> It would be great if we can have a new type of page replacement policy that does not affect index pages when persistence is on. So, the index pages always will be in-mem and that will improve an overall system performance for random reads with persistence is on.
> For instance, MongoDB works that way. It always keeps all indexes in-mem.
