-------------------------------------
Similar but looks abandoned
> Cross DC feature for Ozone
> --------------------------
>
> Key: HDDS-11988
> URL: https://issues.apache.org/jira/browse/HDDS-11988
> Project: Apache Ozone
> Issue Type: New Feature
> Reporter: Semyon Orlov
> Assignee: Semyon Orlov
> Priority: Major
>
> *Problem:*
> High traffic costs and slow computations when reading data from Ozone, as
> data consumers and compute resources are located in different data centers.
> *Goal:*
> Enable data replication between data centers, optimizing efficiency based on
> data consumption and storage strategies.
> *Description:*
> *Scenario 1*
> _Folder 1_ - Replication factor: 6, with 2 copies in each data center.
> Shared data needed by all consumers across all data centers.
> Replication factor exceeds 3 to avoid inter-data-center traffic in case of a
> single copy failure.
> *Scenario 2*
> _Folder 2_ - Erasure coding within Data Center 1.
> Data is only required by consumers in Data Center 1.
> *Scenario 3*
> _Folder 3_ - Erasure coding within Data Center 3.
> Data stored as cold data on slow HDDs.
