NAME

Paws::Lambda - Perl Interface to AWS AWS Lambda

CONTENTS

SYNOPSIS



  use Paws;

  my $obj = Paws->service(Lambda)->new;
  my $res = $obj->Method(
    Arg1 => $val1,
    Arg2 => [ V1, V2 ],
    # if Arg3 is an object, the HashRef will be used as arguments to the constructor
    # of the arguments type
    Arg3 => { Att1 => Val1 },
    # if Arg4 is an array of objects, the HashRefs will be passed as arguments to
    # the constructor of the arguments type
    Arg4 => [ { Att1 => Val1  }, { Att1 => Val2 } ],
  );



DESCRIPTION

AWS Lambda

<B>OverviewB>

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.

METHODS

    AddPermission(Action => Str, FunctionName => Str, Principal => Str, StatementId => Str, [SourceAccount => Str, SourceArn => Str])

Each argument is described in detail in: Paws::Lambda::AddPermission

Returns: a Paws::Lambda::AddPermissionResponse instance

Adds a permission to the access policy associated with the specified AWS Lambda function. In a push event model, the access policy attached to the Lambda function grants Amazon S3 or a user application permission for the Lambda lambda:Invoke action. For information about the push model, see AWS Lambda: How it Works. Each Lambda function has one access policy associated with it. You can use the AddPermission API to add a permission to the policy. You have one access policy but it can have multiple permission statements.

This operation requires permission for the lambda:AddPermission action.

    CreateEventSourceMapping(EventSourceArn => Str, FunctionName => Str, StartingPosition => Str, [BatchSize => Int, Enabled => Bool])

Each argument is described in detail in: Paws::Lambda::CreateEventSourceMapping

Returns: a Paws::Lambda::EventSourceMappingConfiguration instance

Identifies a stream as an event source for a Lambda function. It can be either an Amazon Kinesis stream or an Amazon DynamoDB stream. AWS Lambda invokes the specified function when records are posted to the stream.

This is the pull model, where AWS Lambda invokes the function. For more information, go to AWS Lambda: How it Works in the AWS Lambda Developer Guide.

This association between an Amazon Kinesis stream and a Lambda function is called the event source mapping. You provide the configuration information (for example, which stream to read from and which Lambda function to invoke) for the event source mapping in the request body.

Each event source, such as an Amazon Kinesis or a DynamoDB stream, can be associated with multiple AWS Lambda function. A given Lambda function can be associated with multiple AWS event sources.

This operation requires permission for the lambda:CreateEventSourceMapping action.

    CreateFunction(Code => Paws::Lambda::FunctionCode, FunctionName => Str, Handler => Str, Role => Str, Runtime => Str, [Description => Str, MemorySize => Int, Timeout => Int])

Each argument is described in detail in: Paws::Lambda::CreateFunction

Returns: a Paws::Lambda::FunctionConfiguration instance

Creates a new Lambda function. The function metadata is created from the request parameters, and the code for the function is provided by a .zip file in the request body. If the function name already exists, the operation will fail. Note that the function name is case-sensitive.

This operation requires permission for the lambda:CreateFunction action.

    DeleteEventSourceMapping(UUID => Str)

Each argument is described in detail in: Paws::Lambda::DeleteEventSourceMapping

Returns: a Paws::Lambda::EventSourceMappingConfiguration instance

Removes an event source mapping. This means AWS Lambda will no longer invoke the function for events in the associated source.

This operation requires permission for the lambda:DeleteEventSourceMapping action.

    DeleteFunction(FunctionName => Str)

Each argument is described in detail in: Paws::Lambda::DeleteFunction

Returns: nothing

Deletes the specified Lambda function code and configuration.

When you delete a function the associated access policy is also deleted. You will need to delete the event source mappings explicitly.

This operation requires permission for the lambda:DeleteFunction action.

    GetEventSourceMapping(UUID => Str)

Each argument is described in detail in: Paws::Lambda::GetEventSourceMapping

Returns: a Paws::Lambda::EventSourceMappingConfiguration instance

Returns configuration information for the specified event source mapping (see CreateEventSourceMapping).

This operation requires permission for the lambda:GetEventSourceMapping action.

    GetFunction(FunctionName => Str)

Each argument is described in detail in: Paws::Lambda::GetFunction

Returns: a Paws::Lambda::GetFunctionResponse instance

Returns the configuration information of the Lambda function and a presigned URL link to the .zip file you uploaded with CreateFunction so you can download the .zip file. Note that the URL is valid for up to 10 minutes. The configuration information is the same information you provided as parameters when uploading the function.

