Subject: [OASIS Issue Tracker] (MQTT-276) MQTT enhancements for large scale distributed systems
[ https://issues.oasis-open.org/browse/MQTT-276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=61688#comment-61688 ] Ian Craggs commented on MQTT-276: --------------------------------- I think that the list of optional features is: * QoS 2 * retained publications * cleansession false and that maximum message size belongs into a separate category of "constraints". "Constraints" or limits, could also include maximum number of outstanding QoS 2 messages. I also think that advertising server capabilities is fine, but we do not want to have capability negotiation, which would add too much complexity. > MQTT enhancements for large scale distributed systems > ----------------------------------------------------- > > Key: MQTT-276 > URL: https://issues.oasis-open.org/browse/MQTT-276 > Project: OASIS Message Queuing Telemetry Transport (MQTT) TC > Issue Type: New Feature > Components: futures > Affects Versions: 3.1.1 > Reporter: Konstantin Dotchkoff > Assignee: Konstantin Dotchkoff > Fix For: 3.1.1 > > > As presented during the TC call on 8/6/2015, there are challenges in implementing MQTT in large scale distributed systems with the specific case being QoS 2: > https://www.oasis-open.org/apps/org/workgroup/mqtt/download.php/56237/MQTT%20QoS2%20Considerations.pptx > Retained messages were also noted during the call. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
