Dmitry Werner updated IGNITE-29032:
-----------------------------------
Description:
Improving the guarantees of the pageEviction 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 pageEviction and
expiryPolicy mechanisms operate simultaneously.
