It doesnt matter that some entities have a different schema to others. Drop the SQL mindset ;) So you just add the extra field, the next time you happen to modify that particular entity anyway. So the 'migration' happens, very slowly over time. Costs very little extra, because the write would of happened anyway. Each entity could have a 'version' value, which the code notes is 'outdated' and then updates it automatically. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
