> It's desirable to be able to monitor how many read repair operations (background or blocking)
are performed, and how many of those detect mismatches. This allows configuring a low level
of background read repair, and detect if inconsistencies start to get out of bounds and alert
on those conditions. A follow-up patch will be provided.
