Subject Changing comparator
Date Fri, 03 Aug 2012 08:56:10 GMT

I know that changing a CF's comparator is not officially supported. 
However, there is a post by Jonathan Ellis that implies it can be done 

I assume that we'd have to change entries in the system.schema_* column 

Has anyone successfully done this?

We want to change the comparator from BytesType to UTF8Type to make the 
move to CQL easier ("cannot parse 'foo' as hex bytes"). Our CFs were 
created back in the Cassandra 0.6.x days and are too large to be easily 
copied to new CFs with a new schema.

Many thanks in advance.
