ArangoDB

We recently started a new open source project - a nosql database called AvocadoDB which became ArangoDB in May 2012. The current stable version of ArangoDB is 1.0. A multi server version is planned for the end of 2012. For details see the roadmap.

Key features include:

• Schema-free schemata let you combine the space efficiency of MySQL with the performance power of NoSQL
• Use ArangoDB as an application server and fuse your application and database together for maximal throughput
• JavaScript for all: no language zoo, you can use one language from your browser to your back-end
• ArangoDB is multi-threaded - exploit the power of all your cores
• Flexible data modeling: model your data as combination of key-value pairs, documents or graphs - perfect for social relations
• Free index choice: use the correct index for your problem, be it a skip list or a n-gram search
• Configurable durability: let the application decide if it needs more durability or more performance
• No-nonsense storage: ArangoDB uses all of the power of modern storage hardware, like SSD and large caches
• Powerful query language (AQL) to retrieve data
• It is open source (Apache Licence 2.0)

Compilation

Please check the Installation Manual for installation and compilation instructions.

Mac OS X Hints

On Mac OS X you can install ArangoDB using the packagemanager Homebrew:

• brew install arangodb (use --HEAD in order to build ArangoDB from current master)

This will install ArangoDB and all dependencies. Note that the server will be installed as

/usr/local/sbin/arangod

The ArangoDB shell will be install as

/usr/local/bin/arangosh

First Steps

Start the server:

> mkdir /tmp/vocbase
> bin/arangod /tmp/vocbase

2012-03-30T12:54:19Z [11794] INFO Have Fun!

Start the shell in another windows:
