I've checked TotalUsedPages in ignite.dataRegionMetrics(), it is found
that the logic of this metric is consistent with OffheapUsedSize, that
is, the value will not be updated after data deletion.

Hello, you can check out "TotalUsedPages" and "TotalUsedSize" metrics
that can be found in the Data Region metrics. However, please keep in
mind that this does not take page fragmentation into account.

Hi team,
We found that if the delete operation is executed, the memory
space corresponding to the data will not be released, and this
space will be reused later.
Therefore, metrics such as OffheapUsedSize will become inaccurate.
So, how to calculate the exact amount of memory occupied by data
in a cache or a dataregion?
