org.apache.cassandra.thrift.KeySlice
A KeySlice is key followed by the data it maps to. A collection of KeySlice is returned by the get_range_slice operation. @param key. a row key @param columns. List of data represented by the key. Typically, the list is pared down to only the columns specified bya SlicePredicate.
