----------------------------------------
Hi [~ivan.glukos], thank you for reviewing changes!
I've updated PR. magic no fixed, test IgniteCheckpointDirtyPagesForLowLoadTest
was created.
It fails in case too much pages marker dirty
> Avoid updating PagePartitionCounters in case all counters were not modified

> Priority: Critical

> PagePartitionCountersIO ignores actual values of counters and marks pages
> dirty even if partition has no counters update.
> This leads to PAGE_RECORD creation for pages from PagePartitionCountersIO
> and as result with pages from TrackingPageIO.
> These modificaiton may be skipped if counters are checked for equality before
> storing data.
