OSS usage restrictions and performance indicators

bandwidth

The maximum bandwidth limits for a single AliCloud account in various regions are as follows:

If the threshold is reached, the request will be streamed. When the request is flow controlled, the header returned by the request will carry x-oss-qos-delay-time: number 。 among number Is the duration of the request to be controlled, in ms. The upload request will return the exact duration of the flow control; The download request will return the duration of being controlled based on the flow control degree and file size.

QPS (Query Per Second)

The total QPS of a single AliCloud account is 10000, but under different read/write modes, the actual values can be as follows:

If you use a sequential prefix (such as timestamp or alphabetical order) in naming when uploading a large number of files, a large number of file index sets may be stored in a specific partition of the storage space. At this time, if your request rate is too high, the request rate will decline. It is recommended that you do not use file names with sequential prefixes when uploading a large number of files. For how to change the order prefix to a random prefix, see OSS Performance and Scalability Best Practices 。

Storage space (Bucket)

• The total number of storage spaces created by the same AliCloud account in the same region cannot exceed 100. If your business needs to create more storage space, please go to Quota Center Submit the application.

• The storage space name must be globally unique within the OSS range. For naming conventions for storage spaces, see Storage space naming 。

• After a storage space is created, its name, region, and storage type cannot be modified.

• The capacity of a single storage space is unlimited.

Object

• Size of uploaded file

  adopt Simple upload 、 Form upload 、 Append Upload To upload a single file, the size of the file cannot exceed 5 GB.

  adopt Fragment upload To upload a single file, the size of the file cannot exceed 48.8 TB.

• Rename file size

  The console only supports renaming files of 1 GB or less. For files of 1 GB or more, it is recommended to use the SDK or the command line ossutil tool. For more information, see rename file 。

• Number of deleted files

  You can delete up to 100 files at a time through the OSS console, 1000 files at a time through the SDK, and unlimited files at a time through the command line tool ossutil and the graphical management tool ossbrowser.

  warning

  The file cannot be recovered after deletion. Please be careful.

• Files with the same name are overwritten

  By default, if the uploaded file has the same name as the existing file, the existing file will be overwritten.

  warning

  The original file will be lost after the file is overwritten. Please be careful. To prevent files from being accidentally overwritten, you can enable version control for the bucket where the file is located, or carry parameters in the header of the upload request x-oss-forbid-overwrite And specify its value as true 。

Data unfreezing

Before accessing data of archive storage (archive direct reading is not enabled), cold archive storage, and deep cold archive storage types, data unfreezing needs to be completed. The higher the priority of unfreezing, the shorter the unfreezing time, and the higher the cost of data retrieval involved in unfreezing. For more information, see Data retrieval cost 。

Domain name binding

• Domain names bound to various regions in the mainland of China must be filed with the Ministry of Industry and Information Technology, while domain names bound to other regions do not need to be filed with the Ministry of Industry and Information Technology.

• A domain name can only be bound to one storage space, and a storage space can bind up to 100 domain names.

• There is no limit to the number of domain names that can be bound to an account.

Life cycle rules

• A storage space can be configured with up to 1000 life cycle rules.

• Execution completion time

  For lifecycle rules with no label configured

  • In East China 1 (Hangzhou), East China 2 (Shanghai), North China 2 (Beijing), North China 3 (Zhangjiakou), North China 6 (Ulanqab), South China 1 (Shenzhen), and Singapore, operations related to the life cycle of 1 billion or less (including object deletion, object storage type conversion, and fragment expiration) can be completed within 24 hours. If the life cycle related operations exceed 1 billion times, it may exceed 24 hours.

  • In other regions, operations related to the sub life cycle of 100 million or less can be completed within 24 hours. If the life cycle related operations exceed 100 million times, it may exceed 24 hours.

  For lifecycle rules with tags configured

  • In East China 1 (Hangzhou), East China 2 (Shanghai), North China 2 (Beijing), North China 3 (Zhangjiakou), North China 6 (Ulanqab), South China 1 (Shenzhen), and Singapore, operations related to the life cycle of 500 million or less (including object deletion, object storage type conversion, and fragment expiration) can be completed within 24 hours. If the life cycle related operations exceed 500 million times, it may exceed 24 hours.

  • In other regions, operations related to the life cycle of 50 million or less can be completed within 24 hours. If the life cycle related operations exceed 50 million times, it may exceed 24 hours.

  explain

  If version control is enabled for the storage space, each version of the object is recorded as an operation.

Back to source rule

• A storage space can be configured with up to 20 back to source rules.

• For the mirror image back to source, the default QPS of all regions in mainland China and Hong Kong is 2000, and the traffic is 2 Gbit/s; The default QPS for overseas regions is 1000 and the traffic is 1 Gbit/s.

Picture processing

• Picture restrictions

  • Original drawing

    • The image format only supports JPG PNG、BMP、GIF、WebP、TIFF、HEIC、AVIF。

    • The size of the original image cannot exceed 20 MB.

    • Except that the height or width of the original image corresponding to image rotation cannot exceed 4096 px, the height or width of the original image corresponding to other image operations cannot exceed 30000 px, and the total number of pixels cannot exceed 250 million px.

      The pixel calculation method of dynamic pictures (such as GIF pictures) is Width * Height * Picture Frames ； The pixel calculation method of non dynamic pictures (such as PNG pictures) is Width * Height 。

  • Picture after zooming

    The width or height cannot exceed 16384 px, and the total pixels cannot exceed 16777216 px.

• Style restrictions

  A maximum of 50 styles can be created in each storage space.

  explain

  If your business has more style requirements, please contact technical support 。

• Processing capacity limit

  • Image processing per second (based on the size of the original image)

    • East China 1 (Hangzhou), East China 2 (Shanghai), North China 2 (Beijing), North China 3 (Zhangjiakou), South China 1 (Shenzhen): 20 MB/s.

    • East China 1 (Hangzhou), East China 2 (Shanghai), North China 2 (Beijing), North China 3 (Zhangjiakou), South China 1 (Shenzhen): 50.

    • Other regions: 5.

  explain
