Documentation
RethinkDB Cloud provides a hosted RethinkDB database instance. It is fully managed and elastic, i.e., you can add or remove storage instantly and without the loss of data.
Getting started
Start by installing the add-on:
$ heroku addons:create rethinkdb
Once the add-on has been added you’ll notice new variables in
heroku config
:
$ heroku config
...
RETHINKDB_HOST: bf1036d9-c2ba-4ae3-ad58-8d14a50117b3.rdb.lf.memcachier.com
RETHINKDB_NAME: bf1036d9-c2ba-4ae3-ad58-8d14a50117b3
RETHINKDB_PASSWORD: 078c1d4cd2dec203d2db05f788fe5d3a09393bb9
RETHINKDB_PORT: 28015
RETHINKDB_USERNAME: bf1036d9-c2ba-4ae3-ad58-8d14a50117b3
...
These variables are required when configuring your client to connect to your RethinkDB instance.
Node.js
Install the driver with npm:
$ npm install rethinkdb
You can use the drivers from Node.js like this:
r = require("rethinkdb");
r.connect(
{
host: process.env.RETHINKDB_HOST || "localhost",
port: process.env.RETHINKDB_PORT || 28015,
username: process.env.RETHINKDB_USERNAME || "admin",
password: process.env.RETHINKDB_PASSWORD || "",
db: process.env.RETHINKDB_NAME || "test",
},
function (err, conn) {
if (err) throw err;
r.tableCreate("tv_shows").run(conn, function (err, res) {
if (err) throw err;
console.log(res);
r.table("tv_shows")
.insert({ name: "Star Trek TNG" })
.run(conn, function (err, res) {
if (err) throw err;
console.log(res);
});
});
},
);

Python
Install the driver with pip:
$ pip install rethinkdb
You can use the drivers from Python like this:
from rethinkdb import r
r.connect(host=os.getenv('RETHINKDB_HOST', 'localhost'),
port=os.getenv('RETHINKDB_PORT', 28015),
user=os.getenv('RETHINKDB_USERNAME', 'admin'),
password=os.getenv('RETHINKDB_PASSWORD', ''),
db=os.getenv('RETHINKDB_NAME', 'test')).repl()
r.table_create('tv_shows').run()
r.table('tv_shows').insert({ 'name': 'Star Trek TNG' }).run()

Ruby
Install the driver with gem:
$ gem install rethinkdb
You can use the drivers from Ruby like this:
require 'rubygems'
require 'rethinkdb'
include RethinkDB::Shortcuts
r.connect(:host => ENV['RETHINKDB_HOST'] || 'localhost',
:port => ENV['RETHINKDB_PORT'] || 28015,
:user => ENV['RETHINKDB_USERNAME'] || 'admin',
:password => ENV['RETHINKDB_PASSWORD'] || '',
:db => ENV['RETHINKDB_NAME'] || 'test', ).repl
r.table_create('tv_shows').run
r.table('tv_shows').insert({ 'name'=>'Star Trek TNG' }).run

Java
Installation
Maven
If you’re using Maven, add this to your pom.xml
file:
<dependencies>
<dependency>
<groupId>com.rethinkdb</groupId>
<artifactId>rethinkdb-driver</artifactId>
<version>2.4.1</version>
</dependency>
</dependencies>
Gradle
If you’re using Gradle, modify your build.gradle
file:
dependencies {
compile group: 'com.rethinkdb', name: 'rethinkdb-driver', version: '2.4.1'
}
Ant
If you’re using Ant, add the following to your build.xml
:
<artifact:dependencies pathId="dependency.classpath">
<dependency groupId="com.rethinkdb" artifactId="rethinkdb-driver" version="2.4.1" />
</artifact:dependencies>
SBT
If you’re using SBT, add the following to your build.sbt
:
libraryDependencies += "com.rethinkdb" % "rethinkdb-driver" % "2.4.1"
Usage
You can use the drivers from Java like this:
import com.rethinkdb.RethinkDB;
import com.rethinkdb.gen.exc.ReqlError;
import com.rethinkdb.gen.exc.ReqlQueryLogicError;
import com.rethinkdb.model.MapObject;
import com.rethinkdb.net.Connection;
public static final RethinkDB r = RethinkDB.r;
Map<String,String> envs = System.getenv();
Connection conn = r.connection()
.hostname(envs.getOrDefault("RETHINKDB_HOST","localhost"))
.port(Integer.parseInt(envs.getOrDefault("RETHINKDB_PORT","28015")))
.user(envs.getOrDefault("RETHINKDB_USERNAME","admin"), envs.getOrDefault("RETHINKDB_PASSWORD",""))
.dbname(envs.getOrDefault("RETHINKDB_NAME","test"))
.connect();
r.tableCreate("tv_shows").run(conn);
r.table("tv_shows").insert(r.hashMap("name", "Star Trek TNG")).run(conn);
