I don't expect this to be used by people wanting to host on shared infrastructure. This ought to be useful for anyone running anything from their own VPS to a small cluster (presuming no app they run requires more datastore than a single server can host). If it becomes a practical alternative, I expect we'd see alternate hosts for App Engine apps, using this or another datastore backend. > Still, GAE-J developers now have a reasonable alternative and maybe > some of your efforts can be applied to an all python version for BDB > (or zodb). > > Thanks! > -Tim > > On Apr 17, 9:59 am, Nick Johnson <arach...@notdot.net> wrote: > > > On Apr 17, 5:50 pm, johnP <j...@thinkwave.com> wrote: > > > > Quick question (I have not looked at your datastore at all yet) - > > > > Can using your datastore eliminate the limit of 1000 entities on a > > > fetch?
