Hi all,

Thrilled about the AppEngine Java support and reading up on the
platform, etc.   Very exciting stuff.

Information about the various limits imposed by the system seems to be
a bit spread all over, is there anywhere one can go for a quick
rundown of *all* the various limits?

Naturally there's the quotas page[1], but then there are further
significant limits for the datastore[2], and neither of those pages
mentions that there is apparently a limit on the number of datastore
indices[3] -- a very important piece of information.  It also appears
that each static file in your app can be no more than 10MB[4].
There's some disagreement amongst pages as well; the overview page[5]
says the free accounts get 500MB of storage, but the quotas page
(presumably the more canonical of the two) says 1GB.  Apparently
requests must be satisfied within 30 seconds[4][5].  A user seemed to
say[6] in the group that there is a 1,000 file limit, but I haven't
found that one (yet!) from Google.  And it's not clear to me whether
it's 1GB of storage, total, or 1GB of datastore storage *plus* the
storage of your application files.

For clarity, this is not criticism disguised as a question.  I'm
really asking the question. :-)  Is this all pulled together somewhere
I've missed so far?  Apologies if I've overlooked the obvious, which
wouldn't surprise me.
