Lambda

add_layer_version_permission(action, layer_name, principal, statement_id, version_number)
add_layer_version_permission(action, layer_name, principal, statement_id, version_number, params::Dict{String,<:Any})

Adds permissions to the resource-based policy of a version of an Lambda layer. Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts. To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.

Arguments

• action: The API action that grants access to the layer. For example, lambda:GetLayerVersion.
• layer_name: The name or Amazon Resource Name (ARN) of the layer.
• principal: An account ID, or * to grant layer usage permission to all accounts in an organization, or all Amazon Web Services accounts (if organizationId is not specified). For the last case, make sure that you really do want all Amazon Web Services accounts to have usage permission to this layer.
• statement_id: An identifier that distinguishes the policy from others on the same layer version.
• version_number: The version number.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "OrganizationId": With the principal set to *, grant permission to all accounts in the specified organization.
• "RevisionId": Only update the policy if the revision ID matches the ID specified. Use this option to avoid modifying a policy that has changed since you last read it.

add_permission(action, function_name, principal, statement_id)
add_permission(action, function_name, principal, statement_id, params::Dict{String,<:Any})

Grants an Amazon Web Service, Amazon Web Services account, or Amazon Web Services organization permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. Note: Lambda does not support adding policies to version LATEST. To grant permission to another account, specify the account ID as the Principal. To grant permission to an organization defined in Organizations, specify the organization ID as the PrincipalOrgID. For Amazon Web Services, the principal is a domain-style identifier that the service defines, such as s3.amazonaws.com or sns.amazonaws.com. For Amazon Web Services, you can also specify the ARN of the associated resource as the SourceArn. If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function. This operation adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Using resource-based policies for Lambda.

Arguments

• action: The action that the principal can use on the function. For example, lambda:InvokeFunction or lambda:GetFunction.
• function_name: The name or ARN of the Lambda function, version, or alias. Name formats Function name – my-function (name-only), my-function:v1 (with alias). Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function. Partial ARN – 123456789012:function:my-function. You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.
• principal: The Amazon Web Service or Amazon Web Services account that invokes the function. If you specify a service, use SourceArn or SourceAccount to limit who can invoke the function through that service.
• statement_id: A statement identifier that differentiates the statement from others in the same policy.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "EventSourceToken": For Alexa Smart Home functions, a token that the invoker must supply.
• "FunctionUrlAuthType": The type of authentication that your function URL uses. Set to AWS_IAM if you want to restrict access to authenticated users only. Set to NONE if you want to bypass IAM authentication to create a public endpoint. For more information, see Security and auth model for Lambda function URLs.
• "PrincipalOrgID": The identifier for your organization in Organizations. Use this to grant permissions to all the Amazon Web Services accounts under this organization.
• "Qualifier": Specify a version or alias to add permissions to a published version of the function.
• "RevisionId": Update the policy only if the revision ID matches the ID that's specified. Use this option to avoid modifying a policy that has changed since you last read it.
• "SourceAccount": For Amazon Web Service, the ID of the Amazon Web Services account that owns the resource. Use this together with SourceArn to ensure that the specified account owns the resource. It is possible for an Amazon S3 bucket to be deleted by its owner and recreated by another account.
• "SourceArn": For Amazon Web Services, the ARN of the Amazon Web Services resource that invokes the function. For example, an Amazon S3 bucket or Amazon SNS topic. Note that Lambda configures the comparison using the StringLike operator.

create_alias(function_name, function_version, name)
create_alias(function_name, function_version, name, params::Dict{String,<:Any})

Creates an alias for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

• "DocumentDBEventSourceConfig": Specific configuration settings for a DocumentDB event source.
• "Enabled": When true, the event source mapping is active. When false, Lambda pauses polling and invocation. Default: True
• "EventSourceArn": The Amazon Resource Name (ARN) of the event source. Amazon Kinesis – The ARN of the data stream or a stream consumer. Amazon DynamoDB Streams – The ARN of the stream. Amazon Simple Queue Service – The ARN of the queue. Amazon Managed Streaming for Apache Kafka – The ARN of the cluster or the ARN of the VPC connection (for cross-account event source mappings). Amazon MQ – The ARN of the broker. Amazon DocumentDB – The ARN of the DocumentDB change stream.

