[jira] [Created] (IGNITE-9185) Collect and check update counters visited during WAL rebalance

Pavel Kovalenko created IGNITE-9185:
---------------------------------------

             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.
