Apache Ozone - Next-Gen Storage

Apache Ozone is a scalable, redundant, and distributed object store optimized for big data workloads. Apart from scaling to billions of objects of varying sizes, applications that use frameworks like Apache Spark, Apache YARN and Apache Hive work natively on Ozone without any modifications. Ozone natively supports the S3 API and provides a Hadoop-compatible file system interface. Ozone is typically available in a CDP Private Cloud Base deployment.

Ozone consists of three important storage elements: volumes, buckets, and keys. Each key is part of a bucket, which, in turn, belongs to a volume. Only an administrator can create volumes. Depending on their requirements, regular users can create buckets in volumes. Ozone stores data as keys inside these buckets.

When a client writes a key, Ozone stores the associated data on DataNodes in chunks called blocks. Therefore, each key is associated with one or more blocks. Within a DataNode, multiple unrelated blocks can reside in a storage container.

To understand the concepts of Ozone, you can refer to the Ozone overview and introduction documentation.
