For more information, see Runtimes that are supported by Function Compute.

python3.9
timeoutinteger

The timeout period for the function to run. Unit: seconds. Default value: 60. Minimum value: 1. Maximum value: 600. When this period expires, the execution of the function is terminated.

10

9000
instanceConcurrencyinteger

The number of requests that can be concurrently processed by a single instance.

10
instanceSoftConcurrencyinteger

The soft concurrency of the instance. You can use this property to implement graceful scale-ups for instances. If the number of concurrent requests on an instance is greater than the soft concurrency value of the instance, an instance scale-up is triggered. For example, if your instance requires a long time to start, you can specify a suitable soft concurrency to start the instance in advance.

The value must be less than or equal to that of instanceConcurrency.
