Subject [jira] [Updated] (PHOENIX-5138) ViewIndexId sequences created after PHOENIX-5132 shouldn't collide with ones created before it
Date Wed, 13 Feb 2019 18:07:00 GMT

     [ https://issues.apache.org/jira/browse/PHOENIX-5138?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Geoffrey Jacoby updated PHOENIX-5138:
-------------------------------------
    Description: 
PHOENIX-5132 changed the ViewIndexId generation logic to use one sequence per physical view
index table, whereas before it had been tenant + physical table. This removed the possibility
of a tenant view index and a global view index having colliding ViewIndexIds.

However, existing Phoenix environments may have already created tenant-owned view index ids
using the old sequence, and under PHOENIX-5132 if they create another, its ViewIndexId will
got back to MIN_VALUE, which could cause a collision with an existing view index id.
