> Improving the guarantees of the page eviction mechanism on in-memory data regions to eliminate the possibility of data region overflow. For example, when inserting large records, or during batch inserts via putAll.
> The mechanism should take into account the volume of data being inserted and, accordingly, must ensure that old records are evicted in the same volume.
> Currently, there is a possible scenario in which an in-memory data region with the pageEviction mechanism enabled may overflow. For example, when inserting large records, or during batch inserts via putAll, the data region can overflow.
> The likelihood of such an event increases when the page eviction and expiry policy mechanisms operate simultaneously.
