Advancing the Realtime Web with RETHINKDB

RETHINKDB is a Open-source distributed database built to store JSON and scale with very little effort. Self compared with MongoDB, RETHINKDB are aiming to being developer friendly all the while maintaining an operations oriented Approach of being highly available and high scale.

Prior to version 1.16, original intentions from RETHINKDB is a system to push out changes from database level to Speciali Zed data stores like ElasticSearch or messaging systems. These were implemented as changefeeds, a-to-subscribe-change-notifications from the database. A client can subscribe to changes in a database table and get notified every time a change happens to it.

This feature is really well received and RETHINKDB decided to expand it-explicitly support realtime apps. Building Realtime apps in a truly scalable are not easy and RETHINKDB aims-to-change it. A client can subscribe to query results and would get a cursor that gets updated any time a change occurs in the database. RETHINKDB claims that thousands of concurrent changefeeds can run in parallel, all getting results within milliseconds lat Ency.

Comparing with realtime Sync Services like Firebase, PubNub and pusher, RETHINKDB offers better querying capabilities and Can push changes on queries and not just single documents. Also, RETHINKDB is a open-source system both at the protocol and implementation level. Finally, Rethinkdb ' s realtime push capabilities is architected for backend services, instead of the browser.

RETHINKDB also aims to integrate changefeeds with Meteor and the Volt to make sure it plays the well with realtime web frameworks. A working example of the realtime capabilities of RETHINKDB can be found as a realtime Instagram client for the Web, Capt Uring the latest cats from #catsofinstagram and plotting them on a map using geolocation. Rethinkdb ' s code is available on GitHub.
