Avro架构定义中的警告

Question

我得到了一个定义字段的警告：

Ignored the logicalType property ("timestamp-millis"). It should probably be nested inside the "type" for the field.

{"name": "leaving", "type": ["null" ,"long"], "logicalType": "timestamp-millis", "default": null, "doc": "leaving timestamp"}

我试图将其更改为：

{"name": "leaving", "type": {"type": ["null" ,{"type": "long", "logicalType": "timestamp-millis"}]}, "doc": "leaving timestamp"}

现在它根本不起作用，因为模式无效。

错误：

InvocationTargetException: No type: {"type":["null",{"type":"long","logicalType":"timestamp-millis"}]} 

知道怎么解决吗？

Answer 1

您有重复的类型。应该是这样的

{
  "name": "leaving",
  "type": ["null" , {"type": "long", "logicalType": "timestamp-millis"}],
  "doc": "leaving timestamp"
}
