FUSE Driver for Riak

WARNING!!! This is a toy. Do not point it at a cluster you care about. You have been warned.

This proof-of-concept will mount your Riak cluster to your *nix filesystem, and allow you to browse the keyspace using standard tools like ls, cd, cat, etc…

Prerequisites

• FUSE drivers for your OS
• sudo gem install rubytree ripple

Installation

git clone http://github.com/johnthethird/riak-fuse.git
cd riak-fuse
sudo ./riak-fuse.rb -b bucket1,bucket2
(Then, in another terminal...)
cd /tmp/riak
ls

Notes

• You must specify your bucket names with the -b option. See -h for other options.
• Only reading of keys has been implemented, not writing.
• If your keys look like /foo/bar/logo.png then you will be able to navigate them like you would a directory structure. If your keys dont look like that, then they will show up all in the root directory.
• This script will ask Riak to list all keys, so beware if your buckets have too many keys.

JSAWK

If your keys contain JSON data, check out JSAWK for a really cool way to manipulate it from the command line. For example, if you had it and riak-fuse installed, you could do things like:

cat /mnt/riak/users/* | jsawk 'if (this.city != "Paris") return null'

This code would output the records of users that live in Paris. This is just scratching the surface of what jsawk can do.
