So what happens when you create the follower but not followed index then realize you need it. Is there a way to create that new ColumnFamily without writing a object-by-object program that must traverse all the data? I suppose the concept of data locality doesn't apply, but what is the best way to do that sort of operation?

You'd write a MapReduce program to do it. Cassandra 0.6 has full support for Hadoop.
