Description

Lambdas will be significantly faster (less expensive) and simpler (no more routing or retries in lambda code) with the addition of Destinations for Asynchronous Invocations.

New or Affected Resource(s)

• aws_lambda_function
• aws_lambda_event_destination_mapping (new)

Potential Terraform Configuration

resource "aws_lambda_function" "this" {
    ...
    event_invoke_config {
        maximum_retry_attempts = "..."
        maximum_event_age_in_seconds = "..."
    }
}

resource "aws_lambda_destination" "this" {
    function_name = "..."
    destination_config = {
        on_success = {
            destination = "..."
        }
        on_failure = {
            destination = "..."
        }
    }
}

I'll pick this one up since it is similar in configuration and testing to the new Lambda Provisioned Concurrency configuration. Since the API refers to these as "FunctionEventInvokeConfig", we'll probably stick with an admittedly uglier aws_lambda_function_event_invoke_config resource naming. We'll also want to introduce this solely as a separate resource to prevent multiple Terraform resources from being able to manage the same underlying infrastructure configuration.
