Subject [jira] [Created] (PHOENIX-5527) Unverified index rows should not be deleted due to replication lag
Date Mon, 14 Oct 2019 16:45:00 GMT
Kadir OZDEMIR created PHOENIX-5527:
--------------------------------------

             Summary: Unverified index rows should not be deleted due to replication lag 
                 Key: PHOENIX-5527
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5527
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.14.3, 5.0.0
            Reporter: Kadir OZDEMIR
            Assignee: Kadir OZDEMIR


The current default delete time for unverified index rows is 10 minutes. If an index table
row is replicated before its data table row and the replication row is unverified at the time
of replication, it can be deleted when it is scanned on the destination cluster. To prevent
these deletes due to replication lag issues, we should increase the default time to 7 days.
This value is configurable using the configuration parameter,  phoenix.global.index.row.age.threshold.to.delete.ms.
