+
+        Aerospike has no explicit schema, and records/sets are created lazily
+        on first write, so there is nothing to do for ``tables_to_keep`` or
+        either of the entity lists. For ``tables_to_delete`` we strip each
+        feature-view's slot out of the ``features`` and ``event_ts`` Map
+        CDTs on every record in the project's set.
+
+        This is issued as a single **background scan** with a combined op
+        list covering all feature views being removed, so the cost is a
+        single server-side pass regardless of how many feature views are
+        dropped. The scan runs asynchronously server-side and returns
+        immediately; this matches the intent of ``feast apply``, after
+        which the caller stops reading the dropped feature views anyway.
