Subject [jira] [Updated] (PHOENIX-4333) Stats - Incorrect estimate when stats are updated on a tenant specific view
Date Tue, 31 Oct 2017 21:13:01 GMT

     [ https://issues.apache.org/jira/browse/PHOENIX-4333?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Samarth Jain updated PHOENIX-4333:
----------------------------------
    Attachment: PHOENIX-4333_test.patch

Test which demonstrates the issue that [~mujtabachohan] brought up. I would say it is working
fine. We call these estimates for a reason :). If the user desires more accuracy, he/she should
call UPDATE STATISTICS on the tenant view.

FYI, [~cody.marcel@gmail.com]

> Region 1 keys:
> A,1

> When stats are updated on tenant A view. Querying stats on tenant B view yield partial
results (only contains stats for B,1) which are incorrect even though it shows updated timestamp
as current.
