             Summary: Partition update counters and sizes may be different if 
cache is using readThrough
                 Key: IGNITE-7873
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.4
            Reporter: Pavel Kovalenko

Tracking partition update counters and cache sizes may not properly work if 
cache is using readThrough behavior.

Read requests to such cache can increment update counters or cache sizes not on 
all nodes serving such cache in case if data in underlying storage is changed.
It means that update counter or cache size will be incremented only on 
partition where we followed such request (primary or any random node).

BackupPostProcessingClosure should use preload=false for entry. In other case 
it can increment update counter for read request while data is not changed.
