Not necessarily; you may be betting that it's more *efficient* to do the
parsing on a bunch of lightly loaded clients than your server. Even if
you're using the same code this may be a big win.
it's a lot easier to throw hardware at the problem by spliting your
incomeing data between multiple machines and have them all working in
parallel throwing the data at one database then it is to throw more
hardware at the database server to speed it up (and yes, assuming that MPP
splits the parseing costs as well, it can be an answer for some types of
systems)
