Using DefaultLitePullConsumer, there are more than 10,000 messages in the queue that have not been consumed. In the case of setPullBatchSize(500), the number of messages obtained is 32.

enter image description here

` String group = "group_test";

String topic = "topic_test";
DefaultLitePullConsumer consumer = new DefaultLitePullConsumer();
DefaultLitePullConsumerImpl impl;

I tried setting setPullBatchSize, setPullThreadNums and consumerManageThreadPoolNums=6400, defaultQueryMaxNum=8400 in rocketmq server broke.conf. All changes did not make the message size of a single pull larger than 32
