RethinkDB is a free and open-source, distributed document-oriented database originally created by the company of the same name. The database stores JSON documents with dynamic schemas, and is designed to facilitate pushing real-time updates for query results to applications. Initially seed funded by Y Combinator in June 2009,[2] the company announced in October 2016 that it had been unable to build a sustainable business and its products would in future be entirely open-sourced without commercial support.[3]

The CNCF (Cloud Native Computing Foundation) then purchased the rights to the RethinkDB source code and contributed it to the Linux Foundation.[4]

History

RethinkDB was founded in 2009, and open-sourced at version 1.2 in 2012.[5] In 2015, RethinkDB released version 2.0, announcing that it was production-ready.[6] On October 5, 2016, the company announced it was shutting down, transitioning members of its engineering team to Stripe, and would no longer offer production support.[7][8] On February 6, 2017, The Cloud Native Computing Foundation purchased the rights to the source code and relicensed it under the Apache License 2.0.[9][10]

ReQL

RethinkDB uses the ReQL query language, an internal (embedded) domain-specific language officially available for Ruby, Python, Java[11] and JavaScript (including Node.js). It has support for table joins, groupings, aggregations and functions. There are also unofficial, community-supported drivers for other languages, including C#, Clojure, Erlang, Go, Haskell, Lua, and PHP.

Popularity

According to the DB-Engines ranking, as of February 2016, it was the 46th most popular database.[12]

Comparison with other document databases

A distinguishing feature of RethinkDB is the first class support for real-time change feeds. A change query returns a cursor which allows blocking or non-blocking requests to keep track of a potentially infinite stream of real-time changes.[13]

Fork

Due to seeming stagnation, RethinkDB was forked by members of the community on May 17, 2018. [14] The new project, called RebirthDB, is also hosted on GitHub. The project later merged back with the original repository.[15]
