting techniques, and understand the impact of intermediate operations. Gain insights into amortizing setup costs, simulating server environments, and addressing resource bottlenecks in stream processing.
