Subject [jira] [Created] (PHOENIX-6036) Introduce a new statement to rollback Splittable SYSTEM.CATALOG changes when phoenix.allow.system.catalog.rollback=true
Date Wed, 22 Jul 2020 21:50:00 GMT
Chinmay Kulkarni created PHOENIX-6036:
-----------------------------------------

             Summary: Introduce a new statement to rollback Splittable SYSTEM.CATALOG changes
when phoenix.allow.system.catalog.rollback=true
                 Key: PHOENIX-6036
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6036
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.15.0, 5.0.0
            Reporter: Chinmay Kulkarni
             Fix For: 5.1.0, 4.16.0


Setting phoenix.allow.system.catalog.rollback=true makes it possible for the user to rollback
changes introduced via Splittable SYSTEM.CATALOG. We however, do not have any command  to
do so and the operator is responsible for doing SYSTEM table surgeries via manual steps like
UPSERT SELECT statements to move parent->child links, running all drop view commands queued
in SYSTEM.TASK, etc. We should introduce a command to do this for the user automatically.
