org.apache.cassandra.db.ArrayBackedSortedColumns
public class ArrayBackedSortedColumns
A ISortedColumns backed by an ArrayList. This implementation is not synchronized and should only be used when thread-safety is not required. This implementation makes sense when the main operations performed are iterating over the map and adding columns (especially if insertion is in sorted order).
