>                 URL: https://issues.apache.org/jira/browse/IGNITE-20685
>             Project: Ignite
>          Issue Type: Improvement
>            Reporter: Alexander Lapin
>            Priority: Major

> h3. Motivation
> Let's assume that the date node somehow found out that the transaction coordinator is dead, but the products of its activity such as locks and write intents are still present. In that case it’s necessary to check whether corresponding transaction was actually finished and if not finish it.
> h3. Definition of Done
>  * Transactions X that detects (detection logic will be covered in a separate ticket) that coordinator is dead awaits commitPartition primary replica and sends initiateRecoveryReplicaRequest to it in a fully asynchronous manner. Meaning that transaction X should behave itself in a way as it specified in deadlock prevention engine and do not explicitly wait for initiateRecovery result. Actually we do not expect any direct response from initiate recovery. Initiate recovery failover will be implemented in a different way.
> h3. Implementation Notes
> Given ticket is trivial and should be considered as a bridge between durable tx coordinator liveness detection and corresponding initiateRecoveryReplicaRequest handling. Both items will be covered in a separate tickets.
