Buckets are analogous to directories or folders in a traditional file system. +They serve as containers for keys (data objects). + +**Key Characteristics:** + +- **Contained within Volumes:** Every bucket must belong to a volume. +- **Container for Keys:** A bucket can contain any number of keys. +- **No Nested Buckets:** Unlike directories, buckets cannot contain other buckets. + +## Details + +### Creation and Management + +Buckets are created within a specified volume. + +```bash +ozone sh bucket create /myvolume/mybucket +``` + +For more details on bucket operations, refer to the [Ozone CLI documentation](../../../04-user-guide/01-client-interfaces/01-o3.md#bucket-operations). + +### Bucket Layouts (Object Store vs. File System Optimized) + +Ozone supports different bucket layouts, primarily: + +- **Object Store (OBS):** The traditional object storage layout, where keys are stored with their full path names. This is suitable for S3-like access patterns. +- **File System Optimized (FSO):** An optimized layout for Hadoop Compatible File System (HCFS) semantics, where intermediate directories are stored separately, improving performance for file system operations like listing and renaming. +For more details, refer to the [Prefix FSO documentation](../../../07-system-internals/07-features/01-filesystem-optimization.md). + +### Erasure Coding + +Erasure Coding (EC) can be enabled at the bucket level to define data redundancy strategies. This allows for more efficient storage compared to replication, especially for large datasets. +For more information, see the [Erasure Coding documentation](../../../07-system-internals/07-features/04-erasure-coding.md).
