It is only possible to use memcache or datastore from google on GAE.
Brent Pedersen implemented a memcache store class in his code.
Here is the implementation for google store. The only caveat in
original session file is the cleanup time is too long, deletion on GAE
store need to be executed on a per recorded basis.
class WebpySession(db.Model):
data = db.BlobProperty()
atime = db.DateTimeProperty(auto_now=True)
class GoogleStore(Store):
"""Google Datastore"""
def __init__(self, prefix="p"):
self.prefix=prefix
def __contains__(self, key):
return WebpySession.get_by_key_name(self.prefix+key) is not
None
def __getitem__(self, key):
try:
return
pickle.loads(WebpySession.get_by_key_name(self.prefix+key).data)
except AttributeError:
raise KeyError, key
def __setitem__(self, key, value):
r = WebpySession.get_or_insert(self.prefix+key)
r.data = pickle.dumps(value)
r.put()
def __delitem__(self, key):
try:
WebpySession.get_by_key_name(self.prefix+key).delete()
except AttributeError:
pass
def cleanup(self, timeout):
db.delete(WebpySession.all().filter('atime <',
datetime.datetime.now()-
datetime.timedelta(seconds=timeout)).fetch(CLEANUP_BATCH_SIZE))
