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.
