Overview

An API client for LambdaPreview. To construct a client, you need to configure a :region and :credentials.

client = Aws::LambdaPreview::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::SharedCredentials - Used for loading credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]

    • adaptive - An experimental retry mode that includes all the functionality of standard mode along with automatic client side throttling. This is a provisional mode that may change behavior in the future.

  • :secret_access_key (String)
  • :session_token (String)
  • :stub_responses (Boolean) — default: false —

    Causes the client to return stubbed responses. By default fake responses are generated and returned. You can specify the response data to return or errors to raise by calling ClientStubs#stub_responses. See ClientStubs for more information.

Instance Method Details

#add_event_source(params = {}) ⇒ Types::EventSourceConfiguration

Identifies a stream as an event source for an AWS Lambda function. It can be either an Amazon Kinesis stream or a 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 an AWS Lambda function is called the event source mapping. You provide the configuration information (for example, which stream to read from and which AWS Lambda function to invoke) for the event source mapping in the request body.

Each event source, such as a Kinesis stream, can only be associated with one AWS Lambda function. If you call AddEventSource for an event source that is already mapped to another AWS Lambda function, the existing mapping is updated to call the new function instead of the old one.

This operation requires permission for the iam:PassRole action for the IAM role. It also requires permission for the lambda:AddEventSource action.

Examples:

Request syntax with placeholder values


resp = client.add_event_source({
  event_source: "String", # required
  function_name: "FunctionName", # required
  role: "RoleArn", # required
  batch_size: 1,
  parameters: {
    "String" => "String",
  },
})

Response structure

resp.function_name #=> String
resp.parameters #=> Hash
resp.parameters["String"] #=> String
resp.role #=> String
resp.last_modified #=> Time
resp.is_active #=> Boolean
resp.status #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :event_source (required, String) —

    The Amazon Resource Name (ARN) of the Amazon Kinesis stream that is the event source. Any record added to this stream causes AWS Lambda to invoke your Lambda function. AWS Lambda POSTs the Amazon Kinesis event, containing records, to your Lambda function as JSON.

  • :function_name (required, String) —

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

  • :role (required, String) —

    The ARN of the IAM role (invocation role) that AWS Lambda can assume to read from the stream and invoke the function.

  • :batch_size (Integer) —

    The largest number of records that AWS Lambda will give to your function in a single event. The default is 100 records.

  • :parameters (Hash<String,String>) —

    A map (key-value pairs) defining the configuration for AWS Lambda to use when reading the event source. Currently, AWS Lambda supports only the InitialPositionInStream key. The valid values are: "TRIM_HORIZON" and "LATEST". The default value is "TRIM_HORIZON". For more information, go to ShardIteratorType in the Amazon Kinesis Service API Reference.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name of the Lambda function.

  • :role (String) —

    The Amazon Resource Name (ARN) of the IAM role that Lambda will assume when it executes your function.

  • :handler (String) —

    The function that Lambda calls to begin executing your function. For Node.js, it is the module-name.export value in your function.

  • :description (String) —

    A short user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit.

  • :timeout (Integer) —

    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.

  • :memory_size (Integer) —

    The amount of memory, in MB, your Lambda function is given. Lambda uses this memory size to infer the amount of CPU allocated to your function. Your function use-case determines your CPU and memory requirements. For example, a database operation might need less memory compared to an image processing function. The default value is 128 MB. The value must be a multiple of 64 MB.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name you want to assign to the function you are uploading. The function names appear in the console and are returned in the ListFunctions API. Function names are used to specify functions to other AWS Lambda APIs, such as InvokeAsync.

  • :function_zip (required, String, IO) —

    A .zip file containing your packaged source code. For more information about creating a .zip file, go to AWS LambdaL How it Works in the AWS Lambda Developer Guide.

  • :runtime (required, String) —

    The runtime environment for the Lambda function you are uploading. Currently, Lambda supports only "nodejs" as the runtime.

  • :role (required, String) —

    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.

  • :handler (required, String) —

    The function that Lambda calls to begin execution. For Node.js, it is the module-name.export value in your function.

  • :mode (required, String) —

    How the Lambda function will be invoked. Lambda supports only the "event" mode.

  • :description (String) —

    A short, user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit.

  • :timeout (Integer) —

    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.

  • :memory_size (Integer) —

    The amount of memory, in MB, your Lambda function is given. Lambda uses this memory size to infer the amount of CPU allocated to your function. Your function use-case determines your CPU and memory requirements. For example, database operation might need less memory compared to image processing function. The default value is 128 MB. The value must be a multiple of 64 MB.
