Enumerator
PTDiffusionTopicUnsubscriptionReason_Requested	Unsubscribed by the subscribing client. Since 5.6
PTDiffusionTopicUnsubscriptionReason_Control	The unsubscription was requested either by another client or by the server. Since 5.6
PTDiffusionTopicUnsubscriptionReason_Removal	The unsubscription occurred because the topic was removed. Since 5.6
PTDiffusionTopicUnsubscriptionReason_Authorization	The unsubscription occurred because the session is no longer authorized to access the topic. Since 5.9
PTDiffusionTopicUnsubscriptionReason_Unknown	A reason that is unsupported by the session. Since 6.1
PTDiffusionTopicUnsubscriptionReason_BackPressure	The server has a significant backlog of messages f`or the session, and the topic specification has the conflation topic property set to "unsubscribe". The session can resubscribe to the topic. The unsubscription is not persisted to the cluster. If the session fails over to a different server it will be resubscribed to the topic.
PTDiffusionTopicUnsubscriptionReason_BranchMappings	The unsubscription occurred because branch mapping rules changed. Since 6.7 See Also PTDiffusionSessionTrees
PTDiffusionTopicUnsubscriptionReason_SubscriptionRefresh	The server has re-subscribed this session to the topic. Existing streams are unsubscribed because the topic type and other attributes may have changed. This can happen if a set of servers is configured to use session replication, and a session connected to one server reconnects ("fails over") to a different server. Since 5.9
PTDiffusionTopicUnsubscriptionReason_StreamChange	A fallback stream has been unsubscribed due to the addition of a stream that selects the topic. Since 5.9
