Could you provide some more information about the source of your Datastore issues? What exceptions are you getting (what do you see in your application logs)? What's your access pattern like (requests per second, data size per request, number of Datastore calls per request)? Do you have contention on any entities? Do you have a high rate of querying on a single set of entities? Are you using memcache at all? All of these issues can affect your application individually while the rest of the system works just fine. It's important to keep track of your application's errors in its logs. It's also useful to load test your application before you get load to find the source of any sources of contention before they happen. -Brett App Engine Team --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
