--------------------------------------
Summary: Metrics for the GlobalIndexChecker coprocessor
Key: PHOENIX-5358
URL: https://issues.apache.org/jira/browse/PHOENIX-5358
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.14.2, 5.0.0, 4.13.1, 4.15.0
Reporter: Kadir OZDEMIR
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 to
metrics on them.
