timeout	Integer	Maximum duration the function can be executed. Value range: 3s–900s. The value can be up to 12 hours for whitelisted users. For details, contact FunctionGraph personnel.
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.
gpu_memory	Integer	GPU memory. This parameter is available only for functions created with a custom runtime or image. Unit: MB. Options: 1024, 2048, 3072, 4096, 5120, 6144, 7168, 8192, 9216, 10,240, 11,264, 12,288, 13,312, 14,336, 15,360, and 16,384. Range: 1024 to 16,384.
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. The value is calculated as follows: Memory/128 x 100 + 200 (basic CPU millicores)
code_type	String	Function code type. Options: inline: inline code. zip: ZIP file. obs: function code stored in an OBS bucket. jar: JAR file, for Java functions. Enumeration values: inline zip obs jar
code_url	String	If CodeType is set to obs, enter the OBS URL of the function code package. If CodeType is not set to obs, leave this parameter blank.
code_filename	String	Name of a function file. This parameter is mandatory only when CodeType 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.
app_xrole	String	Agency used by the function app. You need to create an agency on the IAM console. This field is mandatory when a function needs to access other services.
description	String	Function description.
last_modified	String	Time when the function was last updated.
func_vpc_id	String	VPC ID.
strategy_config	StrategyConfig object	Function policy configuration.
extend_config	String	Extended configuration.
initializer_handler	String	Initializer of the function. It is in the format of "xx.xx" and must contain a period (.). 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.
enterprise_project_id	String	Enterprise project ID. This parameter is mandatory if you create a function as an enterprise user.
long_time	Boolean	Whether to allow a long timeout.
log_group_id	String	Log group ID.
log_stream_id	String	Log stream ID.
type	String	v2 indicates the OBT version and v1 indicates the original version. Enumeration values: v1 v2
