Hi Jason,
Thanks for your answer.
However I forgot to specify that I'd like to know the number of
entities of a specific kind which have a specific value in one of its
field (for example number of Student which attend a specific course).
It looks like Statistics don't fit this aim, not that
You can also use the new datastore statistics API, which is probably faster
although I haven't timed this myself:
