| <p><em><em>Ozone is a scalable, redundant, and distributed object store for Hadoop. <p> |
| Apart from scaling to billions of objects of varying sizes, |
| Ozone can function effectively in containerized environments |
| like Kubernetes.</em></em> <p></p> |
| |
| <p>Applications like Apache Spark, Hive and YARN, work without any modifications when using Ozone. Ozone comes with a <a href="./interface/javaapi.html">Java client library</a>, <a href="./interface/s3.html">S3 protocol support</a>, and a <a href="./shell.html">command line interface</a> which makes it easy to use Ozone.</p> |
| |
| <p>Ozone consists of volumes, buckets, and keys:</p> |
| |
| <ul> |
| <li>Volumes are similar to user accounts. Only administrators can create or delete volumes.</li> |
| <li>Buckets are similar to directories. A bucket can contain any number of keys, but buckets cannot contain other buckets.</li> |
| <li>Keys are similar to files.</li> |
| </ul> |
