Lambda
Overview

Lambda is a compute service that lets you run code without provisioning or managing servers. Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, code monitoring and logging. With Lambda, you can run code for virtually any type of application or backend service. For more information about the Lambda service, see What is Lambda in the Lambda Developer Guide.

The Lambda API Reference provides information about each of the API methods, including details about the parameters in each API request and response.

You can use Software Development Kits (SDKs), Integrated Development Environment (IDE) Toolkits, and command line tools to access the API. For installation instructions, see Tools for Amazon Web Services.

For a list of Region-specific endpoints that Lambda supports, see Lambda endpoints and quotas in the Amazon Web Services General Reference..

When making the API calls, you will need to authenticate your request by providing a signature. Lambda supports signature version 4. For more information, see Signature Version 4 signing process in the Amazon Web Services General Reference..

CA certificates

Because Amazon Web Services SDKs use the CA certificates from your computer, changes to the certificates on the Amazon Web Services servers can cause connection failures when you attempt to use an SDK. You can prevent these failures by keeping your computer's CA certificates and operating system up-to-date. If you encounter this issue in a corporate environment and do not manage your own computer, you might need to ask an administrator to assist with the update process. The following list shows minimum operating system and Java versions:
- Microsoft Windows versions that have updates from January 2005 or later installed contain at least one of the required CAs in their trust list.
- Mac OS X 10.4 with Java for Mac OS X 10.4 Release 5 (February 2007), Mac OS X 10.5 (October 2007), and later versions contain at least one of the required CAs in their trust list.
- Red Hat Enterprise Linux 5 (March 2007), 6, and 7 and CentOS 5, 6, and 7 all contain at least one of the required CAs in their default trusted CA list.
- Java 1.4.2_12 (May 2006), 5 Update 2 (March 2005), and all later versions, including Java 6 (December 2006), 7, and 8, contain at least one of the required CAs in their default trusted CA list.
When accessing the Lambda management console or Lambda API endpoints, whether through browsers or programmatically, you will need to ensure your client machines support any of the following CAs:
- Amazon Root CA 1
- Starfield Services Root Certificate Authority - G2
- Starfield Class 2 Certification Authority
Root certificates from the first two authorities are available from Amazon trust services, but keeping your computer up-to-date is the more straightforward solution. To learn more about ACM-provided certificates, see Amazon Web Services Certificate Manager FAQs.

  - addLayerVersionPermission
```
public AddLayerVersionPermissionResult addLayerVersionPermission(AddLayerVersionPermissionRequest request)
```
    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.
    
    Specified by:
    
    addLayerVersionPermission in interface AWSLambda
    
    Parameters:
    
    addLayerVersionPermissionRequest -
    
    Returns:
    
    Result of the AddLayerVersionPermission operation returned by the service.
    
    Throws:
    
    ServiceException - The Lambda service encountered an internal error.
    
    ResourceNotFoundException - The resource specified in the request does not exist.
    
    ResourceConflictException - The resource already exists, or another operation is in progress.
    
    TooManyRequestsException - The request throughput limit was exceeded.
    
    InvalidParameterValueException - One of the parameters in the request is invalid.
    
    PolicyLengthExceededException - The permissions policy for the resource is too large. Learn more
    
    PreconditionFailedException - The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the GetFunction or the GetAlias API to retrieve the latest RevisionId for your resource.

    AWS API Documentation
  - addPermission
```
public AddPermissionResult addPermission(AddPermissionRequest request)
```
    Grants an Amazon Web Services service or another account 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. For Amazon Web Services services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com. For Amazon Web Services 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 action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies.
    
    Specified by:
    
    addPermission in interface AWSLambda
    
    Parameters:

  - createFunction
```
public CreateFunctionResult createFunction(CreateFunctionRequest request)
```
    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 services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.
    
    You set the package type to Image if the deployment package is a container 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.
    
    You set the package type to Zip if the deployment package is a .zip file archive. 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, 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 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 set of signing profiles, which define the trusted publishers for this function.
    
    If another account or an Amazon Web Services service invokes your function, use AddPermission to grant permission by creating a resource-based 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 services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Functions.

  - invoke
```
public InvokeResult invoke(InvokeRequest request)
```
    Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType to Event.
    
    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 Retry Behavior.
    
    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, limit errors, or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException if executing 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 be disconnected 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.

  - putFunctionConcurrency
```
public PutFunctionConcurrencyResult putFunctionConcurrency(PutFunctionConcurrencyRequest request)
```
    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 Managing Concurrency.
    
    Specified by:
    
    putFunctionConcurrency in interface AWSLambda

  - putFunctionEventInvokeConfig
```
public PutFunctionEventInvokeConfigResult putFunctionEventInvokeConfig(PutFunctionEventInvokeConfigRequest request)
```
    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.

  - updateEventSourceMapping
```
public UpdateEventSourceMappingResult updateEventSourceMapping(UpdateEventSourceMappingRequest request)
```
    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.
    The following error handling options are only available 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.
    Specified by:
    
    updateEventSourceMapping in interface AWSLambda
    
    Parameters:
    
    updateEventSourceMappingRequest -
    
    Returns:
    
    Result of the UpdateEventSourceMapping operation returned by the service.
    
    Throws:
    
    ServiceException - The Lambda service encountered an internal error.
    
    ResourceNotFoundException - The resource specified in the request does not exist.
    
    InvalidParameterValueException - One of the parameters in the request is invalid.
    
    TooManyRequestsException - The request throughput limit was exceeded.
    
    ResourceConflictException - The resource already exists, or another operation is in progress.
    
    ResourceInUseException - The operation conflicts with the resource's availability. For example, you attempted to update an EventSource Mapping in CREATING, or tried to delete a EventSource mapping currently in the UPDATING state.

  - updateFunctionCode
```
public UpdateFunctionCodeResult updateFunctionCode(UpdateFunctionCodeRequest request)
```
    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.
    
    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.
    
    Specified by:
    
    updateFunctionCode in interface AWSLambda
    
    Parameters:
    
    updateFunctionCodeRequest -
    
    Returns:
    
    Result of the UpdateFunctionCode operation returned by the service.
    
    Throws:
    
    ServiceException - The Lambda service encountered an internal error.
    
    ResourceNotFoundException - The resource specified in the request does not exist.
    
    InvalidParameterValueException - One of the parameters in the request is invalid.
    
    TooManyRequestsException - The request throughput limit was exceeded.
    
    CodeStorageExceededException - You have exceeded your maximum total code size per account. Learn more
    
    PreconditionFailedException - The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the GetFunction or the GetAlias API to retrieve the latest RevisionId for your resource.
    
    ResourceConflictException - The resource already exists, or another operation is in progress.
    
    CodeVerificationFailedException - The code signature failed one or more of the validation checks for signature mismatch or expiry, and the code signing policy is set to ENFORCE. Lambda blocks the deployment.
    
    InvalidCodeSignatureException - The code signature failed the integrity check. Lambda always blocks deployment if the integrity check fails, even if code signing policy is set to WARN.
    
    CodeSigningConfigNotFoundException - The specified code signing configuration does not exist.

  - updateFunctionConfiguration
```
public UpdateFunctionConfigurationResult updateFunctionConfiguration(UpdateFunctionConfigurationRequest request)
```
    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 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 account or Amazon Web Services service, use AddPermission.

  - getCachedResponseMetadata
```
public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.
    
    Specified by:
    
    getCachedResponseMetadata in interface AWSLambda
    
    Parameters:
    
    request - The originally executed request
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.

  - shutdown
```
public void shutdown()
```
    Description copied from interface: AWSLambda
    
    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
