CockroachDB vs FaunaDB: What are the differences?

Introduction

CockroachDB and FaunaDB are both distributed databases that offer unique features and functionalities. In order to make an informed decision on which database to use for your project, it is essential to understand the key differences between them.

1. Architecture: CockroachDB is a distributed SQL database that is fully ACID-compliant, providing horizontal scalability and fault tolerance. It is designed to handle large amounts of data and is suitable for applications that require strong consistency. FaunaDB, on the other hand, is a globally distributed database that offers a serverless approach to development. It focuses on providing a flexible data model and supports multi-region deployments with ease.

2. Data Model: CockroachDB uses a traditional SQL-based data model, which is well suited for applications that require complex querying and transactions. It supports standard SQL syntax and data types, making it easy for developers familiar with SQL to work with the database. In contrast, FaunaDB uses a schemaless and document-oriented data model inspired by GraphQL. It allows for flexible and dynamic data structures, making it ideal for applications with rapidly changing data requirements.

3. Consistency Model: CockroachDB offers strong consistency guarantees by default, ensuring that all replicas of the data are always up to date. This makes it a good choice for applications that require strict consistency and do not tolerate stale data. FaunaDB, on the other hand, provides tunable consistency levels, allowing developers to choose between strong and eventual consistency based on their application's requirements.

4. Ease of Use: CockroachDB is relatively easy to set up and manage, with a focus on simplicity and operational efficiency. It provides a user-friendly SQL interface that is familiar to many developers, making it easy to get started with the database. FaunaDB, on the other hand, offers a fully managed service with automatic scaling and built-in security features. It is designed to be developer-friendly, allowing users to focus on building their applications without worrying about database management tasks.

Summary

In summary, CockroachDB is a distributed SQL database with strong consistency and horizontal scalability, while FaunaDB is a globally distributed database with a flexible data model and serverless approach to development. The choice between the two databases ultimately depends on the specific requirements of your application and the level of control and flexibility you require.
