No.  All that is being streamed is a gzipped csv file of aggregated
datavalues or aggregated indicator values from the datamart.  I should
check do we have any dataMart theme in our api .. I don't think we do
(yet).

So I guess if we were to think generally, we should think of different
useful api methods for accessing (slices of) our datamart.  Currently
I am happy to think quite primitively to just move the current actions
across.  But with a placeholder for more refined ideas we can
introduce later.  So I am thinking of something like a
DataMartValueController for want of a better name.  And getting the
actual data in exactly the same way I currently do - using a fairly
finely tuned jdbc resultset iterator as these datamart dumps can get
quite large.
