假设我有以下内容:
"properties" : {
"prop1": "propval",
"prop2": 5
"prop3": {"subprop1":"subpropval1","subprop2":"subpropval2"}
}
"testlist" : [
{"key": "item1", "key2": "value1"},
{"key": "item1", "key2": "value1"}
{"key": "item1", "key2": "value1"}
]
这是否可以加载到 Impala 中并且可以在无需指定架构的情况下进行查询?还是必须是没有列表/嵌套结构的“平面” avro 模式?
