[jira] [Created] (IGNITE-11455) Introduce free lists rebuild mechanism

Pavel Kovalenko created IGNITE-11455:
----------------------------------------

             Summary: Introduce free lists rebuild mechanism
                 Key: IGNITE-11455
                 URL: https://issues.apache.org/jira/browse/IGNITE-11455
             Project: Ignite
          Issue Type: Improvement
          Components: cache
    Affects Versions: 2.0
            Reporter: Pavel Kovalenko
             Fix For: 2.8


Sometimes the state of free lists become invalid like in https://issues.apache.org/jira/browse/IGNITE-10669 . It leads the node to an unrecoverable state. At the same time, free lists don't hold any critical or data information and can be built from scratch using existing data pages. It may be useful to introduce a mechanism to rebuild free lists using an optimal algorithm of partition data pages scanning.
