Subject: [OASIS Issue Tracker] (MQTT-252) Support for large message transmission
[ https://issues.oasis-open.org/browse/MQTT-252?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Richard Coppen updated MQTT-252: -------------------------------- Priority: Critical (was: Major) > Support for large message transmission > -------------------------------------- > > Key: MQTT-252 > URL: https://issues.oasis-open.org/browse/MQTT-252 > Project: OASIS Message Queuing Telemetry Transport (MQTT) TC > Issue Type: New Feature > Components: futures > Affects Versions: 3.1.1 > Reporter: Andrew Schofield > Priority: Critical > > MQTT has an architected limit of 256MB for the message payload. In practice, transmitting a message this large is troublesome. First, the transmission of large messages ties up the network connection for a considerable time, potentially blocking smaller messages. Second, the longer a message takes to transmit, the higher the chance that a network outage will interrupt the transmission, which would then have to be restarted from the beginning. MQTT would make a good transport for delivery of large payloads, in particular device firmware, but only if they can be transmitted in a more manageable way. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
