If you don't specify a key, Riak will choose one for you (base 62-encoded hash of something, last I checked). Is that not what you're trying to do?

The actual code in question (this is a simplification) is generating a GUID which can easily be stored as a string instead of an integer. Otherwise we'll just have to use some other term, your example is precisely what we're doing.

If you want to use a non-String value for the key, create a property of some other name and then use the "key_on" method which makes a defined property act as the key.
