> Key: IGNITE-5935
> URL: https://issues.apache.org/jira/browse/IGNITE-5935
> Project: Ignite
> Issue Type: Task
> Components: cache, mvcc
> Reporter: Semen Boikov
> Priority: Major
> Fix For: 2.7
>
>
> Tx recovery doesn't work properly for txs over MVCC enabled caches using
> Cache API. It requires MvccSnapshot which may not be acquired at recovery
> time.
> Need to implement logic for checking whether snapshot was already gotten by
> one of tx participants and use existing one, request and spread between
> participants a new snapshot otherwise.
