Deleting the Direct Reading Configuration of a Bucket (SDK for Python)

Function

This API is used to delete the direct reading configuration of a bucket.

After the direct reading configuration is deleted, ArchiveCold objects in the bucket cannot be directly read. If you then perform operations on ArchiveCold objects that have not been restored or are being restored, a 403 Forbidden error will be returned.

For a bucket that has direct reading configured, you can delete the direct reading configuration of the bucket. After the deletion, ArchiveCold objects in the bucket cannot be directly read. For more information about direct reading, see Direct Reading.

Restrictions

  • The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
  • Direct reading is not available for fusion buckets.

Method

ObsClient.deleteBucketDirectColdAccess(bucketName, extensionHeaders)

Request Parameters

Parameter

Type

Mandatory (Yes/No)

Bucket name

Restrictions:

  • A bucket name must be unique across all accounts and regions.
  • A bucket name:

    • Cannot be formatted as an IP address.

    • Cannot contain two consecutive periods (..), for example, my..bucket.
    • Cannot contain a period (.) and a hyphen (-) adjacent to each other, for example, my-.bucket or my.-bucket.
  • If you repeatedly create buckets with the same name in the same region, no error will be reported and the bucket properties comply with those set in the first creation request.
