Ranger metadata

When a DLM replication job is run, data, metadata, and any Ranger policies that are associated with the replicated data are automatically exported to the target.

The replicated data on the destination is marked as read-only by adding a deny policy on the replicated data in Ranger in the destination cluster. This prevents accidental writes on the copy.

For on-premise to on-premise replications, the policies, permissions, and ACLs are retained and applied to the data on the target, except that the destination data is read-only.

For on-premise to cloud replication, the Ranger policies, permissions, and ACLs are stored in metadata files in cloud storage. Data in the cloud is protected using security features in the cloud environment.
