Alexey Goncharuk commented on IGNITE-8393:
------------------------------------------
[~ivan.glukos], in the test you are trying to start two checkpoints, however
the second checkpoint will be skipped (or may be skipped) because there are no
modified pages after the first checkpoint. Please double-check the behavior.

> We should softly handle this situation: print message in log and continue the
> compression with next segment.
> We also should handle "skipped" segments and don't delete them in
> deleteObsoleteRawSegments().
