我想有一个消费者池，并重用每个消费者。对吗？

KafkaConsumer consumer = createConsumer();
TopicPartition topicPartition = new TopicPartition("topic", 2);
consumer.assign(List.of(topicPartition));
consumer.seek(topicPartition, 41);

ConsumerRecords records = consumer.poll(0);
// use records...

// reuse kafka consumer 
consumer.unsubscribe();

topicPartition = new TopicPartition("topic", 1);
consumer.assign(List.of(topicPartition));
consumer.seek(topicPartition, 8);

records = consumer.poll(0);
// use records...

或者我应该在每次需要时创建新的消费者？
