Summary: Possible tx desync during recovery on near node left.
Key: IGNITE-12548
URL: https://issues.apache.org/jira/browse/IGNITE-12548
Project: Ignite
Issue Type: Bug
Affects Versions: 2.7.6
Reporter: Alexey Scherbakov
Assignee: Alexey Scherbakov
Fix For: 2.9
The problem appears if a transaction is starting to rollback in PREPARED state
for some reason and concurrently near node is left triggering tx recovery
protocol.
Consider having two enlisted keys from different partitions mapped to different
nodes N1 and N2.
Due to race N1 local tx can be rolled back while N2 local tx is committed
breaking tx atomicity guarantee.
