Is MQTT capable of saving messages to database
|Added at||2016-12-26 15:12|
From my research MQTT brokers only save the most recent message but facebook uses MQTT in its messenger app. So are they using a custom broker to retain the messages?
My question is it possible for mqtt brokers to retain all messages sent so that I can create my own chat messaging mobile application? I know that paid services like HiveMQ offer this functionality but I am looking for a free alternative.
