    • getDeadLetterQueue

      @Stability(Stable) @Nullable default IQueue getDeadLetterQueue()
      The SQS queue to use if DLQ is enabled.

      If SNS topic is desired, specify deadLetterTopic property instead.

      Default: - SQS queue with 14 day retention period if `deadLetterQueueEnabled` is `true`

    • getDeadLetterQueueEnabled

      @Stability(Stable) @Nullable default Boolean getDeadLetterQueueEnabled()
      Enabled DLQ.

      If deadLetterQueue is undefined, an SQS queue with default options will be defined for your Function.

    • getDeadLetterTopic

      @Stability(Stable) @Nullable default ITopic getDeadLetterTopic()
      The SNS topic to use as a DLQ.

      Note that if deadLetterQueueEnabled is set to true, an SQS queue will be created rather than an SNS topic. Using an SNS topic as a DLQ requires this property to be set explicitly.

      Default: - no SNS topic

    • getDescription

      @Stability(Stable) @Nullable default String getDescription()
      A description of the function.

      Default: - No description.

    • getFunctionName

      @Stability(Stable) @Nullable default String getFunctionName()
      A name for the function.

      Default: - AWS CloudFormation generates a unique physical ID and uses that ID for the function's name. For more information, see Name Type.

    • getInitialPolicy

      @Stability(Stable) @Nullable default List<PolicyStatement> getInitialPolicy()
      Initial policy statements to add to the created Lambda Role.

      You can call addToRolePolicy to the created lambda to add statements post creation.

      Default: - No policy statements are added to the created Lambda role.

    • getInsightsVersion

      @Stability(Stable) @Nullable default LambdaInsightsVersion getInsightsVersion()
      Specify the version of CloudWatch Lambda insights to use for monitoring.

      Default: - No Lambda Insights

      See Also:

    • getLayers

      @Stability(Stable) @Nullable default List<ILayerVersion> getLayers()
      A list of layers to add to the function's execution environment.

      You can configure your Lambda function to pull in additional code during initialization in the form of layers. Layers are packages of libraries or other dependencies that can be used by multiple functions.

      Default: - No layers.

    • getLogRetention

      @Stability(Stable) @Nullable default RetentionDays getLogRetention()
      The number of days log events are kept in CloudWatch Logs.

      When updating this property, unsetting it doesn't remove the log retention policy. To remove the retention policy, set the value to INFINITE.

      Default: logs.RetentionDays.INFINITE

    • getLogRetentionRetryOptions

      @Stability(Stable) @Nullable default LogRetentionRetryOptions getLogRetentionRetryOptions()
      When log retention is specified, a custom resource attempts to create the CloudWatch log group.

      These options control the retry policy when interacting with CloudWatch APIs.

      Default: - Default AWS SDK retry options.

    • getLogRetentionRole

      @Stability(Stable) @Nullable default IRole getLogRetentionRole()
      The IAM role for the Lambda function associated with the custom resource that sets the retention policy.

    • getMemorySize

      @Stability(Stable) @Nullable default Number getMemorySize()
      The amount of memory, in MB, that is allocated to your Lambda function.

      Lambda uses this value to proportionally allocate the amount of CPU power. For more information, see Resource Model in the AWS Lambda Developer Guide.

      Default: 128

    • getProfiling

      @Stability(Stable) @Nullable default Boolean getProfiling()

      Profiling Group.

      Default: - A new profiling group will be created if `profiling` is set.

      See Also:

    • getReservedConcurrentExecutions

      @Stability(Stable) @Nullable default Number getReservedConcurrentExecutions()
      The maximum of concurrent executions you want to reserve for the function.

      Default: - No specific limit - account limit.

      See Also:

    • getRole

      @Stability(Stable) @Nullable default IRole getRole()
      Lambda execution role.

      This is the role that will be assumed by the function upon execution. It controls the permissions that the function will have. The Role must be assumable by the 'lambda.amazonaws.com' service principal.

      The default Role automatically has permissions granted for Lambda execution. If you provide a Role, you must add the relevant AWS managed policies yourself.

      The relevant managed policies are "service-role/AWSLambdaBasicExecutionRole" and "service-role/AWSLambdaVPCAccessExecutionRole".

      Default: - A unique role will be generated for this lambda function. Both supplied and generated roles can always be changed by calling `addToRolePolicy`.

    • getSecurityGroup

      @Stability(Deprecated) @Deprecated @Nullable default ISecurityGroup getSecurityGroup()
      Deprecated.
      • This property is deprecated, use securityGroups instead
      (deprecated) What security group to associate with the Lambda's network interfaces. This property is being deprecated, consider using securityGroups instead.

      Only used if 'vpc' is supplied.

      Use securityGroups property instead. Function constructor will throw an error if both are specified.

      Default: - If the function is placed within a VPC and a security group is not specified, either by this or securityGroups prop, a dedicated security group will be created for this function.

    • getSecurityGroups

      @Stability(Stable) @Nullable default List<ISecurityGroup> getSecurityGroups()
      The list of security groups to associate with the Lambda's network interfaces.

      Only used if 'vpc' is supplied.

      Default: - If the function is placed within a VPC and a security group is not specified, either by this or securityGroup prop, a dedicated security group will be created for this function.

    • getTimeout

      @Stability(Stable) @Nullable default Duration getTimeout()
      The function execution time (in seconds) after which Lambda terminates the function.

      Because the execution time affects cost, set this value based on the function's expected execution time.

      Default: Duration.seconds(3)

    • getTracing

      @Stability(Stable) @Nullable default Tracing getTracing()
      Enable AWS X-Ray Tracing for Lambda Function.

      Default: Tracing.Disabled

    • getVpc

      VPC network to place Lambda network interfaces.

      Specify this if the Lambda function needs to access resources in a VPC.

      Default: - Function is not placed within a VPC.

    • getVpcSubnets

      @Stability(Stable) @Nullable default SubnetSelection getVpcSubnets()
      Where to place the network interfaces within the VPC.

      Only used if 'vpc' is supplied. Note: internet access for Lambdas requires a NAT gateway, so picking Public subnets is not allowed.

      Default: - the Vpc default strategy if not specified

    • builder

      @Stability(Stable) static FunctionOptions.Builder builder()
      Returns:
      a FunctionOptions.Builder of FunctionOptions
