SCF has certain quota limits for each user account.
Content | Default Quota Limit |
---|---|
Total function code size per region | 100 GB |
Total function concurrency quota per region | 128,000 MB (Guangzhou, Shanghai, Beijing, Chengdu, and Hong Kong (China)) |
64,000 MB (Mumbai, Singapore, Tokyo, Toronto, Silicon Valley, Frankfurt, Shenzhen Finance, and Shanghai Finance) |
|
Number of namespaces per region | 5 |
Total concurrent function quota per namespace | You can purchase a function package to adjust the quota. |
Number of functions per namespace | 50 |
Content | Default Quota Limit |
---|---|
Function name length limit | 60 characters. The total length of the namespace name + function name cannot exceed 118 characters. |
Maximum code size (including bound layers) per function (version) before compression | 500 MB |
Maximum number of same-type triggers per function | 10 |
Maximum environment variable size per function | 4 KB |
Number of layer versions bound to one function version | 5 |
Content | Default Quota Limit |
---|---|
Number of layers per region | 20 |
Number of versions per layer | 200 |
Note:
- SCF currently supports one million MB-level concurrency, which can effectively support scenarios with high concurrency demand such as ecommerce promotions and parallel processing of medical and biological data.
- The concurrency quota per region on the SCF platform is shared by all functions by default. You can customize the function concurrency to meet your actual needs. If you want to increase the quotas or add concurrency quota management capabilities at the namespace granularity, you can directly purchase a function package.
- In SCF, a COS trigger has limits in two dimensions: SCF and COS, as detailed below:
- SCF dimension: One function can be bound to 10 COS triggers at most.
- COS dimension: The same event and prefix/suffix rule of one COS bucket can be bound to only one function.
Item | Quota Limit |
---|---|
Allocated memory | Minimum: 64 MB, maximum: 3,072 MB, in increments of 128 MB starting from 128 MB |
Temporary cache space; i.e., size of the /tmp directory |
512 MB |
Timeout period | Minimum: 1 second, maximum: 900 seconds |
Number of file descriptors | 1,024 |
Total processes and threads | 1,024 |
Sync request event size | 6 MB |
Sync request response size | 6 MB |
Async request event size | 128 KB |
Note:If the size of a Base64-encoded file is below 6 MB, you can pass the encoded file to SCF through API Gateway; otherwise, we recommend you upload the file to COS and pass the object address to SCF first. Then, SCF will pull the file from COS to complete the upload.
