Build real-time Web apps with RethinkDB

The RethinkDB JSON database simplifies the development of applications that rely on real-time updates

You can even use RethinkDB changefeeds in conjunction with the ReQL monitoring APIs to retrieve a stream of live data. For example, you could build your own cluster monitoring tool that attaches a changefeed to the stats system table and uses the real-time updates to display a live graph of the read/write load.

RethinkDB 2.1, released earlier this month, introduces built-in support for automatic failover. The new feature enables high-availability clustering, reducing the risk of downtime. When a server with a primary replica experiences failure, the database servers with remaining replicas elect a new acting primary to takes its place until the original primary comes back online or is permanently removed from the cluster. Hardware failures or partial network outages will no longer compromise data availability as long as a majority of replicas remain online.

Install RethinkDB

RethinkDB runs on Linux and Mac OS X. A native Windows port is under active development, but is not yet available for download. You can visit the RethinkDB documentation for details about how to install the database. We provide APT and Yum repositories for Linux users and a pkg installer for OS X. You can also install RethinkDB with Docker or compile the source code from GitHub. To learn how to build an application, check out the 10-minute guide in our documentation.
