Hi Vinny,
Thanks for the pointers. My app uses Angular and some jQuery so
LocalStorage should be a breeze I guess. What I am really looking for is
some insight into how to minimize the app engine related cost of keeping
the client side cache (relatively) up to date.
The design I have so far is to have a separate ModTime class, which has a
single DateTimeProperty with auto_now=True. ModTimes are attached to
entities with the parent relation so that I can construct a ModTime key
from the entity key as ndb.Key('ModTime', 'modtime', parent=entity_key).
The client can then easily ask whether the locally cached value is up to
date. Datastore cost is minimized as only the ModTime entity needs to be
read.
