Configuring Direct Reading for Archive Objects in a Bucket

Functions

The direct reading function means that you can directly perform operations on Archive objects without restoring them.

By default, direct reading is disabled on a bucket.

You can use this API to enable or disable direct reading for a bucket.

• When direct reading is enabled on a bucket:
  • You can directly perform operations on Archive objects in the bucket regardless of whether they have been restored.
  • If Archive objects are not restored, your operations on them will be charged separately.
• When direct reading is disabled on a bucket:
  • You need to restore Archive objects in the bucket before you can operate them.

To perform this operation, you must have the PutDirectColdAccessConfiguration permission. By default, only the bucket owner can perform this operation. The bucket owner can grant the permission to other users by configuring the bucket policy or user policy.

Direct reading is only available in some regions. For details, see Function Overview.
