-.. tip::
+As an alternative to capped collections, consider :ref:`TTL (Time To
+Live) indexes <index-feature-ttl>`. TTL indexes allow you to expire and
+remove data from normal collections based on the value of a date-typed
+field and a TTL value for the index. You can also use a TTL index on a
+capped collection to remove expired documents even if the capped
+collection hasn't exceeded its size limit. For details, :ref:`ttl-collections`.
