> Key: IGNITE-9591
> URL: https://issues.apache.org/jira/browse/IGNITE-9591
> Project: Ignite
> Issue Type: Task
> Components: mvcc
> Reporter: Roman Kondakov
> Priority: Minor
> Labels: mvcc_performance, performance
>
> There are several operations in MVCC flow which can be done under the page
> read lock instead of write lock. For example, setting xid_max on a datarow.
> It is safe, because races are possible only between concurrent transactions,
> which are not visible to each other.
> See {{MvccMarkUpdatedHandler}} and other similar handlers in this class.
