I Heart Logs 
Event Data, Stream Processing, and Data Integration

Why a book about logs? Thats easy: the humble log is an abstraction that lies at the heart of many systems, from No SQL databases to cryptocurrencies. Even though most engineers dont think much about them, this short book shows you why logs are worthy of your attention.Based on his popular blog posts, Linked In principal engineer Jay Kreps shows you how logs work in distributed systems, and then delivers practical applications of these concepts in a variety of common usesdata integration, enterprise architecture, real-time stream processing, data system design, and abstract computing models.Go ahead and take the plunge with logs; youre going love them.Learn how logs are used for programmatic access in databases and distributed systems Discover solutions to the huge data integration problem when more data of more varieties meet more systems Understand why logs are at the heart of real-time stream processing Learn the role of a log in the internals of online data systems Explore how Jay Kreps applies these ideas to his own work on data infrastructure systems at Linked In
