CockroachDB for SQL

1. Introduction

CockroachDB is a distributed SQL database designed for cloud-native applications. It offers strong consistency, high availability, and horizontal scalability, making it suitable for applications requiring resilience and performance across distributed environments.

2. Key Concepts

• **Distributed Architecture**: CockroachDB operates across multiple nodes, ensuring data is replicated and available even in case of failures.
• **SQL Compatibility**: CockroachDB uses standard SQL, allowing for easy migration from traditional SQL databases.
• **ACID Transactions**: It supports ACID transactions across distributed nodes, ensuring data integrity.
• **Geo-Partitioning**: Data can be partitioned based on geographical locations for improved latency and compliance.

3. Installation

To install CockroachDB, follow these steps:

1. Download the CockroachDB binary from the official website.
