----------------------------------
> MVCC Cache.size corner cases
> ----------------------------
>
> Key: IGNITE-9459
> URL: https://issues.apache.org/jira/browse/IGNITE-9459
> Project: Ignite
> Issue Type: Bug
> Components: mvcc
> Reporter: Ivan Pavlukhin
> Priority: Major
>
> 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.
