Examples of SuperColumn

org.apache.cassandra.db.SuperColumn
org.apache.cassandra.thrift.SuperColumn
A named list of columns. @param name. see Column.name. @param columns. A collection of standard Columns. The columns within a super column are defined in an adhoc manner.Columns within a super column do not have to have matching structures (similarly named child columns).
