   ### Description
   
   inglong dataproxy sdk sender.java code in asyncSendMessage method such as:
   `       
    ConcurrentHashMap<String, QueueObject> tmpQueueMap = new 
ConcurrentHashMap<>();
    ConcurrentHashMap<String, QueueObject> msgQueueMap = 
callbacks.putIfAbsent(client.getChannel(), tmpQueueMap);
    if (msgQueueMap == null) {
               msgQueueMap = tmpQueueMap;
    }
   `
   can be optimized to like this to reduce the number of invalid objects
   `
   ConcurrentHashMap<String, QueueObject> msgQueueMap =
                   callbacks.computeIfAbsent(client.getChannel(), (k) -> new 
ConcurrentHashMap<>());
   `
