> MVCC TX: Tx recovery protocol
> -----------------------------
>
> Key: IGNITE-5935
> URL: https://issues.apache.org/jira/browse/IGNITE-5935
> Project: Ignite
> Issue Type: Task
> Components: cache, mvcc
> Reporter: Semen Boikov
> Assignee: Ivan Pavlukhin
> Priority: Major
> Fix For: 2.7
>
>
> Transaction recovery procedure is initiated when near node failed before
> transaction was finished.
> In MVCC transactions _partition update counter_ modification is started on
> prepare phase. If a transaction was prepared at least on one node we need to
> finish _partition update counter_ modification consistently on all
> participating nodes.
> Also recovered transaction should be removed from active transactions list on
> mvcc coordinator.
