抛出:

Exception

invoke

default void invoke(IN value,
                    SinkFunction.Context context)
             throws Exception

Writes the given value to the sink. This function is called for every record.

You have to override this method when implementing a SinkFunction, this is a default method for backward compatibility with the old-style method only.

参数:

value - The input record.

context - Additional context about the input record.

抛出:

Exception - This method may throw exceptions. Throwing an exception will cause the operation to fail and may trigger recovery.
