[jira] [Created] (PHOENIX-5519) Metric for global read repairs due to concurrent updates

Lars Hofhansl created PHOENIX-5519:
--------------------------------------

             Summary: Metric for global read repairs due to concurrent updates
                 Key: PHOENIX-5519
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5519
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Lars Hofhansl


The global indexer cannot distinguish between (1) a prior update that failed to complete and (2) an ongoing update that hasn't finished, yet.

In order to distinguish these cases the code uses a heuristic by assuming that no update will take longer the N timeunits to finish. N defaults to 10 minutes.

We should have an additional, separate metric for this case.

[~priyankporwal], FYI.
