enum PTDiffusionTopicUnsubscriptionReason

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
