+Notification Reliability
+------------------------
+
+Notifications may be sent synchronously, as part of the operation that triggered them. 
+In this mode, the operation is acked only after the notification is sent to the topic's configured endpoint, which means that the
+round trip time of the notification is added to the latency of the operation itself.
+
+.. note:: The original triggering operation will still be considered as sucessful even if the notification fail with an error, cannot be deliverd or times out
+
+Notifications may also be sent asynchronously. They will be committed into persistent storage and then asynchronously sent to the topic's configured endpoint.
+In this case, the only latency added to the original operation is of committing the notification to persistent storage.
+
+.. note:: If the notification fail with an error, cannot be deliverd or times out, it will be retried until successfully acked
+
+.. tip:: To minimize the added latency in case of asynchronous notifications, it is recommended to place the "log" pool on fast media
