Esper嵌套事件表示

Question

我想使用Esper处理以下JSON消息：

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

声明事件类型架构的正确方法是什么？有人可以帮我构建一个正确的：create schema (); EPL在线声明吗？ 谢谢！

Answer 1

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