Apache Atlas 中两种不同类型之间的名称关系链接

问题描述

我正在尝试命名两种不同类型之间的关系链接（通过使用 attributeDefs）。该关系现已注册到 Atlas 中，定义获取结果如下：

{
"category": "RELATIONSHIP","guid": "9b1059c3-8707-46db-ae3c-e8d1b4ef6333","createdBy": "admin","updatedBy": "admin","createTime": 1625233869809,"updateTime": 1625496519772,"version": 6,"name": "field_assignment","description": "someDescription.","typeVersion": "1.0","attributeDefs": [
    {
        "name": "Linkinformation","typeName": "string","isOptional": true,"cardinality": "SINGLE","valuesMinCount": 0,"valuesMaxCount": 1,"isUnique": false,"isIndexable": false,"includeInNotification": false,"searchWeight": -1
    }
],"relationshipCategory": "ASSOCIATION","propagateTags": "NONE","endDef1": {
    "type": "custom_dataset","name": "fields","isContainer": false,"cardinality": "SET","isLegacyAttribute": false
},"endDef2": {
    "type": "custom_field","name": "datasets","isLegacyAttribute": false
}

}

现在，我正在尝试在两种类型之间创建关系，同时为任一类型定义实体，例如

{
"entities": [
    {
        "typeName": "custom_field","guid": -1000,"attributes": {
            "name": "type","datasets": [
                {
                    "guid": "-200","typeName": "custom_dataset"
                }
            ]
        },"classifications": [],}
],"referredEntities": {
    "-200": {
        "guid": "-200","typeName": "custome_dataset","relationshipAttributes" : {"Linkinformation": "key"},"attributes": {
            "qualifiedname": "test"
        }
    }
}

}

通过，在执行此操作时，我没有看到任何错误并创建了实体，但通过简单地按 Linkinformation 搜索实体，GUID 为空。

...
"relationshipAttributes": {
                    "typeName": "field_assignment","attributes": {
                        "Linkinformation": null
                    }
                }
...

我无法在任何地方为此找到好的文档。有人可以帮忙吗？
