Subject: [OASIS Issue Tracker] (MQTT-427) Message ordering for shared subscriptions
Jonathan Levell created MQTT-427: ------------------------------------ Summary: Message ordering for shared subscriptions Key: MQTT-427 URL: https://issues.oasis-open.org/browse/MQTT-427 Project: OASIS Message Queuing Telemetry Transport (MQTT) TC Issue Type: Bug Affects Versions: 5 Reporter: Jonathan Levell At the moment, the spec makes no exception for ordering for shared subscriptions. I think the TC has agreed that the ordering requirements do not apply to shared subscriptions but that is not reflected in WD11 as far as I can see. (For one example of non-ordering, consider a shared subscription with two clients receiving messages as QoS=1. Client A receives message 1 (but does not ack it). Client B receives messages 2 & 3 and acks them. Client A's session then expires. I think we want servers to be able to deliver message 1 to Client B). -- This message was sent by Atlassian JIRA (v6.2.2#6258)
