艾斯波嵌套事件表示

Question

我要處理使用艾斯波以下JSON消息：

{ 
    "firstname":"John", 
    "lastname":"Do", 
    "address":[{"street":"Maplestreet","number":100,"city":"New York"}] 
} 

什麼是聲明的事件類型模式的正確方法是什麼？有人可以幫我構建正確的EPL：create schema();聲明嗎？ 謝謝！

Answer 1

create schema Address (street string, number int, city string); 
create schema Person (name string, address Address[]);
