Using only for Luwak

Hi Nicholas,

As much as we would love you to use Riak for your application, at this
point you're advised to do it without Luwak. As few weeks ago we
informed the list that we won't be actively developing Luwak [1]
following the forthcoming Riak 1.1 release. While it was a useful
piece of code conceptually, architecturally it proved problematic to
support and extend.  Dizzy provided some details on the specifics a
few days back [2].

On the topic of Riak's feasibility without Luwak for your use case,
how large are the files you were planning to store in it?
