Riak scenarios

We're building an application right now, that will provide analytics/reports
to customers, using Riak as the storage solution.
I actually spoke with Basho prior to committing to Riak, explained that we
needed to be able to scale well with this solution, that it was geared to
providing analytics & reports, etc, and they (Basho) supported this effort
using Riak.

Our application processes incoming data, transforms it into Riak-friendly
objects, performs all necessary calculations (and stores the values) during
transformation, and then stores into Riak. Maybe this process is why Basho
didn't say "don't use Riak".

I can totally see that attempting to store straight SQL data into Riak and
then running ad-hoc queries would be quite inappropriate, but otherwise I'm
uncertain how Riak wouldn't suffice as a solution. As we're pre-emptively
storing what we would normally query "ad-hoc", that's not an issue for our
product.


In case someone is unsure of how I'm defining data analytics:
http://en.wikipedia.org/wiki/Data_analytics

We're essentially building a "business intelligence" product for
universities.
