AWS Lambda

Overview

This is the AWS Lambda API Reference. The AWS Lambda Developer Guide provides additional information. For the service overview, go to What is AWS Lambda, and for information about how the service works, go to AWS Lambda: How it Works in the AWS Lambda Developer Guide.

See: AWS API Reference

Service Configuration

lambda :: Service

API version '2015-03-31' of the Amazon Lambda SDK configuration.

Errors

Error matchers are designed for use with the functions provided by Control.Exception.Lens. This allows catching (and rethrowing) service specific errors returned by Lambda.

PolicyLengthExceededException

_PolicyLengthExceededException :: AsError a => Getting (First ServiceError) a ServiceError

Lambda function access policy is limited to 20 KB.

UnsupportedMediaTypeException

_UnsupportedMediaTypeException :: AsError a => Getting (First ServiceError) a ServiceError

Prism for UnsupportedMediaTypeException' errors.

InvalidRequestContentException

_InvalidRequestContentException :: AsError a => Getting (First ServiceError) a ServiceError

The request body could not be parsed as JSON.

InvalidParameterValueException

_InvalidParameterValueException :: AsError a => Getting (First ServiceError) a ServiceError

One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.

RequestTooLargeException

_RequestTooLargeException :: AsError a => Getting (First ServiceError) a ServiceError

Prism for RequestTooLargeException' errors.

TooManyRequestsException

_TooManyRequestsException :: AsError a => Getting (First ServiceError) a ServiceError

Prism for TooManyRequestsException' errors.

ServiceException

_ServiceException :: AsError a => Getting (First ServiceError) a ServiceError

The AWS Lambda service encountered an internal error.

CodeStorageExceededException

_CodeStorageExceededException :: AsError a => Getting (First ServiceError) a ServiceError

Prism for CodeStorageExceededException' errors.

ResourceConflictException

_ResourceConflictException :: AsError a => Getting (First ServiceError) a ServiceError

The resource already exists.

ResourceNotFoundException

_ResourceNotFoundException :: AsError a => Getting (First ServiceError) a ServiceError

The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.

Waiters

Waiters poll by repeatedly sending a request until some remote success condition configured by the Wait specification is fulfilled. The Wait specification determines how many attempts should be made, in addition to delay and retry strategies.

Operations

Some AWS operations return results that are incomplete and require subsequent requests in order to obtain the entire result set. The process of sending subsequent requests to continue where a previous request left off is called pagination. For example, the ListObjects operation of Amazon S3 returns up to 1000 objects at a time, and you must send subsequent requests with the appropriate Marker in order to retrieve the next page of results.

Operations that have an AWSPager instance can transparently perform subsequent requests, correctly setting Markers and other request facets to iterate through the entire result set of a truncated API operation. Operations which support this have an additional note in the documentation.

Many operations have the ability to filter results on the server side. See the individual operation parameters for details.

eventSourceMappingConfiguration :: EventSourceMappingConfiguration

Creates a value of EventSourceMappingConfiguration with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• esmcEventSourceARN
• esmcState
• esmcFunctionARN
• esmcUUId
• esmcLastProcessingResult
• esmcBatchSize
• esmcStateTransitionReason
• esmcLastModified

esmcEventSourceARN :: Lens' EventSourceMappingConfiguration (Maybe Text)

The Amazon Resource Name (ARN) of the Amazon Kinesis stream that is the source of events.

esmcState :: Lens' EventSourceMappingConfiguration (Maybe Text)

The state of the event source mapping. It can be "Creating", "Enabled", "Disabled", "Enabling", "Disabling", "Updating", or "Deleting".

esmcFunctionARN :: Lens' EventSourceMappingConfiguration (Maybe Text)

The Lambda function to invoke when AWS Lambda detects an event on the stream.

esmcUUId :: Lens' EventSourceMappingConfiguration (Maybe Text)

The AWS Lambda assigned opaque identifier for the mapping.

esmcLastProcessingResult :: Lens' EventSourceMappingConfiguration (Maybe Text)

The result of the last AWS Lambda invocation of your Lambda function.

esmcBatchSize :: Lens' EventSourceMappingConfiguration (Maybe Natural)

The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function. Your function receives an event with all the retrieved records.

esmcStateTransitionReason :: Lens' EventSourceMappingConfiguration (Maybe Text)

The reason the event source mapping is in its current state. It is either user-requested or an AWS Lambda-initiated state transition.

esmcLastModified :: Lens' EventSourceMappingConfiguration (Maybe UTCTime)

The UTC time string indicating the last time the event mapping was updated.

functionCode :: FunctionCode

Creates a value of FunctionCode with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• fcS3ObjectVersion
• fcS3Key
• fcZipFile
• fcS3Bucket

fcS3ObjectVersion :: Lens' FunctionCode (Maybe Text)

The Amazon S3 object (the deployment package) version you want to upload.

fcS3Key :: Lens' FunctionCode (Maybe Text)

The Amazon S3 object (the deployment package) key name you want to upload.

fcZipFile :: Lens' FunctionCode (Maybe ByteString)

A base64-encoded .zip file containing your deployment package. For more information about creating a .zip file, go to Execution Permissions in the AWS Lambda Developer Guide.

Note: This Lens automatically encodes and decodes Base64 data, despite what the AWS documentation might say. The underlying isomorphism will encode to Base64 representation during serialisation, and decode from Base64 representation during deserialisation. This Lens accepts and returns only raw unencoded data.

fcS3Bucket :: Lens' FunctionCode (Maybe Text)

Amazon S3 bucket name where the .zip file containing your deployment package is stored. This bucket must reside in the same AWS region where you are creating the Lambda function.

FunctionCodeLocation

data FunctionCodeLocation

The object for the Lambda function location.

See: functionCodeLocation smart constructor.

Use one of the following lenses to modify other fields as desired:

• fclLocation
• fclRepositoryType

fclLocation :: Lens' FunctionCodeLocation (Maybe Text)

The presigned URL you can use to download the function's .zip file that you previously uploaded. The URL is valid for up to 10 minutes.

fcMemorySize :: Lens' FunctionConfiguration (Maybe Natural)

The memory size, in MB, you configured for the function. Must be a multiple of 64 MB.

fcRuntime :: Lens' FunctionConfiguration (Maybe Runtime)

The runtime environment for the Lambda function.

fcFunctionARN :: Lens' FunctionConfiguration (Maybe Text)

The Amazon Resource Name (ARN) assigned to the function.

fcRole :: Lens' FunctionConfiguration (Maybe Text)

The Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it executes your function to access any other Amazon Web Services (AWS) resources.

fcFunctionName :: Lens' FunctionConfiguration (Maybe Text)

The name of the function.

fcCodeSize :: Lens' FunctionConfiguration (Maybe Integer)

The size, in bytes, of the function .zip file you uploaded.

fcHandler :: Lens' FunctionConfiguration (Maybe Text)

The function Lambda calls to begin executing your function.

fcTimeout :: Lens' FunctionConfiguration (Maybe Natural)

The function execution time at which Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time. The default is 3 seconds.

fcLastModified :: Lens' FunctionConfiguration (Maybe Text)

The timestamp of the last time you updated the function.

fcDescription :: Lens' FunctionConfiguration (Maybe Text)

The user-provided description.
