> Key: IGNITE-13726
> URL: https://issues.apache.org/jira/browse/IGNITE-13726
> Project: Ignite
> Issue Type: New Feature
> Reporter: Aleksey Plekhanov
> Assignee: Aleksey Plekhanov
> Priority: Major
> Labels: IEP-35, iep-62
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Currently, we can't determine how many hot (touched recently) and cold pages we have in the page-memory. This information can be helpful for data region size tuning and can show the effectiveness of the page replacement algorithm.
> Such information can be represented as a histogram showing the count of pages last touched in each time interval.
