接口 Function<I,​O>

public interface Function<I,​O>
    This is the core interface of the function api. The process is called for every message of the input topic of the function. The incoming input bytes are converted to the input type I for simple Java types(String, Integer, Boolean, Map, and List types) and for org.Json type. If this serialization approach does not meet your needs, you can use the byte stream handler defined in RawRequestHandler.
