AFAIK there's no way of being informed about the instantiation of another instance or change on a memcache value without accessing the memcache itself.
The best solution is to use vm memory cache only for data that is going to be unchanged, changed only during known specific intervals, or that you can accept that it will be occasionally inconsistent. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
