> Key: IGNITE-21762
> URL: https://issues.apache.org/jira/browse/IGNITE-21762
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexander Lapin
> Assignee: Kirill Sizov
> Priority: Major
> Labels: ignite-3
>
> h3. Motivation
> As mentioned in IGNITE-21761 it's valid to remove finished transaction when
> cleanup is fully replicated over all enlisted partitions. However it's
> possible that commitPartition that triggers cleanup after txnState update
> will drop right after a state update but before sending a cleanup request, or
> it'll be killed during cleanup result processing, or commit partition primary
> replica will be re-elected, so many bad options...
> All in all that means, that in order to mark persistent txnState as ready for
> removal it's required to re-send cleanup request on commit partition primary
> replica election even if it was previously finished.
> h3. Definition of Done
> * Populate txn persistent state with enlisted partitions on txnState update.
> It's required in order to determine the list of nodes to which the cleanup
> request will need to be sent.
> * In an asynchronous manner on commit partition primary replica election,
> scan local persistent txn state storage and send cleanup request in a durable
> manner. We should not use the thread of primary replica election notification
> for that.
> * On cleanup completion, meaning cleanup replication over majorities of all
> enlisted partitions txnStateVolatileMap will be populated with stamped
> txnState because of logic introduced in IGNITE-21761
