Rabbitmq retrieve multiple messages using single synchronous call

Question

Is there a way to receive multiple message using a single synchronous call ?

When I know that there are N messages( N could be a small value less than 10) in the queue,

Answer 1

You can use a QueueingConsumer implementation of Consumer interface which allows you to retrieve several messages in a single request.

 QueueingConsumer queueingConsumer = new QueueingConsumer(channel);
 channel.basicConsume(plugin.getQueueName(), false, queueingConsumer);

 for(int i = 0; i < 10; i++){
    QueueingConsumer.Delivery delivery = queueingConsumer.nextDelivery(100);//read timeout in ms
    if(delivery == null){
      break;
    }
 }
