----------------------------------------

             Summary: Improve speed of checkpoint finalization on binary memory recovery
                 Key: IGNITE-10749
                 URL: https://issues.apache.org/jira/browse/IGNITE-10749
             Project: Ignite
          Issue Type: Improvement
          Components: cache
    Affects Versions: 2.0
            Reporter: Pavel Kovalenko
             Fix For: 2.8


Stopping node during checkpoint leads to binary memory recovery after node start.
When binary memory is restored node performs checkpoint that fixes the consistent state of the page memory.
It happens there

org.apache.ignite.internal.processors.cache.persistence.GridCacheDatabaseSharedManager#finalizeCheckpointOnRecovery
{noformat}

Looking at the implementation of this method we can notice that it performs finalization in 1 thread, which is not optimal. This process can be speed-up using parallelization of collecting checkpoint pages like in regular checkpoints.
