Subject [jira] [Commented] (CASSANDRA-4377) CQL3 column value validation bug
Date Fri, 31 Aug 2012 15:27:07 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13446048#comment-13446048
] 

Nick Bailey commented on CASSANDRA-4377:
----------------------------------------

Just glanced at the patch, but it looks like this just makes cql3 cfs not show up in describe_keyspaces
calls right? Reading/writing to the cf would still go through and error?

If I'm looking at that right then it seems like we would want the opposite behavior. At least
from my perspective, I would like to have an indication that the cf exists in my client even
if i can't write to it.

> You can see in the above output that the stats cf is created with the column validator
set to text, but neither of the non primary key columns defined are text. It should either
be setting metadata for those columns or not setting a default validator or some combination
of the two.
