>                 Key: IGNITE-9459
>                 URL: https://issues.apache.org/jira/browse/IGNITE-9459
>             Project: Ignite
>          Issue Type: Bug
>          Components: mvcc
>            Reporter: Ivan Pavlukhin
>            Priority: Major
>              Labels: mvcc_stabilization_stage_1

> During implementation of Cache.size for MVCC some corner cases were found. Attention must be put on:
> {{org.apache.ignite.internal.processors.cache.IgniteCacheOffheapManager#mvccRemoveAll}}
> {{org.apache.ignite.internal.processors.cache.IgniteCacheOffheapManager#mvccInitialValue}}
> {{mvccRemoveAll}} could erroneously decrement size when deleting version which was deleted (having {{newVersion}} committed).
> {{mvccInitialValue}} could increment value over already existing value from history during rebalance.
> It worth carefully reproduce both cases before making any fixes.
