This topic describes the limits of Intelligent Media Management (IMM), the regions where it is available, and the features supported in each region.
Quotas
The following table describes the default quotas.
Parameter Name | Default value | Description |
MaxUserProjectCount | 100 | The maximum number of projects that a user can create. |
ProjectQueriesPerSecond | 100 | The maximum number of requests that a project can process per second. This is the total number of API calls that are allowed per second for the project. |
EngineConcurrency | 100 | The maximum number of tasks that a project can process per second. This is the maximum number of operators in the project that can run in parallel.
|
ProjectMaxDatasetCount | 1,000,000,000 | The maximum number of datasets in a project. The value must be in the range of 1 to 1,000,000,000. |
DatasetMaxBindCount | 10 | The maximum number of times a dataset can be attached. The value must be in the range of 1 to 10. |
DatasetMaxFileCount | 100,000,000 | The maximum number of files in a dataset. The value must be in the range of 1 to 100,000,000. |
DatasetMaxEntityCount | 10,000,000,000 | The maximum number of metadata entities in each dataset. Note This parameter is reserved and does not impose an actual limit. |
DatasetMaxRelationCount | 100,000,000,000 | The maximum number of metadata relationships in each dataset. Note This parameter is reserved and does not impose an actual limit. |
DatasetMaxTotalFileSize | 90,000,000,000,000,000 | The maximum total size of files in a dataset. If this limit is exceeded, you can no longer add indexes. Unit: bytes. |
Image limits
Supported image formats: JPG, PNG, BMP, GIF, WEBP, TIFF, and HEIC.
The height or width of the source image cannot exceed 30,000 pixels, and the total number of pixels cannot exceed 250 million.
For animated images, such as GIF images, the number of pixels is calculated as: width × height × number of frames.
For still images, such as PNG images, the number of pixels is calculated as: width × height.
GIF images are supported by all features except for QR code detection. For GIF images, only the first frame is used for detection.
The QR code detection feature can detect a maximum of five QR codes in a single image.
When you input an image in WEBP, TIFF, or HEIC format, Intelligent Media Management automatically uses the OSS format conversion feature to convert the image and then performs AI processing.
ImportantThis process may incur conversion fees. For more information about billing, see Billing overview.
The maximum size of an input image is 20 MB. For QR code detection, the minimum size of an input image is 40 × 40 pixels.
There is no limit on the number of faces in an image. By default, all detected faces are returned. The detection time depends on the image size, and larger images take longer to process.
Requests to process oversized images may time out. If a timeout occurs, you can reduce the image size and try again.
Document limits
QPS limit for the document conversion API
A single user is limited to 50 queries per second (QPS) when calling the CreateOfficeConversionTask operation.
