I'm not sure I understood. Changing an index from asc. to desc. does not require a re-put, because the asc. index already exists? There's also related question I never understood. If the keys already have an asc. index, why can't that index be used in reverse for desc. queries? Due to the CPU / disk caches being optimized for forward reading? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
