Subject [jira] [Commented] (PHOENIX-2787) support IF EXISTS for ALTER TABLE SET options
Date Tue, 12 Feb 2019 06:49:00 GMT

Xinyi Yan commented on PHOENIX-2787:
------------------------------------

[~vincentpoon] if nobody is working on this, I want to do it.

but I do have some questions here:
 # If a table already has options, do we allow this change? 
 # are we going to support all options that lists here [https://phoenix.apache.org/language/index.html#options]
 # whats the most valuable use case here?
