Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :function_name (required, String) —

  The name or ARN of the Lambda function, version, or alias.

  Name formats

  • Function name – my-function (name-only), my-function:v1 (with alias).

  • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

  • Partial ARN – 123456789012:function:my-function.

  You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

• :statement_id (required, String) —

  A statement identifier that differentiates the statement from others in the same policy.

• :action (required, String) —

  The action that the principal can use on the function. For example, lambda:InvokeFunction or lambda:GetFunction.

• :principal (required, String) —

  The Amazon Web Services service, Amazon Web Services account, IAM user, or IAM role that invokes the function. If you specify a service, use SourceArn or SourceAccount to limit who can invoke the function through that service.

• :source_arn (String) —

  For Amazon Web Services services, the ARN of the Amazon Web Services resource that invokes the function. For example, an Amazon S3 bucket or Amazon SNS topic.

  Note that Lambda configures the comparison using the StringLike operator.

• :source_account (String) —

  For Amazon Web Services service, the ID of the Amazon Web Services account that owns the resource. Use this together with SourceArn to ensure that the specified account owns the resource. It is possible for an Amazon S3 bucket to be deleted by its owner and recreated by another account.

• :event_source_token (String) —

  For Alexa Smart Home functions, a token that the invoker must supply.

• :qualifier (String) —

  Specify a version or alias to add permissions to a published version of the function.

• :revision_id (String) —

  Update the policy only if the revision ID matches the ID that's specified. Use this option to avoid modifying a policy that has changed since you last read it.

• :principal_org_id (String) —

  The identifier for your organization in Organizations. Use this to grant permissions to all the Amazon Web Services accounts under this organization.

• :function_url_auth_type (String) —

  The type of authentication that your function URL uses. Set to AWS_IAM if you want to restrict access to authenticated users only. Set to NONE if you want to bypass IAM authentication to create a public endpoint. For more information, see Security and auth model for Lambda function URLs.

Returns:

• (Types::AddPermissionResponse) —

  Returns a response object which responds to the following methods:

  • #statement => String

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :event_source_arn (String) —

  The Amazon Resource Name (ARN) of the event source.

  • Amazon Kinesis – The ARN of the data stream or a stream consumer.

  • Amazon DynamoDB Streams – The ARN of the stream.

  • Amazon Simple Queue Service – The ARN of the queue.

  • Amazon Managed Streaming for Apache Kafka – The ARN of the cluster or the ARN of the VPC connection (for cross-account event source mappings).

  • Amazon MQ – The ARN of the broker.

  • Amazon DocumentDB – The ARN of the DocumentDB change stream.

• :function_name (required, String) —

  The name or ARN of the Lambda function.

  Name formats

  • Function name – MyFunction.

  • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction.

  • Version or Alias ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD.

  • Partial ARN – 123456789012:function:MyFunction.

  The length constraint applies only to the full ARN. If you specify only the function name, it's limited to 64 characters in length.

• :enabled (Boolean) —

  When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

  Default: True

• :batch_size (Integer) —

  The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

  • Amazon Kinesis – Default 100. Max 10,000.

  • Amazon DynamoDB Streams – Default 100. Max 10,000.

  • Amazon Simple Queue Service – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

  • Amazon Managed Streaming for Apache Kafka – Default 100. Max 10,000.

  • Self-managed Apache Kafka – Default 100. Max 10,000.

  • Amazon MQ (ActiveMQ and RabbitMQ) – Default 100. Max 10,000.

  • DocumentDB – Default 100. Max 10,000.

• :filter_criteria (Types::FilterCriteria) —

  An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

• :maximum_batching_window_in_seconds (Integer) —

  The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

  For Kinesis, DynamoDB, and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

  Related setting: For Kinesis, DynamoDB, and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

• :parallelization_factor (Integer) — default: Kinesis and DynamoDB Streams only —

  The number of batches to process from each shard concurrently.

• :starting_position (String) —

  The position in a stream from which to start reading. Required for Amazon Kinesis and Amazon DynamoDB Stream event sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams, Amazon DocumentDB, Amazon MSK, and self-managed Apache Kafka.

• :starting_position_timestamp (Time, DateTime, Date, Integer, String) —

  With StartingPosition set to AT_TIMESTAMP, the time from which to start reading. StartingPositionTimestamp cannot be in the future.

• :destination_config (Types::DestinationConfig) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Kafka only —

  A configuration object that specifies the destination of an event after Lambda processes it.

• :maximum_record_age_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

  Discard records older than the specified age. The default value is infinite (-1).

• :bisect_batch_on_function_error (Boolean) — default: Kinesis and DynamoDB Streams only —

  If the function returns an error, split the batch in two and retry.

• :maximum_retry_attempts (Integer) — default: Kinesis and DynamoDB Streams only —

  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.

• :tags (Hash<String,String>) —

  A list of tags to apply to the event source mapping.

• :tumbling_window_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

  The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

• :topics (Array<String>) —

  The name of the Kafka topic.

• :queues (Array<String>) — default: MQ —

  The name of the Amazon MQ broker destination queue to consume.

• :source_access_configurations (Array<Types::SourceAccessConfiguration>) —

  An array of authentication protocols or VPC components required to secure your event source.

• :self_managed_event_source (Types::SelfManagedEventSource) —

  The self-managed Apache Kafka cluster to receive records from.

