David, I recently modified my memcached, sharded counter system to handle various datastore exceptions: http://billkatz.com/2008/10/Fault-tolerant-counters-for-App-Engine You can look at or copy the open source code referenced in that article. It also depends on your app requirements. The above counter shouldn't be used for banking, for example, because if there are simultaneous memcache and datastore errors, you lose pending increments. But if you want something that minimizes the impact of exceptions for things like votes, it's a reasonable approach. -Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
