------------------------------------------
Summary: Proper handling of a rebalancing with disabled WAL
Key: IGNITE-13171
URL: https://issues.apache.org/jira/browse/IGNITE-13171
Project: Ignite
Issue Type: Bug
Affects Versions: 2.8
Reporter: Alexey Scherbakov
Assignee: Alexey Scherbakov
Fix For: 2.9
Current implementation of a optimized rebalancing with disabled WAL used when
all local partitions are MOVING and persistence is enabled has multiple flaws:
# There are races between concurrent topology change and partition owning
after a checkpoint causing consistency issues.
# Partitions will not be owned after a topology has changed and new topology
version is compatible with previous.
This is the reason for flaky tests [1] [2]
