This topic provides frequently asked questions about limits in Intelligent Media Management (IMM).
Does Intelligent Media Management have concurrency limits, and how can they be adjusted?
Yes, IMM applies a limit on the concurrency level. For more information, see Quotas. If the number of requests exceeds the limit, subsequent requests are rejected.
If your application returns errors due to the concurrency limit, you can fix the errors using the following methods:
You can add waiting logic because the limit resets every second.
Pool requests and balance request traffic between peak hours and non-peak hours to avoid short-term traffic spikes.
If necessary, increase the concurrency limit. To increase the limit, contact us and provide the following information:
The project name, the region of your project, and the ID of your Alibaba Cloud account
Specific features in use
The expected number of daily calls and required concurrency level
If you are using a legacy project, we recommend migrating to the new version to access a higher quota. Quota adjustments are no longer supported for legacy projects.
What can I do if I want to create more projects than the default limit allows?
We recommend that you do not create too many projects.
If your application requires more projects, contact us and provide the following information:
Your region
The ID of your Alibaba Cloud account
The name of your project
Why can't I find my project?
Region mismatch
A project belongs to a specific region. For a list of supported regions, see Regions and supported features.
You cannot find the project if the specified region does not match the region of the project. When you encounter a no project error, log on to the IMM console, switch to the region, and check whether the project exists. If the project does not exist in the region, create one.
Issues with the independence of old and new projects

No, it is not.
Does IMM support buckets in Alibaba Finance Cloud?
IMM is not currently supported in Finance Cloud.
How can I limit the number of API calls to prevent unauthorized calls or accidental operations?
