Subject [jira] [Commented] (CASSANDRA-13959) Add yaml flag for disabling MVs, log warnings on creation
Date Tue, 17 Oct 2017 14:26:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16207702#comment-16207702
] 

Aleksey Yeschenko commented on CASSANDRA-13959:
-----------------------------------------------

Had a quick conversation about this with [~slebresne]. He raised a point that logging a warning
every time we load an MV is unreasonable - and I agree that it is. Can we only keep the warning
on creation?

Could add a small dtest (or utest if you so prefer) to show that:
1. Setting the flag to {{false}} really disables creation, and
2. That a client warning is emitted

Aside from this, looks good to me. Maybe give it a week before committing (till next Tue/Wed),
to let people with binding -1s have a chance to change their mind since dev@ discussion though.

creation, and log warnings when they're created.
