What is RethinkDB?
RethinkDB is an open-source database designed specifically for realtime web applications. It pushes JSON data to applications in realtime, eliminating the traditional polling approach that often leads to slow performance, scalability issues, and maintenance challenges. This architecture makes building reactive web and mobile apps, multiplayer games, realtime marketplaces, streaming analytics platforms, and connected device systems dramatically easier.
The database supports querying JSON documents with popular programming languages like Python, Ruby, and Node.js, and integrates seamlessly with realtime technologies such as Socket.io or SignalR. It features a robust distributed architecture with an optimized buffer cache and advanced storage engine, offering capabilities like joins for expressing relationships, location-aware app development, multimedia and time-series data storage, analytics with aggregation and map/reduce, and flexible indexing. Scaling is simplified through an intuitive web UI for sharding and replication, with live cluster monitoring via a comprehensive API.
