Apache CouchDB is an open-source, document-oriented NoSQL database that uses JSON to store data. It features a RESTful HTTP API for accessing and querying data, making it well-suited for web and mobile applications. As an open-source solution, CouchDB serves as an alternative to other NoSQL databases such as MongoDB, RavenDB, and Amazon DocumentDB, particularly for applications that benefit from CouchDB’s multi-master replication and offline-first capabilities.
Key features include:
- Multi-Primary Replication: Enables seamless data synchronization across multiple CouchDB instances, making it suitable for distributed and offline-first applications.
- Scalability: Designed to scale horizontally, accommodating both big data and mobile applications.
- HTTP/JSON API: Provides a simple and intuitive interface for interacting with the database.
- Offline-First Applications: Supports building applications that can function offline and synchronize data when connectivity is restored.
- Fault Tolerance: Built for reliability, ensuring data availability even in the event of node failures.
Use cases include mobile applications, content management systems, and distributed data storage.
