Hi, Sometimes, when trying to send a message to a broker it cannot be send correctly due to high disk usage on broker's machine, so message is lost.
To face it I thought 2 different options: 1) Use sync parameter in send() call to wait for broker confirmation 2) To, asynchronously, take control of messages that have not been confirmed and try to resend them. As option 1 entail to process get blocked until broker confirm the reception of the message, my choice is option 2. However, I don't know how get the list of messages whose reception was not confirmed by broker. Analyzing class Sender I find the method getUnsettled() that return the number of unsettled messages, but nothing that return the list of messages. Also, I have read that if connection fails, after reconnect, the unsettled messages will be retransmitted, so I suspect that the retrieve of unsettled messages could be possible. So, in conclussion, my questions are: Is possible to get the list of unsettled messages? If possible, how I can get it? Thank you in advance.
