Lambda Function

Docs > DDSQL Reference > Data Directory > Lambda Function

AWS Lambda Function is a serverless compute resource that runs code in response to events without provisioning or managing servers. It supports multiple runtimes, scales automatically, and charges only for execution time. Functions can be triggered by AWS services, HTTP requests, or custom events, making it ideal for event-driven applications, automation, and backend services.

Fields

ID	Type	Data Type	Description
_key	core	string
account_id	core	string
architectures	core	array<string>	The instruction set architecture that the function supports. Architecture is a string array with one of the valid values. The default architecture value is x86_64.
code_sha256	core	string	The SHA256 hash of the function's deployment package.
code_size	core	int64	The size of the function's deployment package, in bytes.
dead_letter_config	core	json	The function's dead letter queue.
description	core	string	The function's description.
environment	core	json	The function's environment variables. Omitted from CloudTrail logs.
ephemeral_storage	core	json	The size of the function's /tmp directory in MB. The default value is 512, but can be any whole number between 512 and 10,240 MB. For more information, see Configuring ephemeral storage (console).
file_system_configs	core	json	Connection settings for an Amazon EFS file system.
function_arn	core	string	The function's Amazon Resource Name (ARN).
function_name	core	string	The name of the function.
function_url_configs	core	json	A list of function URL configurations.
handler	core	string	The function that Lambda calls to begin running your function.
image_config_response	core	json	The function's image configuration values.
kms_key_arn	core	string	The ARN of the Key Management Service (KMS) customer managed key that's used to encrypt the following resources: The function's environment variables. The function's Lambda SnapStart snapshots. When used with SourceKMSKeyArn, the unzipped version of the .zip deployment package that's used for function invocations. For more information, see Specifying a customer managed key for Lambda. The optimized version of the container image that's used for function invocations. Note that this is not the same key that's used to protect your container image in the Amazon Elastic Container Registry (Amazon ECR). For more information, see Function lifecycle. If you don't provide a customer managed key, Lambda uses an Amazon Web Services owned key or an Amazon Web Services managed key.
last_modified	core	string	The date and time that the function was last updated, in ISO-8601 format (YYYY-MM-DDThh:mm:ss.sTZD).
last_update_status	core	string	The status of the last update that was performed on the function. This is first set to Successful after function creation completes.
last_update_status_reason	core	string	The reason for the last update that was performed on the function.
last_update_status_reason_code	core	string	The reason code for the last update that was performed on the function.
layers	core	json	The function's layers.
logging_config	core	json	The function's Amazon CloudWatch Logs configuration settings.
master_arn	core	string	For Lambda@Edge functions, the ARN of the main function.
memory_size	core	int64	The amount of memory available to the function at runtime.
package_type	core	string	The type of deployment package. Set to Image for container image and set Zip for .zip file archive.
policies	core	json
policy	core	json	The resource-based policy.
provisioned_concurrency_configs	core	json	A list of provisioned concurrency configurations.
revision_id	core	string	The latest updated revision of the function or alias.
role	core	string	The function's execution role.
runtime	core	string	The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image. The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation. For a list of all currently supported runtimes, see Supported runtimes.
runtime_version_config	core	json	The ARN of the runtime and any errors that occured.
signing_job_arn	core	string	The ARN of the signing job.
signing_profile_version_arn	core	string	The ARN of the signing profile version.
snap_start	core	json	Set ApplyOn to PublishedVersions to create a snapshot of the initialized execution environment when you publish a function version. For more information, see Improving startup performance with Lambda SnapStart.
state	core	string	The current state of the function. When the state is Inactive, you can reactivate the function by invoking it.
state_reason	core	string	The reason for the function's current state.
state_reason_code	core	string	The reason code for the function's current state. When the code is Creating, you can't invoke or modify the function.
tags	core	hstore
timeout	core	int64	The amount of time in seconds that Lambda allows a function to run before stopping it.
tracing_config	core	json	The function's X-Ray tracing configuration.
version	core	string	The version of the Lambda function.
vpc_config	core	json	The function's networking configuration.
