Clojure High Performance Programming

More Information
  • Learn techniques for achieving numerical performance in Clojure
  • Use Java features in Clojure code for performance
  • Avoid reflection and boxing with type hints
  • Analyze latency using the Criterium library
  • Understand Clojure's concurrency and state-management primitives in depth
  • Explore how to design Clojure applications for better performance

Clojure is a young, dynamic, functional programming language that runs on the Java Virtual Machine. It is built with performance, pragmatism, and simplicity in mind. Like most general purpose languages, Clojure’s features have different performance characteristics that one should know in order to write high performance code.

Clojure High Performance Programming is a practical, to-the-point guide that shows you how to evaluate the performance implications of different Clojure abstractions, learn about their underpinnings, and apply the right approach for optimum performance in real-world programs.

This book discusses the Clojure language in the light of performance factors that you can exploit in your own code.

You will also learn about hardware and JVM internals that also impact Clojure’s performance. Key features include performance vocabulary, performance analysis, optimization techniques, and how to apply these to your programs. You will also find detailed information on Clojure's concurrency, state-management, and parallelization primitives.

This book is your key to writing high performance Clojure code using the right abstraction, in the right place, using the right technique.

  • See how the hardware and the JVM impact performance
  • Learn which Java features to use with Clojure, and how
  • Deep dive into Clojure's concurrency and state primitives
  • Discover how to design Clojure programs for performance

Shantanu Kumar

Shantanu Kumar is a software developer living in Bengaluru, India. He works with Concur Technologies as a principal engineer, building a next-generation stack in Clojure. He started learning computer programming when he was at school, and has dabbled in several programming languages and software technologies. Having used Java for a long time, he discovered Clojure in early 2009 and has been a fan of it ever since.

When not busy with programming or reading up on technical stuff, he enjoys reading non-fiction and cycling around Bengaluru. Shantanu is an active participant in The Bangalore Clojure Users Group, and contributes to several open source Clojure projects on GitHub. He is also the author of the first edition of the book Clojure High Performance Programming, Packt Publishing.