For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

create_function(code, function_name, role)
create_function(code, function_name, role, params::Dict{String,<:Any})

Creates a Lambda function. To create a function, you need a deployment package and an execution role. The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing. If the deployment package is a container image, then you set the package type to Image. For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties. If the deployment package is a .zip file archive, then you set the package type to Zip. For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64). If you do not specify the architecture, then the default value is x86-64. When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify the function. The State, StateReason, and StateReasonCode fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see Lambda function states. A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration. The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags (TagResource) and per-function concurrency limits (PutFunctionConcurrency). You can use code signing if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set of signing profiles, which define the trusted publishers for this function. If another Amazon Web Services account or an Amazon Web Service invokes your function, use AddPermission to grant permission by creating a resource-based Identity and Access Management (IAM) policy. You can grant permissions at the function level, on a version, or on an alias. To invoke your function directly, use Invoke. To invoke your function in response to events in other Amazon Web Services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Lambda functions.

• "ImageConfig": Container image configuration values that override the values in the container image Dockerfile.
• "KMSKeyArn": The ARN of the Key Management Service (KMS) customer managed key that's used to encrypt your function's environment variables. When Lambda SnapStart is activated, Lambda also uses this key is to encrypt your function's snapshot. If you deploy your function using a container image, Lambda also uses this key to encrypt your function when it's deployed. Note that this is not the same key that's used to protect your container image in the Amazon Elastic Container Registry (Amazon ECR). If you don't provide a customer managed key, Lambda uses a default service key.

• "Publish": Set to true to publish the first version of the function during creation.
• "Runtime": The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. The following list includes deprecated runtimes. For more information, see Runtime deprecation policy.
• "SnapStart": The function's SnapStart setting.
• "Tags": A list of tags to apply to the function.
• "Timeout": The amount of time (in seconds) that Lambda allows a function to run before stopping it. The default is 3 seconds. The maximum allowed value is 900 seconds. For more information, see Lambda execution environment.

invoke(function_name)
invoke(function_name, params::Dict{String,<:Any})

Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. By default, Lambda invokes your function synchronously (i.e. theInvocationType is RequestResponse). To invoke a function asynchronously, set InvocationType to Event. Lambda passes the ClientContext object to your function for synchronous invocations only. For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace. When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Error handling and automatic retries in Lambda. For asynchronous invocation, Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue. The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, quota errors, or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException if running the function would cause you to exceed a concurrency limit at either the account level (ConcurrentInvocationLimitExceeded) or function level (ReservedFunctionConcurrentInvocationLimitExceeded). For functions with a long timeout, your client might disconnect during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings. This operation requires permission for the lambda:InvokeFunction action. For details on how to set up permissions for cross-account invocations, see Granting function access to other accounts.

Arguments

• function_name: The name or ARN of the Lambda function, version, or alias. Name formats Function name – my-function (name-only), my-function:v1 (with alias). Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function. Partial ARN – 123456789012:function:my-function. You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

Optional Parameters

put_function_concurrency(function_name, reserved_concurrent_executions)
put_function_concurrency(function_name, reserved_concurrent_executions, params::Dict{String,<:Any})

Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level. Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function. Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Lambda function scaling.

Arguments

• function_name: The name or ARN of the Lambda function. Name formats Function name – my-function. Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

put_function_event_invoke_config(function_name)
put_function_event_invoke_config(function_name, params::Dict{String,<:Any})

Configures options for asynchronous invocation on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig. By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration. To send an invocation record to a queue, topic, function, or event bus, specify a destination. You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.

Arguments

• function_name: The name or ARN of the Lambda function, version, or alias. Name formats Function name - my-function (name-only), my-function:v1 (with alias).

Adds a provisioned concurrency configuration to a function's alias or version.

Arguments

• function_name: The name or ARN of the Lambda function. Name formats 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.
• provisioned_concurrent_executions: The amount of provisioned concurrency to allocate for the version or alias.
• qualifier: The version number or alias name.

put_runtime_management_config(function_name, update_runtime_on)

Arguments

• function_name: The name or ARN of the Lambda function. Name formats 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.
• update_runtime_on: Specify the runtime update mode. Auto (default) - Automatically update to the most recent and secure runtime version using a Two-phase runtime version rollout. This is the best choice for most customers to ensure they always benefit from runtime updates. Function update - Lambda updates the runtime of your function to the most recent and secure runtime version when you update your function. This approach synchronizes runtime updates with function deployments, giving you control over when runtime updates are applied and allowing you to detect and mitigate rare runtime update incompatibilities early. When using this setting, you need to regularly update your functions to keep their runtime up-to-date. Manual - You specify a runtime version in your function configuration. The function will use this runtime version indefinitely. In the rare case where a new runtime version is incompatible with an existing function, this allows you to roll back your function to an earlier runtime version. For more information, see Roll back a runtime version.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "Qualifier": Specify a version of the function. This can be LATEST or a published version number. If no value is specified, the configuration for the LATEST version is returned.

