[jira] [Commented] (PHOENIX-2787) support IF EXISTS for ALTER TABLE
SET options
[ https://issues.apache.org/jira/browse/PHOENIX-2787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16765736#comment-16765736 ]
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?
> support IF EXISTS for ALTER TABLE SET options