• :function_response_types (Array<String>) — default: Kinesis, DynamoDB Streams, and Amazon SQS —

  A list of current response type enums applied to the event source mapping.

• :amazon_managed_kafka_event_source_config (Types::AmazonManagedKafkaEventSourceConfig) —

  Specific configuration settings for an Amazon Managed Streaming for Apache Kafka (Amazon MSK) event source.

• :self_managed_kafka_event_source_config (Types::SelfManagedKafkaEventSourceConfig) —

  Specific configuration settings for a self-managed Apache Kafka event source.

• :scaling_config (Types::ScalingConfig) — default: Amazon SQS only —

  The scaling configuration for the event source. For more information, see Configuring maximum concurrency for Amazon SQS event sources.

• :document_db_event_source_config (Types::DocumentDBEventSourceConfig) —

  Specific configuration settings for a DocumentDB event source.

• :kms_key_arn (String) —

  The ARN of the Key Management Service (KMS) customer managed key that Lambda uses to encrypt your function's filter criteria. By default, Lambda does not encrypt your filter criteria object. Specify this property to encrypt data using your own customer managed key.

• :metrics_config (Types::EventSourceMappingMetricsConfig) —

  The metrics configuration for your event source. For more information, see Event source mapping metrics.

• :provisioned_poller_config (Types::ProvisionedPollerConfig) — default: Amazon MSK and self-managed Apache Kafka only —

  The provisioned mode configuration for the event source. For more information, see provisioned mode.

Returns:

• (Types::EventSourceMappingConfiguration) —

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :function_name (required, String) —

  The name or ARN of the Lambda function.

  Name formats

  • Function name – my-function.

  • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

  • Partial ARN – 123456789012:function:my-function.

  The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

• :runtime (String) —

  The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image.

  The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation.

  For a list of all currently supported runtimes, see Supported runtimes.

• :role (required, String) —

  The Amazon Resource Name (ARN) of the function's execution role.

• :handler (String) —

  The name of the method within your code that Lambda calls to run your function. Handler is required if the deployment package is a .zip file archive. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see Lambda programming model.

• :code (required, Types::FunctionCode) —

  The code for the function.

• :description (String) —

  A description of the function.

• :timeout (Integer) —

  The amount of time (in seconds) that Lambda allows a function to run before stopping it. The default is 3 seconds. The maximum allowed value is 900 seconds. For more information, see Lambda execution environment.

• :memory_size (Integer) —

  The amount of memory available to the function at runtime. Increasing the function memory also increases its CPU allocation. The default value is 128 MB. The value can be any multiple of 1 MB.

• :publish (Boolean) —

  Set to true to publish the first version of the function during creation.

• :vpc_config (Types::VpcConfig) —

  For network connectivity to Amazon Web Services resources in a VPC, specify a list of security groups and subnets in the VPC. When you connect a function to a VPC, it can access resources and the internet only through that VPC. For more information, see Configuring a Lambda function to access resources in a VPC.

• :package_type (String) —

  The type of deployment package. Set to Image for container image and set to Zip for .zip file archive.

• :dead_letter_config (Types::DeadLetterConfig) —

  A dead-letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead-letter queues.

• :environment (Types::Environment) —

  Environment variables that are accessible from function code during execution.

• :kms_key_arn (String) —

  The ARN of the Key Management Service (KMS) customer managed key that's used to encrypt the following resources:

  • The function's environment variables.

  • The function's Lambda SnapStart snapshots.

  • When used with SourceKMSKeyArn, the unzipped version of the .zip deployment package that's used for function invocations. For more information, see Specifying a customer managed key for Lambda.

  • The optimized version of the container image that's used for function invocations. Note that this is not the same key that's used to protect your container image in the Amazon Elastic Container Registry (Amazon ECR). For more information, see Function lifecycle.

  If you don't provide a customer managed key, Lambda uses an Amazon Web Services owned key or an Amazon Web Services managed key.

• :tracing_config (Types::TracingConfig) —

  Set Mode to Active to sample and trace a subset of incoming requests with X-Ray.

• :tags (Hash<String,String>) —

  A list of tags to apply to the function.

• :layers (Array<String>) —

  A list of function layers to add to the function's execution environment. Specify each layer by its ARN, including the version.

• :file_system_configs (Array<Types::FileSystemConfig>) —

  Connection settings for an Amazon EFS file system.

• :image_config (Types::ImageConfig) —

  Container image configuration values that override the values in the container image Dockerfile.

• :code_signing_config_arn (String) —

  To enable code signing for this function, specify the ARN of a code-signing configuration. A code-signing configuration includes a set of signing profiles, which define the trusted publishers for this function.

• :architectures (Array<String>) —

  The instruction set architecture that the function supports. Enter a string array with one of the valid values (arm64 or x86_64). The default value is x86_64.

• :ephemeral_storage (Types::EphemeralStorage) —

  The size of the function's /tmp directory in MB. The default value is 512, but can be any whole number between 512 and 10,240 MB. For more information, see Configuring ephemeral storage (console).

• :snap_start (Types::SnapStart) —

  The function's SnapStart setting.

• :logging_config (Types::LoggingConfig) —

  The function's Amazon CloudWatch Logs configuration settings.
