#appengine

oden_: good enough

good enough for 10K users, 100K, 1 Million, 10 million?

i have a simple android game and use a appengine as a backendï will memcache the leaderboard

are*

should certainly be good enough to start with

switching to private memcache is just a few button presses anyway

although of course you odds on getting evicted are higher than with private memcache
