Subject [jira] [Commented] (CASSANDRA-4377) CQL3 column value validation bug
Date Tue, 10 Jul 2012 17:12:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13410554#comment-13410554
] 

paul cannon commented on CASSANDRA-4377:
----------------------------------------

bq. I would say explicitly throwing an exception when trying to access a cql3 column family
from thrift would be an acceptable solution.

-1 on that; it's very useful to have a lower-level access method to look at the "storage engine"
layer instead of the logical CQL3 rows at times.

> 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.
