Name formats .title
Function name - my-function.
Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function.
Partial ARN - 123456789012:function:my-function.
The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.
The identifier of the function\'s runtime.
The Amazon Resource Name (ARN) of the function\'s execution role.
The name of the method within your code that Lambda calls to execute your function. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see Programming Model.
The code for the function.
A description of the function.
The amount of time that Lambda allows a function to run before stopping it. The default is 3 seconds. The maximum allowed value is 900 seconds.
The amount of memory that your function has access to. Increasing the function\'s memory also increases its CPU allocation. The default value is 128 MB. The value must be a multiple of 64 MB.
Set to true to publish the first version of the function during creation.
For network connectivity to AWS resources in a VPC, specify a list of security groups and subnets in the VPC. When you connect a function to a VPC, it can only access resources and the internet through that VPC. For more information, see VPC Settings.
A dead letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead Letter Queues.
Environment variables that are accessible from function code during execution.
The ARN of the AWS Key Management Service (AWS KMS) key that\'s used to encrypt your function\'s environment variables. If it\'s not provided, AWS Lambda uses a default service key.
Set Mode to Active to sample and trace a subset of incoming requests with AWS X-Ray.
A list of tags to apply to the function.
A list of function layers to add to the function\'s execution environment. Specify each layer by its ARN, including the version.
Connection settings for an Amazon EFS file system.
