   Try to present a solution, the problem is that in the resend logic after the reconnection of producer, no mater the item in pendingQueue has been sent or not, all the items will be resend to broker, which will cause the redundancy of msg.
   We can add sent flag in pendingItemQueue initialized as false, which will be set to true after the corresponding buffer has been sent successfully.
   And filter the items which has been sent after the reconnection, resend the item which has not been sent only.
