timeout	Integer	Maximum duration the function can be executed. Value range: 3s-259,200s.
handler	String	Handler of a function in the format of "xx.xx". It must contain a period (.). For example, for Node.js function myfunction.handler, the file name is myfunction.js, and the handler function is handler.
memory_size	Integer	Memory consumed by a function. Unit: MB. The value can be 128, 256, 512, 768, 1024, 1280, 1536, 1792, 2048, 2560, 3072, 3584 or 4096. The value ranges from 128 to 4096.
cpu	Integer	CPU resources of a function. Unit: millicore (1 core = 1000 millicores). The value of this field is proportional to that of MemorySize. By default, 100 CPU millicores are required for 128 MB memory.
code_type	String	Function code type. Options: inline: inline code zip: ZIP file obs: function code stored in an OBS bucket jar: JAR file, mainly for Java functions Custom-Image-Swr: The function code comes from the SWR custom image. Enumeration values: inline zip obs jar Custom-Image-Swr
code_url	String	If code_type is set to obs, enter the OBS URL of the function code package. If code_type is not set to obs, leave this parameter blank.
code_filename	String	Name of a function file. This parameter is mandatory only when code_type is set to jar or zip.
code_size	Long	Code size in bytes.
user_data	String	Name/Value information defined for the function. These are parameters used in the function. For example, if a function needs to access a host, define Host={host_ip}. You can define a maximum of 20 such parameters, and their total length cannot exceed 4 KB.
encrypted_user_data	String	User-defined name/value to be encrypted.
digest	String	SHA512 hash value of function code, which is used to determine whether the function has changed.
version	String	Function version, which is automatically generated by the system. The version name is in the format of "vYYYYMMDD-HHMMSS" (v+year/month/day-hour/minute/second).
image_name	String	Internal identifier of a function version.
xrole	String	Agency used by the function. You need to create an agency on the IAM console. This field is mandatory when a function needs to access other services. After specifying a function execution agency, you can use the context method in the function handler to obtain a token, an AK, and an SK for accessing other cloud services. No agency is required if FunctionGraph does not access any cloud services.
app_xrole	String	Execution agency. You can optimize performance by configuring a separate agency for function execution, otherwise, the same agency is used for both execution and configuration.
last_modified	String	Time when the function was last updated.
func_vpc_id	String	VPC ID.
concurrency	Integer	0: A function is disabled. -1: A function is enabled.
concurrent_num	Integer	Number of concurrent instances.
strategy_config	StrategyConfig object	Function policy configuration.
initializer_handler	String	Initializer of the function in the format of "xx.xx". It must contain a period (.). This parameter is mandatory when the initialization function is configured. For example, for Node.js function myfunction.initializer, the file name is myfunction.js, and the initialization function is initializer.
initializer_timeout	Integer	Maximum duration the function can be initialized. Value range: 1s-300s. This parameter is mandatory when the initialization function is configured.
pre_stop_handler	String	The pre-stop handler of a function. The value must contain a period (.) in the format of xx.xx. For example, for Node.js function myfunction.pre_stop_handler, the file name is myfunction.js, and the initialization function is pre_stop_handler.
pre_stop_timeout	Integer	Maximum duration the function can be initialized. Value range: 1s-90s.
long_time	Boolean	Whether long-term running is supported.
function_async_config	FunctionAsyncConfig object	Return struct of the asynchronous execution notification settings.
type	String	Function version.
enable_dynamic_memory	Boolean	Whether to enable dynamic memory allocation.

enable_auth_in_header	Boolean	Whether to allow authentication information in the request header.
custom_image	CustomImage object	Container image.
reserved_instance_idle_mode	Boolean	Whether to enable idle mode for reserved instances.

**Table 6** StrategyConfig¶
Parameter	Type	Description
concurrency	Integer	Maximum number of instances for a single function. For v1, the value can be 0 or -1; for v2, it ranges from -1 to 1000. -1: The function has unlimited instances. 0: The function is disabled.
concurrent_num	Integer	Number of concurrent requests per instance. This parameter is supported only by v2. The value ranges from 1 to 1,000.

**Table 7** FunctionAsyncConfig¶

Parameter	Type	Description
destination	String	Object type. OBS SMN FunctionGraph Enumeration values: OBS SMN FunctionGraph
param	String	Parameters (in JSON format) corresponding to the target service. OBS: Parameters related to the bucket name, object directory prefix, and object expiration time are included. The object expiration time ranges from 0 to 365 days. If the value is 0, the object will not expire. SMN: The topic_urn parameter is included. FunctionGraph: The func_urn parameter is included.
