Super simple way to get your bucket's data as CSV (I use it to build data frames in R easier)
…ledge; especially when it comes to manually wrapping json values with quotes when you have a fantastic encoding library nearby in mochijson2.

Riak CSV This module aims to give you a simple way to get your buckets as csv dumps. The main motivation behind this was to be able to create data frames in R a little easier from riak. One could just write an R-package to encode the json, etc...but IMHO the less of that you have R do, the more memory you'll have for your work. Caveats Obviously CSV requires that your rows be uniform. Therefore, if you have a bucket with non uniform entries it's going to get hairy. For now the first item (in the bucket) will have its properties extracted and those will be used to pluck all the subsequent values. Currently not reading riak's host/port from config. Currently has some functions with an arity of 4/5 - this will be refactored to use a record instead. It's bugging me, so surely it'll bother you and the rest of the internet. Installation You can install this thing two ways. You can either add it to your riak rebar.config and reltool.config by looking at the example snippet meow: https://gist.github.com/817832 Or! You can just compile it yourself and launch it by attaching to your riak cluster and executing the lovely and talented: application:start(riak_csv)
