Ivan Pavlukhin updated IGNITE-5935:
-----------------------------------
Description:
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.
was:
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.
