Dmitriy Pavlov updated IGNITE-7627:
-----------------------------------
Description:
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.
