org.apache.cassandra.thrift.Mutation
A Mutation is either an insert (represented by filling column_or_supercolumn) or a deletion (represented by filling the deletion attribute). @param column_or_supercolumn. An insert to a column or supercolumn (possibly counter column or supercolumn) @param deletion. A deletion of a column or supercolumn
