Re: [paho-dev] Offline Buffering in C client

I don't remember setting a maximum for the maximum! What I would say, is that this is not a good place to store a large amount of data. It's a temporary resting place.

Hi Ian,


Is there any maximum limit for maxBufferedMessages parameter or it depends on the memory (INT_MAX in other words)?

Hi Said,

it is implemented. There is a setting for the maximum number of buffered messages:

https://www.eclipse.org/paho/files/mqttdoc/MQTTAsync/html/struct_m_q_t_t_async__create_options.html#a3b74acf6f315bb5fe36266bc9647ee97

Also, by checking the callback responses to publish, the application can keep track of how many messages are still outstanding, when the QoS > 0. (QoS 0 messages have no responses so there is less feedback).

Hi Everybody,

I just want to be sure that C client has offline sending feature (in Async client)? I saw comment that says " *ÂÂÂ Ian Craggs - automatic reconnect and offline buffering (send while disconnected) " on MQTTAsync.h, however I'm not sure if it is implemented or feature enhancement. If offline buffering implemented, are there any configuration available to use in application (Setting the max number of messages that will be stored offline etc.)?

Best Regards,
Said U.
