---------------------------------------
Summary: WAL disabling during rebalance mechanism uses wrong
topology version in case of exchanges merge
Key: IGNITE-8544
URL: https://issues.apache.org/jira/browse/IGNITE-8544
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 2.5
Reporter: Pavel Kovalenko
Assignee: Pavel Kovalenko
Fix For: 2.6
After exchange is done, we're using initial exchange version to determine
topology version on what rebalance should be finished and save it. After
rebalance finishing we check current topology version and saved version and if
they are equal, we enable WAL, own partitions and do checkpoint. In other case
we do nothing, because of topology change.
In case of exchanges merge we're saving old topology version (before merge) and
it leads to ignoring logic of enabling WAL and etc, because check on topology
version will be always false-positive.
