Which term describes a marker that relays to servers to delete copies of data that has been deleted locally?

Explanation:
In distributed data stores, a delete operation creates a tombstone—a marker that indicates the item has been deleted. This tombstone is propagated to all other servers so they also delete the corresponding data and don’t reappear during replication or compaction. The tombstone ensures the deletion is consistently applied across the cluster, even if some nodes were offline when the delete happened. Over time, tombstones are cleaned up once they’re no longer needed. Other terms describe different ideas: a token maps data to nodes via hashing, topology refers to how nodes are arranged and connected, and a top-level domain is a DNS concept.
