             Summary: Partition update counters and sizes may be different if cache is using
readThrough
                 Key: IGNITE-7873
                 URL: https://issues.apache.org/jira/browse/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.
