+# Processing multiple ref updates as a one event - pull-replication use case
+
+In this talk, we would like to discuss new stream event called `batch-ref-updated`
+which represents a single batch ref update operation.
+
+We will introduce the new stream event, discuss what are the benefits of using
+it and how to configure Gerrit to produce new events.
+After the introduction we would like to show a working example of the
+`batch-ref-update` event in pull-replication.
