> The GlobalIndexChecker coprocessor is responsible for checking if an index 
> row is "verified", that is, has completed its most recent two-phase write 
> operation, during scans.  If the row is not verified then the coprocessor 
> rebuilds the row using a read-repair technique. The read-repair operations 
> should be rare but add extra latency on the scan operations. We need to know 
> how many read-repair operations happen and how long they take. Thus, we need 
> metrics on them.
