Arakoon

Arakoon is a distributed key/value store with preference for consistency. More technically, it's a Multi-Paxos implementation (written in OCaml) running on top of TokyoCabinet.

Building Arakoon

For compilation instructions, see the COMPILING document. Information about the libraries we use is available in LIBRARIES.

Quickstart

Start by building Arakoon. To set up a single-node demo server, a basic configuration file is required, e.g.

$> cat single.ini
[global]
cluster = arakoon_0
cluster_id = ricky

[arakoon_0]
ip = 127.0.0.1
client_port = 4000
messaging_port = 4010
home = /tmp
log_level = info

Now, start the node using

$> ./arakoon.native -config single.ini --node arakoon_0

This starts a single node cluster for you to play with.

You can set and retrieve values from the command line using

$> ./arakoon.native -config examples/single.ini --set hello world
$> ./arakoon.native -config examples/single.ini --get hello
"world"

An overview of all command-line options is available by running arakoon.native --help.

Of course you want to use Arakoon from within a program. We provide OCaml, C and Python clients.

Releases

Arakoon releases are available from the releases page. Any 1.X branch corresponds to the development of releases in the 1.X series.

Have fun,

The Arakoon team
