Hi Mike, static variables are a useful way to cache short term data.
They will last as long as the instance lasts which is hard to
predict. I read some time ago that there is an undocumented limit of
about 100MB of memory per instance.

On the dev server, I have a singleton DAO that encapsulates all logic
relating to the datastore and memcache. I was surprised to find that
the singleton persists between requests, and will generally go on
existing until I restart the dev environment. Does this reflect
production app engine behavior? If so, is there any documentation for
when/how objects in app engine persist and/or are destroyed between
requests?
Thanks,
Mike
