我有一个json对象

{ 
  "timestamp": "2020-06-24T15:32:56.775518Z",
  "record-type": "data",
  "operation": "load",
  "partition-key-type": "primary-key",
  "schema-name": "legacy",
  "table-name": "test"
}

我想把这些记录反序列化成

class MetadataModel(faust.Record):
    timestamp: str
    record-type: str  # does not work, hyphens in name not allowed
    schema_name: str  # does not work
    tableName: str    # does not work

我可能遗漏了一些简单的东西，但是如何从键中带有连字符的json对象转到python对象呢。任何帮助都将不胜感激！
