---------------------------------------
Summary: Collect and check update counters visited during WAL
rebalance
Key: IGNITE-9185
URL: https://issues.apache.org/jira/browse/IGNITE-9185
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 2.5
Reporter: Pavel Kovalenko
Assignee: Pavel Kovalenko
Fix For: 2.7
Currently we don't check what update counters we visit during WAL iteration and
what data we send to a demander node. There can be situation, that we met last
requested update counter in WAL and stop rebalance process, while due to
possible DataRecord's reordering we miss some updates after.
If rebalance process breaks due to end of WAL, but not all data records were
visit, we can easily check what records are missed, cancel rebalance and print
useful information to log for further debug.
