Hi
Are these large queries and/or lot's of put's. Have you looked at
appstats
to see if your doing these operations efficiently ?
Are you utilising caching with memcache to reduce your need for
querying all the time ?
Are you doing batch fetch's on your query results rather than
iterating ?
I thought about using taskqueues, but it's important that I get the
result of the put() operation immediately. Maybe the new channel api
will help (release 1.4.0), so that I'll use task queues for put()
operations and push an info to the user once the operation result is
positive.
At the moment
Yes I've looked at appstats, looks alright so far.
Problem 1: put() operations (ajax request)
It's one put() operation per request.
Problem 2: queries (normal requests)
It's important that the results of these queries are up to date, so I
have to fetch them every time a user loads the
When a user loads my app for the first time, I exchange his facebook

Hi,

Hi
A single put ajax or otherwise shouldn't take to long, are you doing
the put inside transactions, with large entity groups? That could
cause problems. This isn't a big counter or something is it ? How long
is a single put taking ? and are you getting
a Datastore timeout or some other error ?
Probably. With some more thinking I got to this conclusion:
At first, an application can utilize up to 30 instances. After having
used all those instances for a few minutes, and it still isn't enough,
GAE will increase the maximum number of available instances to 40, and