This operation requires permission for the lambda:GetFunction action.

    GetFunctionConfiguration(FunctionName => Str)

Each argument is described in detail in: Paws::Lambda::GetFunctionConfiguration

Returns: a Paws::Lambda::FunctionConfiguration instance

Returns the configuration information of the Lambda function. This the same information you provided as parameters when uploading the function by using CreateFunction.

This operation requires permission for the lambda:GetFunctionConfiguration operation.

    GetPolicy(FunctionName => Str)

Each argument is described in detail in: Paws::Lambda::GetPolicy

Returns: a Paws::Lambda::GetPolicyResponse instance

Returns the access policy, containing a list of permissions granted via the AddPermission API, associated with the specified bucket.

You need permission for the lambda:GetPolicy action.

    Invoke(FunctionName => Str, [ClientContext => Str, InvocationType => Str, LogType => Str, Payload => Str])

Each argument is described in detail in: Paws::Lambda::Invoke

Returns: a Paws::Lambda::InvocationResponse instance

Invokes a specified Lambda function.

This operation requires permission for the lambda:InvokeFunction action.

    InvokeAsync(FunctionName => Str, InvokeArgs => Str)

Each argument is described in detail in: Paws::Lambda::InvokeAsync

Returns: a Paws::Lambda::InvokeAsyncResponse instance

This API is deprecated. We recommend you use Invoke API (see Invoke).

Submits an invocation request to AWS Lambda. Upon receiving the request, Lambda executes the specified function asynchronously. To see the logs generated by the Lambda function execution, see the CloudWatch logs console.

This operation requires permission for the lambda:InvokeFunction action.

    ListEventSourceMappings([EventSourceArn => Str, FunctionName => Str, Marker => Str, MaxItems => Int])

Each argument is described in detail in: Paws::Lambda::ListEventSourceMappings

Returns: a Paws::Lambda::ListEventSourceMappingsResponse instance

Returns a list of event source mappings you created using the CreateEventSourceMapping (see CreateEventSourceMapping), where you identify a stream as an event source. This list does not include Amazon S3 event sources.

For each mapping, the API returns configuration information. You can optionally specify filters to retrieve specific event source mappings.

This operation requires permission for the lambda:ListEventSourceMappings action.

    ListFunctions([Marker => Str, MaxItems => Int])

Each argument is described in detail in: Paws::Lambda::ListFunctions

Returns: a Paws::Lambda::ListFunctionsResponse instance

Returns a list of your Lambda functions. For each function, the response includes the function configuration information. You must use GetFunction to retrieve the code for your function.

This operation requires permission for the lambda:ListFunctions action.

    RemovePermission(FunctionName => Str, StatementId => Str)

Each argument is described in detail in: Paws::Lambda::RemovePermission

Returns: nothing

You can remove individual permissions from an access policy associated with a Lambda function by providing a Statement ID.

Note that removal of a permission will cause an active event source to lose permission to the function.

You need permission for the lambda:RemovePermission action.

    UpdateEventSourceMapping(UUID => Str, [BatchSize => Int, Enabled => Bool, FunctionName => Str])

Each argument is described in detail in: Paws::Lambda::UpdateEventSourceMapping

Returns: a Paws::Lambda::EventSourceMappingConfiguration instance

You can update an event source mapping. This is useful if you want to change the parameters of the existing mapping without losing your position in the stream. You can change which function will receive the stream records, but to change the stream itself, you must create a new mapping.

This operation requires permission for the lambda:UpdateEventSourceMapping action.

    UpdateFunctionCode(FunctionName => Str, [S3Bucket => Str, S3Key => Str, S3ObjectVersion => Str, ZipFile => Str])

Each argument is described in detail in: Paws::Lambda::UpdateFunctionCode

Returns: a Paws::Lambda::FunctionConfiguration instance

Updates the code for the specified Lambda function. This operation must only be used on an existing Lambda function and cannot be used to update the function configuration.

This operation requires permission for the lambda:UpdateFunctionCode action.

    UpdateFunctionConfiguration(FunctionName => Str, [Description => Str, Handler => Str, MemorySize => Int, Role => Str, Timeout => Int])

Each argument is described in detail in: Paws::Lambda::UpdateFunctionConfiguration

Returns: a Paws::Lambda::FunctionConfiguration instance

Updates the configuration parameters for the specified Lambda function by using the values provided in the request. You provide only the parameters you want to change. This operation must only be used on an existing Lambda function and cannot be used to update the function’s code.

This operation requires permission for the lambda:UpdateFunctionConfiguration action.
