Re: [paho-dev] controing generated persistent messages

[Frank Pagliughi <fpagliughi@xxxxxxxxxxxxxx>]

    You don't mention which of the man Paho libraries that you're using,
    but it sounds like the C lib?
    
    Either way, I don't believe that any of the libraries will do this
    for you directly how you want. But just about all of them give you
    the ability to write this yourself pretty easily. 
    
    The thing about most MQTT client libraries is that they are very
    connection aware. You are normally alerted when the connection with
    the broker is lost, and if set for automatic reconnects, you can be
    alerted again when the connection is re-established.
    
    So, when the connection is lost, rather than trying to publish
    messages, just put them into a local, application queue. Then, when
    the connection is re-established, send them at the rate that you
    desire.

Hi,

I want to control the number of messages sent per second when the persistence type is set to MQTTCLIENT_PERSISTENCE_DEFAULT.

So, for example consider that  the internet is disconnected/down for 1 hour and in this 1 hour 100 messages are generated. When the connectivity is back then I see that all 100 messages are sent in burst.

I want to limit this to say 10 messages per second? Is there a way to achieve this? Will setting "maxInflight" help solve the problem?

Thanks !
