+Writer side filtering on late joiners |Pro|
+-------------------------------------------
+
+By default, when a late joiner DataReader is discovered (non-volatile durability scenario), the DataWriter will not
+apply the filter for that DataReader on historical samples.
+This means that the late joiner DataReader will receive all historical samples, even those that would not match its
+filter, which could cause performance degradation on resource-limited systems.
+
+It is possible however to configure a DataWriter to perform writer-side filtering on late joiners by setting the
+|DataWriterQos| property ``fastdds.content_filtering_on_late_joiners`` to ``true``.
