> 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.
