How to specify AWS aurora DB as serverless using terraform

AWS

Hi All,

I am very new into AWS and Terraform.

Here am trying to create an Aurora (PostgreSQL compatible) database in AWS using Terraform code.

I could be able to create a database using a basic terraform script but need to create a serverless Aurora database. I cannot find any option or parameter in Terraform Docs, to mark the database as serverless.

What I have tried:

I have created a database using simple Terraform script as given below:

provider "aws" {
  profile = "default"
  region = "us-west-2"
  shared_credentials_file = "/Users/firstname.lastname/.aws/creds"
}

resource "aws_rds_cluster" "postgresql" {
  cluster_identifier      = "aurora-cluster"
  db_subnet_group_name    = "<subnet group="" name="">"
  engine                  = "aurora-postgresql"
  availability_zones      = ["us-west-2a", "us-west-2b", "us-west-2c"]
  database_name           = "myTestdb"
  master_username         = "********"
  master_password         = "********"
  backup_retention_period = 5
  preferred_backup_window = "07:00-09:00"
}
