[jira] [Created] (CASSANDRA-2812) Allow changing comparator between compatible collations

Allow changing comparator between compatible collations
-------------------------------------------------------

                 Key: CASSANDRA-2812
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2812
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 0.8.2


Normally we should not allow changing comparators, but anything that sorts in lexical byte order (Bytes, Ascii, UTF8, LexicalUUID) is compatible.

Linking to 2398, which uses the type information. Here or there (probably there?), we'll need to start recording type information with SSTables.

EDIT: Oops... resolved.

[jira] [Resolved] (CASSANDRA-2812) Allow changing comparator between compatible collations

Posted by "Jonathan Ellis (JIRA)" <ji...@apache.org>.

Jonathan Ellis resolved CASSANDRA-2812.
---------------------------------------

       Resolution: Won't Fix
    Fix Version/s:     (was: 0.8.2)
         Assignee:     (was: Jonathan Ellis)

Having written the patch, I think it's more confusion than it's worth to explain, "sometimes you can change comparator type but usually not."
