Avro Schema 定義中的警告

Question

我收到了一個已定義字段的警告：

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"}

我試圖將其更改為：

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

現在由於架構無效，它根本不起作用。

錯誤：

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

知道如何解決嗎？

Answer 1

你有重復的type 。 它應該是

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