MQTT 5 Essentials Part 11 – Flow Control

Lovely! This is good when we have millions of vehicles sending 10 messages per seconds with QoS 1 and server is overwhelmed with these messages to ack back. If client can set "Receive Maximum" as 100, server can just send one ACK per 10 sec to each client and will hugely reduce load on servers.

Very informative, I would say. Thanks for sharing this content, Florian.
