Introduction

CockroachDB is a cloud-native, distributed SQL database built for high availability, scalability, and resilience. Its unique architecture mimics the behavior of a cockroach—able to survive and adapt under adverse conditions—by providing automatic failover, replication, and recovery. Designed for modern, globally distributed applications, CockroachDB simplifies data management across regions while ensuring strong consistency and transactional guarantees.

Prerequisites

• Basic knowledge of relational databases and SQL.
• Familiarity with distributed systems and cloud architecture.
• Understanding of ACID properties and database transactions.
• A development environment to interact with CockroachDB.
