Streaming Systems e-bog

Streaming data is a big deal in big data these days. As more and more businesses seek to tame the massive unbounded data sets that pervade our world, streaming systems have finally reached a level of maturity sufficient for mainstream adoption. With this practical guide, data engineers, data scientists, and developers will learn how to work with streaming data in a conceptual and platform-agnostic way.Expanded from Tyler Akidaus popular blog posts "e;Streaming 101"e; and "e;Streaming 102"e;, this book takes you from an introductory level to a nuanced understanding of the what, where, when, and how of processing real-time data streams. Youll also dive deep into watermarks and exactly-once processing with co-authors Slava Chernyak and Reuven Lax.Youll explore:How streaming and batch data processing patterns compareThe core principles and concepts behind robust out-of-order data processingHow watermarks track progress and completeness in infinite datasetsHow exactly-once data processing techniques ensure correctnessHow the concepts of streams and tables form the foundations of both batch and streaming data processingThe practical motivations behind a powerful persistent state mechanism, driven by a real-world exampleHow time-varying relations provide a link between stream processing and the world of SQL and relational algebra
