Protocol buffers don't have a specific type for sets. One workaround you could try would be to use something like map<int64, bool>, and just ignore the bool values, since that would give you a way of ensuring the int64 keys are unique. But I would guess it would be cleaner to go with Marc's suggestion and use a repeated field, and convert that to a Java Set when you need it.
