About
RethinkDB is an open-source, scalable NoSQL database designed for building realtime applications. It pushes JSON data to connected clients automatically when data changes, eliminating the need for polling. It supports a rich query language across multiple programming languages and includes clustering, sharding, and a built-in web UI.
Problem
Traditional databases require apps to poll for data changes, making realtime apps slow, unscalable, and complex to maintain.
For
developers building realtime web and mobile applications
How it works
RethinkDB uses a changefeeds feature that continuously pushes updated query results to applications in realtime whenever the underlying data changes.
