A friend of mine recently asked if RavenDB could be used in something
more write heavy. Specifically, he wanted to continuously read values
from a sensor and be able to query on the data in some meaningful way.

I put together a demo application that does exactly that, and thought
I would share with the community. If you are interested, you can
check it out here:

But please don't underestimate the power of rrdtool!

Don't know much about rrdtool. Does it offer an abstraction layer for
persistence that one could sit it on top of RavenDB?

Another pro tool for this kind of stuff is Microsoft Stream Insight
that ships as part of SQL Server, but I was wanting a pure NoSQL
implementation.

Quite the opposite - it offers concrete implementation of very efficient time series storage, processing, retrieval and graph drawing. Everything you would want to have, in a single exe.
