使用avro模式验证大小为动态的json对象数组

我正在尝试验证json对象的数组,这些对象的大小在apachenifi中是动态的。我知道如果大小已知,我们可以编写一个模式来验证。即使大小是动态的,也有方法验证。

Json条目如下所示

"multi_location" : [
        {
            "cityState" : "Seattle, Washington", 
            "country" : "United States", 
            "city" : "Seattle", 
            "location" : "Seattle, Washington, United States", 
            "cityCountry" : "Seattle, United States", 
            "cityStateCountry" : "Seattle, Washington, United States", 
            "state" : "Washington", 
            "mapQueryLocation" : "Seattle, Washington, United States", 
            "stateCountry" : "Washington, United States"
        }, 
        {
            "cityState" : "Toronto, Ontario", 
            "country" : "Canada", 
            "city" : "Toronto", 
            "location" : "Toronto, Ontario, Canada", 
            "cityCountry" : "Toronto, Canada", 
            "cityStateCountry" : "Toronto, Ontario, Canada", 
            "state" : "Ontario", 
            "mapQueryLocation" : "Toronto, Ontario, Canada", 
            "stateCountry" : "Ontario, Canada"
        }, 
        {
            "cityState" : "Vancouver, British Columbia", 
            "country" : "Canada", 
            "city" : "Vancouver", 
            "location" : "Vancouver, British Columbia, Canada", 
            "cityCountry" : "Vancouver, Canada", 
            "cityStateCountry" : "Vancouver, British Columbia, Canada", 
            "state" : "British Columbia", 
            "mapQueryLocation" : "Vancouver, British Columbia, Canada", 
            "stateCountry" : "British Columbia, Canada"
        }
    ]
