      Description

      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.
