Concurrent Patterns and Best Practices

By: Atul S. Khot

Overview of this book

Selecting the correct concurrency architecture has a significant impact on the design and performance of your applications. Concurrent design patterns help you understand the different characteristics of parallel architecture to make your code faster and more efficient. This book will help Java developers take a hands-on approach to building scalable and distributed apps by following step-by-step explanations of essential concepts and practical examples. You’ll begin with basic concurrency concepts and delve into the patterns used for explicit locking, lock-free programming, futures, and actors. You’ll explore coding with multithreading design patterns, including master, slave, leader, follower, and map-reduce, and then move on to solve problems using synchronizer patterns. You'll even discover the rationale for these patterns in distributed and parallel applications, and understand how future composition, immutability, and the monadic flow help you create more robust code. By the end of the book, you’ll be able to use concurrent design patterns to build high performance applications confidently.

So, this was a whirlwind tour of the world of concurrency, dear reader. It served more as a memory refresher for many of the things you probably knew already.

We saw that concurrency is very common in the real world, as well as in the software world. We looked at the message passing and shared memory models, and saw how many common themes drive these two models.

If the shared memory model uses explicit locking, a host of problems emerge. We discussed race conditions, deadlocks, critical sections, and heisenbugs.

We wrapped up with a discussion of asynchronicity, the actor paradigm, and the software transactional memory. Now that we have all this background knowledge, in the next chapter, we will look at some core concurrency patterns. Stay tuned!
