+Max Affected
+============
+
+You can set a limit to the amount of resources affected in a request by sending ``max-affected`` preference. This feature works in combination with ``handling=strict`` preference. ``max-affected`` would be ignored with lenient handling. The "affected resources" are the number of rows returned by ``DELETE`` and ``PATCH`` requests. This is also supported through ``RPC`` calls.
+
+To illustrate the use of this preference, consider the following scenario where the ``items`` table contains 14 rows.
+
+.. tabs::
+
+  .. code-tab:: http
+
+    DELETE /items?id=lt.15 HTTP/1.1
+    Content-Type: application/json; charset=utf-8
