And another thing: In a distributed system, must there really be any functional difference between RAM and disk memory? Of course, disk access is magnitudes slower than accessing RAM, but as I see it, at least theoretically, in a distributed system RAM could be made to function as a permanent storage.
Think of a single huge distributed virtual memory where data is stored in a duplicated and fail-safe way. Then the disk space would only be used for swapping memory pages to and from faster memory such as RAM (and in the future maybe even other forms of fast memory). Only at the very lowest level (Distributed OS 'kernel' level) would developers need to know if some chunk of memory is physically stored on disk or on some other form of memory. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
