banishee opened a new issue #59: setting the SequenceId can't have an effect on Message deduplication
URL: https://github.com/apache/pulsar-client-go/issues/59
 
 
   #### Expected behavior
   Preparation:  Enabling message deduplication.
    when I initialized the `ProducerMessage{}`,  the `SequenceID` parameter was set to a specific value before I call the `SendAsync()`. So, in theory, the first Message will be received by the broker, and the following Messages will be discarded because of the repeated  SequenceID
   
   #### Actual behavior
   I tested this situation more than one time. However, no messages were discarded.
   
   #### Steps to reproduce
   ```
   for i:=int64(0); i<100; i++ {
   		 ...
   	producer.SendAsync(ctx, &pulsar.ProducerMessage{Payload: msg, SequenceID: &i},func(msgID pulsar.MessageID, message *pulsar.ProducerMessage, e error) {...})
   }
   ```
   I run the code a few times, but the consumer received all messages.
   
   ```
   for i:=int64(0); i<100; i++ {
   		 ...
           k := int64(0)
   	producer.SendAsync(ctx, &pulsar.ProducerMessage{Payload: msg, SequenceID: &k},func(msgID pulsar.MessageID, message *pulsar.ProducerMessage, e error) {...})
   }
   ```
   or like this code, its still not work.
   
   #### System configuration
   docker: apachepulsar/pulsar-standalone:2.3.1 bin/pulsar standalone
