   > If I understand correctly. Invoke the method `setConsumeMessageBatchMaxSize()` on your builder to specify the message consumption batch size (`DefaultMQPushConsumer#consumeMessageBatchMaxSize`) you want. By default, `consumeMessageBatchMaxSize = 1`. By viewing the method `ConsumeMessageConcurrentlyService#submitConsumeRequest(4)`, you can understand the implementation details of consumption batching.
   
   in version 5  not exist DefaultMQPushConsumer  class
