    Kafka's consumers are not thread-safe and cannot be multi-threaded.
    Kafka is not like other MQs. After consuming the data, it will be discarded directly, but will be stored by default. 7 days, automatically cleared after 7 days of storage, so you can start consumption from the beginning and
    start consumption from the specified setoff of the partition of the specified topic
