  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](https://docs.aws.amazon.com/lambda/latest/dg/welcome.html) 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](http://aws.amazon.com/tools/).

  For a list of Region-specific endpoints that Lambda supports, see [Lambda endpoints and quotas
  ](https://docs.aws.amazon.com/general/latest/gr/lambda-service.html/) 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](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html)
  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](https://www.amazontrust.com/repository/), 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.](http://aws.amazon.com/certificate-manager/faqs/#certificates)

    * `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.

  Creates a Lambda function.

  To create a function, you need a [deployment package](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html)
  and an [execution role](https://docs.aws.amazon.com/lambda/latest/dg/intro-permission-model.html#lambda-intro-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](https://docs.aws.amazon.com/lambda/latest/dg/lambda-images.html). 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](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html#gettingstarted-package-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, 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](https://docs.aws.amazon.com/lambda/latest/dg/functions-states.html).

  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](https://docs.aws.amazon.com/lambda/latest/dg/lambda-invocation.html).

  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](https://docs.aws.amazon.com/lambda/latest/dg/invocation-sync.html),
  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](https://docs.aws.amazon.com/lambda/latest/dg/monitoring-functions.html) and
  [trace](https://docs.aws.amazon.com/lambda/latest/dg/lambda-x-ray.html).  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](https://docs.aws.amazon.com/lambda/latest/dg/retries-on-errors.html).

  For [asynchronous invocation](https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html),
  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](https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html#dlq).

  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](https://docs.aws.amazon.com/lambda/latest/dg/limits.html), 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](https://docs.aws.amazon.com/IAM/latest/UserGuide/list_awslambda.html)
  action.

  specified age. The default value is infinite (-1). When set to infinite (-1),
  failed records are retried until the record expires

  number of retries. The default value is infinite (-1). When set to infinite
  (-1), failed records are retried until the record expires.
