+When all messages for a given key are deleted, the topic partition keeps one message, called a tombstone, that contains the key, and a null value. A tombstone indicates to clients that the messages have been deleted. You can specify how long Redpanda keeps these tombstones using both a cluster configuration property `tombstone_retention_ms` and a topic configuration property `delete.retention.ms`. If both are set, the topic-level tombstone retention policy overrides the cluster-level policy.
 
-* For topics with a `compact,delete` policy, Redpanda deletes the tombstones when a topic reaches its retention limits.
-* For topics with a `compact` policy, Redpanda deletes the tombstones based on the specified tombstone retention policy. This retention policy is set with the `delete.retention.ms` topic configuration property. 
+[NOTE]
+====
+You cannot enable `tombstone_retention_ms` if you have enabled any of the Tiered Storage cluster properties `cloud_storage_enabled`, `cloud_storage_enable_remote_read`, and `cloud_storage_enable_remote_write`.
+
+On the topic level, you cannot enable `delete.retention.ms` at the same time as the Tiered Storage topic configuration properties `redpanda.remote.read` and `redpanda.remote.write`.
+====
+
+To set the cluster-level tombstone retention policy, run the command:
+
+[,bash]
+----
+rpk cluster config set tombstone_retention_ms=100
+----
+
+You can set the tombstone retention for a topic so that it inherits the cluster-wide default:
+
+[,bash]
+----
+rpk topic alter-config <topic-name> --delete delete.retention.ms
+----
+
+To override the cluster-wide default for a specific topic:
+
+[,bash]
+----
+rpk topic alter-config <topic-name> --set delete.retention.ms=5
+----
+
+To disable tombstone retention for a specific topic:
+
+[,bash]
+----
+rpk topic alter-config <topic-name> --set delete.retention.ms=-1
