[jira] [Created] (IGNITE-7627) Introduce a new eviction policy to avoid eviction of Index pages

             Summary: Introduce a new eviction policy to avoid eviction of Index pages
                 Key: IGNITE-7627
                 URL: https://issues.apache.org/jira/browse/IGNITE-7627
             Project: Ignite
          Issue Type: Improvement
          Components: persistence
            Reporter: Alexey Popov


It would be great if we can have a new type of eviction 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.
