| Google's <a href="http://research.google.com/archive/gfs.html">GFS</a>.</p> |
| |
| <p>The most important difference is that unlike GFS, Hadoop DFS files |
| have strictly one writer at any one time. Bytes are always appended |
| to the end of the writer's stream. There is no notion of "record appends" |
| or "mutations" that are then checked or reordered. Writers simply emit |
| a byte stream. That byte stream is guaranteed to be stored in the |
| order written.</p></div> |
