@Inject
public ReadRange(CqlSession session,
                 @BinaryReadConsistency
                 ConsistencyLevel consistency)
```
    Parameters:
    
    session - the cassandra session
    
    consistency - the consistency level

  - execute
```
public CompletionStage<InputStream> execute(IRI id,
                                            int first,
                                            int last)
```
    Parameters:
    
    id - the IRI of a binary to read
    
    first - which byte to begin reading on
    
    last - which byte to end reading on
    
    Returns:
    
    An InputStream of bytes as requested. The skip method of this InputStream is guaranteed to skip as many bytes as asked.
