Subject [jira] [Created] (PHOENIX-5456) IndexScrutinyTool slow for indexes on multitenant tables
Date Tue, 27 Aug 2019 23:52:00 GMT
Vincent Poon created PHOENIX-5456:
-------------------------------------

             Summary: IndexScrutinyTool slow for indexes on multitenant tables
                 Key: PHOENIX-5456
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5456
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.15.0, 5.1.0
            Reporter: Vincent Poon


The IndexScrutinyTool is doing full scans for index tables on multitenant tables. 
This is due to a change in PHOENIX-5089, where we added code to IndexColumnNames to skip a
portion of the PK if the table is multitenant:

https://github.com/apache/phoenix/commit/cc9754fff840f38d13c3adb0c963296959fff3fa#diff-0705645faa779229d00792c032ed377fR64

This causes scrutinies for global, non-view indexes on multitenant tables to skip the tenantId
when generating the pk column list, thereby causing a full scan.
