[jira] [Created] (PHOENIX-5527) Unverified index rows should not be
deleted due to replication lag
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.
