layers	array	The list of layers. Multiple layers are merged in descending order of their array index. The content of a layer with a smaller index overwrites files with the same name in layers with a larger index.
	string	The ARN of the layer.	acs:fc:cn-beijing:186824xxxxxx:layers/fc_layer/versions/1
logConfig	LogConfig	The log configuration. The logs generated by the function are written to the specified Logstore.

nasConfig	NASConfig	The NAS configuration. After you configure this parameter, the function can access the specified NAS resources.
ossMountConfig	OSSMountConfig	The OSS mount configuration.
role	string	The RAM role that grants Function Compute the required permissions. Scenarios include the following: 1. Sending logs generated by the function to your Logstore. 2. Generating temporary access tokens for the function to access other cloud resources during execution.	acs:ram::188077086902****:role/fc-test
runtime	string	The runtime environment of the function.	nodejs14
timeout	integer	The timeout period for the function to run. Unit: seconds. The minimum value is 1 second. The default value is 3 seconds. The function execution is stopped if it runs longer than this period.	60
tracingConfig	TracingConfig	The Tracing Analysis configuration. After you integrate Function Compute with Tracing Analysis, you can record the time consumed by requests in Function Compute, view the cold start time of functions, and record the time consumed by internal function operations.
vpcConfig	VPCConfig	The VPC configuration. After you configure this parameter, the function can access the specified VPC resources.
disableOndemand	boolean	Specifies whether to disable the creation of on-demand instances. If you enable this feature, on-demand instances are not created. Only provisioned instances can be used.
sessionAffinity	string	The affinity policy for Function Compute invocation requests. To implement request affinity for the MCP SSE protocol, set this parameter to MCP_SSE. To use cookie-based affinity, set this parameter to GENERATED_COOKIE. To use header-based affinity, set this parameter to HEADER_FIELD. If you do not set this parameter or set it to NONE, no affinity is used, and requests are routed based on the default scheduling policy of Function Compute.	MCP_SSE
enableLongLiving	boolean	Specifies whether to allow provisioned instances of GPU-accelerated functions to be long-living. If you enable this feature, the created function instances are not injected with STS tokens.
instanceIsolationMode	string	The instance isolation mode.
sessionAffinityConfig	string	When you set the sessionAffinity type, you must set the related affinity configuration. For MCP_SSE affinity, fill in the MCPSSESessionAffinityConfig configuration. For cookie-based affinity, fill in the CookieSessionAffinityConfig configuration. For header field-based affinity, fill in the HeaderFieldSessionAffinityConfig configuration.	{\"sseEndpointPath\":\"/sse\", \"sessionConcurrencyPerInstance\":20}
