[jira] [Created] (IGNITE-8610) Searching checkpoint / WAL history for rebalancing is not properly working in case of local/global WAL disabling

Pavel Kovalenko created IGNITE-8610:
---------------------------------------

             Summary: Searching checkpoint / WAL history for rebalancing is not properly working in case of local/global WAL disabling
                 Key: IGNITE-8610
                 URL: https://issues.apache.org/jira/browse/IGNITE-8610
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.5
            Reporter: Pavel Kovalenko
            Assignee: Pavel Kovalenko
             Fix For: 2.6


After implementation IGNITE-6411 and IGNITE-8087 we can face with situation when after some checkpoint, WAL was temporarily disabled and enabled again. In this case we can't treat such checkpoint as start point to rebalance, because WAL history after such checkpoint may contain gaps.

We should rework our checkpoint / wal history searching mechanism and ignore such checkpoints.
