Andrew Schofield created MQTT-252: ------------------------------------- Summary: 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: core Affects Versions: 3.1.1 Reporter: Andrew Schofield 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)
