Getting Started with CockroachDB

By: Kishen Das Kondabagilu Rajanna

Overview of this book

Getting Started with CockroachDB will introduce you to the inner workings of CockroachDB and help you to understand how it provides faster access to distributed data through a SQL interface. The book will also uncover how you can use the database to provide solutions where the data is highly available. Starting with CockroachDB's installation, setup, and configuration, this SQL book will familiarize you with the database architecture and database design principles. You'll then discover several options that CockroachDB provides to store multiple copies of your data to ensure fast data access. The book covers the internals of CockroachDB, how to deploy and manage it on the cloud, performance tuning to get the best out of CockroachDB, and how to scale data across continents and serve it locally. In addition to this, you'll get to grips with fault tolerance and auto-rebalancing, how indexes work, and the CockroachDB Admin UI. The book will guide you in building scalable cloud services on top of CockroachDB, covering administrative and security aspects and tips for troubleshooting, performance enhancements, and a brief guideline on migrating from traditional databases. By the end of this book, you'll have gained sufficient knowledge to manage your data on CockroachDB and interact with it from your application layer.

Chapter 3: Atomicity, Consistency, Isolation, and Durability (ACID)

In the Chapter 2, How Does CockroachDB Work Internally, we learned about the different layers of CockroachDB. In this chapter, we will learn about what ACID is, its importance, and what the ACID guarantees that CockroachDB provides are.

ACID guarantees the following things:

  • Atomicity: This is achieved through the notion of a transaction, in which all the statements within a transaction are executed as a single unit. So, either all of them succeed or fail together.
  • Consistency: The database state should be consistent before and after a transaction is executed and should ensure that the database constraints are never violated.
  • Isolation: Multiple transactions can get executed independently at the same time, without running into each other.
  • Durability: Changes, once committed, always remain intact, irrespective of any system or network failures.

The following topics will be covered in this...
