> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Devesh Kumar Singh
> Assignee: Devesh Kumar Singh
> Priority: Major
> Labels: pull-request-available
>
> Adds storagePolicy and allowFallbackStoragePolicy as new optional fields on
> Ozone buckets, alongside the existing storageType. This enables a bucket to
> declare which OzoneStoragePolicy (HOT/WARM/COLD) its blocks should use, and
> whether block allocation is allowed to fall back to the policy's secondary
> tier when the primary tier has no capacity.
>

>
> The existing per-bucket StorageType attribute is a coarse-grained concept.
> StoragePolicy provides a richer model: it bundles a creation tier (e.g. SSD
> for HOT) with a fallback tier (e.g. DISK), allowing intelligent data
> placement and graceful degradation when a preferred storage tier is full.
> This change lays the data-model foundation for subsequent patches that thread
> StoragePolicy through
> key creation and block allocation.
