[jira] [Commented] (CASSANDRA-17509) Add Guardrail to disable GROUP BY functionality

    [ https://issues.apache.org/jira/browse/CASSANDRA-17509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17518480#comment-17518480 ] 

David Capwell commented on CASSANDRA-17509:
-------------------------------------------

Patch LGTM, I left small comments mostly about "is" vs "get" in MBeans/Interfaces... I see that we use "get" already, but this is actually incorrect... so think we should also fix (100% cool not in this patch, I accept consistency here over correctness)

> GROUP BY can be expensive and troublesome on large tables. We should have a guardrail to disable this in clusters where we don't want users to have this functionality.
