Todd Nine edited comment on CASSANDRA-2231 at 3/2/11 8:42 PM: -------------------------------------------------------------- Enforcing all columns to be the same would break our indexing. Each row key is a different index, and the columns within that index are composed of different composite types. If this was enforced at the CF level, we would require a different CF for each index. Is it possible to allow both static and dynamic types by creating 2 composite index types?

One scenario for the usage of these is documented here: > http://www.anuff.com/2010/07/secondary-indexes-in-cassandra.html.
