Explore the benefits of reactive programming beyond high-throughput scenarios in this conference talk from GOTO Berlin 2018. Discover how reactive systems address modern application challenges, including high user numbers and throughput. Learn about Project Reactor, debugging techniques, and the costs associated with blocking operations. Examine real-world examples from eBay Classifieds Group brands, including stream processing, back-pressure implementation, and client-side reactivity. Gain insights into suitable use cases for reactive programming and scenarios where it might not be the best fit. Delve into topics such as thread overhead, Fork Join Executor performance, and the implementation of reactive principles in various services and platforms.
