I'm using memcache.set_multi() / add_multi() for caching DataStore
data. Code is something like following:
users = User.all().query(....).fetch(...)
mapping = {}
for u in users:
mapping[str(u.key())] = u
memcache.set_multi(mapping, namespace='synccache')
It seems that set_multi/add_multi returns correct value and there's no
error logs, error messages, nor exception. However, I can't retrieve
them with memcache.get_multi().
Thanks,
Kazuho
