Jonathan Ellis commented on CASSANDRA-1714:
-------------------------------------------
that's one approach (when the method knows how to take a ByteBuffer object),
the other is replacing with get(i) like I did for the compareUnsigned
> zero-copy reads

> Since we are already using mmap'd ByteBuffers in MappedFileDataInput we
> should be able to do zero-copy reads (via buffer.slice()), which would give
> us better performance than CASSANDRA-1651 without having to worry about
> buffer management.
