Examples of org.apache.cassandra.db.ArrayBackedSortedColumns

org.apache.cassandra.db.ArrayBackedSortedColumns
A ColumnFamily backed by an array. 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 cells and adding cells (especially if insertion is in sorted order).
