CockroachDB is a distributed, transactional, relational, cloud native SQL database system. That’s quite a mouthful! But in short, CockroachDB leverages both the strengths of the previous generation of relational database systems—strong consistency, the power of SQL, and the relational data model—and the strengths of modern distributed cloud principles. The result is a database system that is broadly compatible with other SQL-based transactional databases but delivers much greater scalability and availability. In the second edition of this popular hands-on guide, software developers, architects, and DevOps/SRE teams will learn how to use CockroachDB to create applications that scale elastically and provide seamless delivery for end users while remaining indestructible. Data engineers and database administrators will also learn how to migrate existing applications to CockroachDB's performant, cloud native data architecture. If you're familiar with distributed systems, you'll quickly discover the benefits of strong data correctness and consistency guarantees, as well as optimizations for delivering ultra-low latencies to globally distributed end users.
