The SDK 1.3.1 Prerelease adds a memcache.grab_tail() function, it's
very useful for counting, but why it only returns values, not a (key,
value) pair list or dict?
If a (key, value) pair list is available to retrieve, I think counting
would be even easier like this:
1) add a page view for article 1:
memcache.incr('1', namespace='article counter', initial_value=0)
2) add a page view for article 2:
memcache.incr('2', namespace='article counter', initial_value=0)
3) use cron jobs to update memcache counter to datastore:
counter = memcache.grab_tail(10, 'article counter')
for article_id, pv in counter:
# update to datastore
But now, counter only contains pv, no article_id in it, so I can't
find a simple way to implement the same scenario.
