Subject [jira] [Commented] (CASSANDRA-9186) AbstractType vs. CQL3Type loses frozen keyword
Date Fri, 15 May 2015 16:22:59 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14545743#comment-14545743
] 

Tyler Hobbs commented on CASSANDRA-9186:
----------------------------------------

It would be okay to assume that tuples are always frozen, but we do have plans to support
non-frozen UDTs (e.g. CASSANDRA-7423), so we shouldn't always assume that they are frozen.

I think option 1 is the best choice, we just need to fix the Java driver.

> {code}
> Problem is that {{UserType}} and {{TupleType}} do not have a _frozen_ (or _isMultiCell_)
attribute. A conversion from type to cql3type therefore loses the _frozen_ status.
> EDIT: The issue has been discovered by [~aholmber]
