SCF has certain quota limits for each user account.
The quota limits for a user account are as follows:
| Item | Default Quota Limit |
|---|---|
| Maximum number of functions in each namespace per region | 50 |
| Maximum number of concurrent executions per function | 300 |
| Maximum number of triggers per function | 10 |
| Maximum number of same-type triggers per function | 10 |
| Maximum code size of one function (version) (including bound layers) | 500 MB |
| Maximum total code size of functions per region | 100 GB |
| Maximum environment variable size of one function | 4 KB |
Note：
- SCF currently supports 10,000-level concurrence, which can effectively support scenarios with high concurrence demand such as ecommerce promotions and parallel processing of medical and biological data.
- For purposes of usage demand and security, the default maximum number of concurrent executions per function is set to 300. To request an increase in quota, please submit a ticket.
The limits for the function runtime environment are as follows:
| 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：
You can use API Gateway to pass a Base64-encoded file within 6 MB in SCF. To upload a Base64-encoded file greater than 6 MB, we recommend that you upload it to COS and give the object address to SCF, therefore SCF will pull the file from COS.
Currently, limits that can be increased include:
To increase the limits, please submit a ticket and state the desired items and quantities.
