Chinmay Kulkarni commented on PHOENIX-5103:
-------------------------------------------
Okay there are 2 cases we can split the problem of orphan views into:
1. *4.14 client connecting to a 4.15 server (which has never gotten a
connection from a 4.15 client):*
- In this case, splitting of SYSCAT is not allowed yet, SYSTEM.TASK does not
exist and SYSTEM.CHILD_LINK does not exist.
- In this case, can we issue drop of child/grandchild... views synchronously as
per old 4.14 server logic before dropping the base table?
2. *4.14 client connecting to a 4.15 server (which has previously been
connected to by a 4.15 client):*
- In this case, SYSCAT may have split, SYSTEM.TASK and SYSTEM.CHILD_LINK exist.
- In this case, we can use the SYSTEM.TASK table to add tasks for
child-view-drops as per the current 4.15 server-side logic.
This will avoid orphan views for backward compatibility cases too. WDYT
