RethinkDB

What is RethinkDB?

Open-source database for building realtime web applications
NoSQL database that stores schemaless JSON documents
Distributed database that is easy to scale
High availability database with automatic failover and robust fault tolerance

RethinkDB is the first open-source scalable database built for realtime applications. It exposes a new database access model, in which the developer can tell the database to continuously push updated query results to applications without polling for changes. RethinkDB allows developers to build scalable realtime apps in a fraction of the time with less effort.

Not sure what types of projects RethinkDB can help you build? Here are a few examples:

Build a realtime liveblog with RethinkDB and PubNub
Create a collaborative photo sharing whiteboard
Build an IRC bot in Go with RethinkDB changefeeds
Look at cats on Instagram in realtime
Watch how Platzi uses RethinkDB to educate

Quickstart

For a thirty-second RethinkDB quickstart, check out rethinkdb.com/docs/quickstart.

Or, get started right away with our ten-minute guide in these languages:

Besides our four official drivers, we also have many third-party drivers supported by the RethinkDB community. Here are a few of them:

C#/.NET: RethinkDb.Driver, rethinkdb-net
C++: librethinkdbxx
Clojure: clj-rethinkdb
Elixir: rethinkdb-elixir
Go: GoRethink
Haskell: haskell-rethinkdb
PHP: php-rql
Rust: reql
Scala: rethink-scala

Building

First install some dependencies. For example, on Ubuntu or Debian:

sudo apt-get install build-essential protobuf-compiler \
    # python \  # for older distros
    python3 python-is-python3 \
    libprotobuf-dev libcurl4-openssl-dev \
    libncurses5-dev libjemalloc-dev wget m4 g++ libssl-dev

Generally, you will need

GCC or Clang
Protocol Buffers
jemalloc
Ncurses
Python 2 or Python 3
libcurl
libcrypto (OpenSSL)
libssl-dev

Then, to build:

./configure --allow-fetch
# or run ./configure --allow-fetch CXX=clang++

make -j4
# or run make -j4 DEBUG=1

sudo make install
# or run ./build/debug_clang/rethinkdb

See WINDOWS.md and mk/README.md for build instructions for Windows and FreeBSD.
