Book Description:
Learn how to design complex, correct programs and fix problems before writing a single line of code. This book is a practical, comprehensive resource on TLA+ programming with rich, complex examples. Practical TLA+ shows you how to use TLA+ to specify a complex system and test the design itself for bugs.
You’ll learn how even a short TLA+ spec can find critical bugs. Start by getting your feet wet with an example of TLA+ used in a bank transfer system, to see how it helps you design, test, and build a better application. Then, get some fundamentals of TLA+ operators, logic, functions, PlusCal, models, and concurrency. Along the way you will discover how to organize your blueprints and how to specify distributed systems and eventual consistency.
Finally, you’ll put what you learn into practice with some working case study applications, applying TLA+ to a wide variety of practical problems: from algorithm performance and data structures to business code and MapReduce. After reading and using this book, you’ll have what you need to get started with TLA+ and how to use it in your mission-critical applications.
What You’ll Learn
Read and write TLA+ specifications
Check specs for broken invariants, race conditions, and liveness bugs
Design concurrency and distributed systems
Learn how TLA+ can help you with your day-to-day production work
Who This Book Is For
Those with programming experience who are new to design and to TLA+.

Abstract
As used in practice, traditional consensus algorithms require three message delays before any process can learn the chosen value. Fast Paxos is an extension of the classic Paxos algorithm that allows the value to be learned in two message delays. How and why the algo-rithm works are explained informally, and a TLA+ speci¯cation of the
algorithm appears as an appendix.
