RethinkDB - ArchWiki

# RethinkDB

RethinkDB is a document-oriented database similar to MongoDB but aims to overcome scalability and practical limitation of the latter. [1] [2] RethinkDB is built to store JSON documents, and scale to multiple machines with very little effort. It has a pleasant query language that supports really useful queries like table joins and group by, and is easy to setup and learn.

## Installing RethinkDB

Install rethinkdb from official repository.

Now you can start rethinkdb from command-line:

    # rethinkdb

Or instead you can run it as systemd service. Enable default rethinkdb instance as

    # systemctl enable rethinkdb@default

and start it:

    # systemctl start rethinkdb@default

Admin UI will be available at 8080 port.

## Configuring RethinkDB

RethinkDB has multi-instance support, which means you can run several independent database instances at the same machine. Systemd service also supports multi-instance configuration.

To create a new RethinkDB instance create its configuration file:

    # cd /etc/rethinkdb
    # cp default.conf.sample instances.d/<NAME>.conf

where <NAME> is the name of you configuration that you'll going to use later. Change configuration options in the new config file. Then start the service:

    # systectl enable rethinkdb@<NAME>
    # systectl start rethinkdb@<NAME>

'default' instance is created at installation time for your convinence. Its data is stored in /var/lib/rethinkdb/default
