RethinkDB is a document-oriented database similar to MongoDB but aims to overcome scalability and practical limitation of the latter.   RethinkDB is built to store JSON documents, and scale to multiple machines with very little effort. It has a pleasant query language that supports queries such as table joins and group by. It is easy to setup and learn. For more detailed information, see the official homepage.
Install AUR from the official repositories.
Create and set user rights for RethinkDB folder:
# mkdir /var/lib/rethinkdb/default # chown -R rethinkdb:rethinkdb /var/lib/rethinkdb/
Now you can start
rethinkdb from the command-line:
RethinkDB's admin UI is now available on port 8080.
RethinkDB has multi-instance support, which means you can run several independent database instances on the same machine. The systemd service also supports multi-instance configuration.
To create a new RethinkDB instance, create its configuration file:
# cd /etc/rethinkdb # cp instances.d/default.conf instances.d/Name.conf
where Name represents the configuration you will be using later. Change the configuration options in the new config file. Then start/enable
The 'default' instance is created at installation time for your convenience. Its data is stored in
