Table 6 Permission

Constant

Description

READ

Read permission

A grantee with this permission for a bucket can obtain the list of objects, multipart uploads, bucket metadata, and object versions in the bucket.

A grantee with this permission for an object can obtain the object content and metadata.

WRITE

Write permission

A grantee with this permission for a bucket can upload, overwrite, and delete any object or part in the bucket.

Such permission for an object is not applicable.

READ_ACP

Permission to read ACL configurations

A grantee with this permission can obtain the ACL of a bucket or object.

A bucket or object owner has this permission for the bucket or object permanently.

WRITE_ACP

Permission to modify ACL configurations

A grantee with this permission can update the ACL of a bucket or object.

A bucket or object owner has this permission for the bucket or object permanently.

A grantee with this permission can modify the access control policy and thus the grantee obtains full access permissions.

FULL_CONTROL

Full control access, including read and write permissions for a bucket and its ACL, or for an object and its ACL.

A grantee with this permission for a bucket has READ, WRITE, READ_ACP, and WRITE_ACP permissions for the bucket.
