Good suggestions about how to replicate data across all of the instances were given. If you don’t feel satisfied with these, I believe that if you elaborate more on your use case and explain what you are specifically trying to accomplish (why do you want to replicate data across all of your instances) you might get more suggestions, but you might need to do this in Stack Overflow <https://stackoverflow.com/> as it would be out of the general scope and by posting your question on Stack Overflow, you will gain access to a large number of experts as well.
Alternatively, as Katayoon previously mentioned, you can file a feature request via Issue Tracker <https://cloud.google.com/support/docs/issue-trackers> and the App Engine Team will evaluate your request. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
