为什么 Datastore Export API 不支持 Nearline 存储类型?

Why Datastore Export API does not support Nearline storage types?

我们最近使用新的 Datastore Export API.

配置了自动数据存储导出到云存储

很明显,我们想使用 Nearline 个存储桶来存储我们的备份,但是当我们尝试将 Datastore 数据库导出到近线存储桶时,我们收到以下错误:

Caused by: com.google.api.client.http.HttpResponseException: 400 BAD_REQUEST
{
  "error": {
    "code": 400,
    "message": "Bucket xxx-xxx-xxx has storage class NEARLINE which is not supported. Must be one of regional, multi_regional, standard, durable_reduced_availability.",
    "errors": [
      {
        "message": "Bucket xxx-xxx-xxx has storage class NEARLINE which is not supported. Must be one of regional, multi_regional, standard, durable_reduced_availability.",
        "domain": "global",
        "reason": "badRequest"
      }
    ],
    "status": "INVALID_ARGUMENT"
  }
}

我没有在文档中找到任何关于应该使用的 Cloud Storage 存储桶类型的内容。

是文档错误还是服务错误?

这是正确的行为。由于导出写入 GCS 的方式,不支持 Nearline 和 Coldline。

您可以导出为标准,然后 change to nearline after. You can even automate this with a SetStorageClass lifecycle action