Updates an event source mapping. You can change the function that Lambda invokes, or pause invocation and resume later from the same location. For details about how to configure different event sources, see the following topics. Amazon DynamoDB Streams Amazon Kinesis Amazon SQS Amazon MQ and RabbitMQ Amazon MSK Apache Kafka Amazon DocumentDB The following error handling options are available only for stream sources (DynamoDB and Kinesis): BisectBatchOnFunctionError – If the function returns an error, split the batch in two and retry. DestinationConfig – Send discarded records to an Amazon SQS queue or Amazon SNS topic. MaximumRecordAgeInSeconds – Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires MaximumRetryAttempts – Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires. ParallelizationFactor – Process multiple batches from each shard concurrently. For information about which configuration parameters apply to each event source, see the following topics. Amazon DynamoDB Streams Amazon Kinesis Amazon SQS Amazon MQ and RabbitMQ Amazon MSK Apache Kafka Amazon DocumentDB

Arguments

• uuid: The identifier of the event source mapping.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

• "BatchSize": The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB). Amazon Kinesis – Default 100. Max 10,000. Amazon DynamoDB Streams – Default

• "DestinationConfig": (Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Kafka only) A configuration object that specifies the destination of an event after Lambda processes it.
• "DocumentDBEventSourceConfig": Specific configuration settings for a DocumentDB event source.
• "Enabled": When true, the event source mapping is active. When false, Lambda pauses polling and invocation. Default: True
• "FilterCriteria": An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.
• "FunctionName": The name or ARN of the Lambda function. Name formats Function name – MyFunction. Function ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction. Version or Alias ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD. Partial ARN – 123456789012:function:MyFunction. The length constraint applies only to the full ARN. If you specify only the function name, it's limited to 64 characters in length.
• "FunctionResponseTypes": (Kinesis, DynamoDB Streams, and Amazon SQS) A list of current response type enums applied to the event source mapping.
• "MaximumBatchingWindowInSeconds": The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function.

For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping. Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

update_function_code(function_name)
update_function_code(function_name, params::Dict{String,<:Any})

Updates a Lambda function's code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing for Lambda. If the function's package type is Image, then you must specify the code package in ImageUri as the URI of a container image in the Amazon ECR registry. If the function's package type is Zip, then you must specify the deployment package as a .zip file archive. Enter the Amazon S3 bucket and key of the code .zip file location. You can also provide the function code inline using the ZipFile field. The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64). The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version. For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.

Arguments

• function_name: The name or ARN of the Lambda function. Name formats Function name – my-function. Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

• "DryRun": Set to true to validate the request parameters and access permissions without modifying the function code.
• "ImageUri": URI of a container image in the Amazon ECR registry. Do not use for a function defined with a .zip file archive.
• "Publish": Set to true to publish a new version of the function after updating the code. This has the same effect as calling PublishVersion separately.
• "RevisionId": Update the function only if the revision ID matches the ID that's specified. Use this option to avoid modifying a function that has changed since you last read it.
• "S3Bucket": An Amazon S3 bucket in the same Amazon Web Services Region as your function. The bucket can be in a different Amazon Web Services account. Use only with a function defined with a .zip file archive deployment package.
• "S3Key": The Amazon S3 key of the deployment package. Use only with a function defined with a .zip file archive deployment package.
• "S3ObjectVersion": For versioned objects, the version of the deployment package object to use.

update_function_configuration(function_name)
update_function_configuration(function_name, params::Dict{String,<:Any})

Modify the version-specific settings of a Lambda function. When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can't modify the function, but you can still invoke it. The LastUpdateStatus, LastUpdateStatusReason, and LastUpdateStatusReasonCode fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see Lambda function states. These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version. To configure function concurrency, use PutFunctionConcurrency. To grant invoke permissions to an Amazon Web Services account or Amazon Web Service, use AddPermission.

Arguments

• function_name: The name or ARN of the Lambda function. Name formats Function name – my-function. Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.
