Igor Seliverstov updated IGNITE-5935:
-------------------------------------
Description:
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.
was:
Need make sure tx recovery work properly with mvcc enabled:
- tx IDs are generated and not lost if transaction is committed by recovery
procedure
- tx should be removed from list of active transactions on coordinator
