Your other option is to create tables 'WITH COMPACT STORAGE'. Basically if you use COMPACT STORAGE and create tables as you did before.
https://issues.apache.org/jira/browse/CASSANDRA-2995 >From an application standpoint, if you can't do sparse, wide rows, you break compatibility with 90% of Cassandra applications. So that rules out almost everything; if you can't provide the same data model, you're creating fragmentation, not pluggability. I now call Cassandra compact storage 'c*' storage, and I call CQL3 storage 'c*++' storage. See debates on c vs C++ to understand why :).
