Sure, but that hardly makes it not "usable". Considering the price of
RAM these days, having enough RAM to hold the database (distributed over
the entire cluster) is perfectly acceptable for quite a few people.

(Another deficiency is in 4.0, predicates in queries would not be pushed
down to storage nodes -- so you had to stream the *entire* table over
the network, and then apply the WHERE clause at the frontend query node.
That is fixed in 5.0, though.)
