Question

需要：

将某些参数保存到数据库，如请求参考。
超快速渲染响应。

控制器示例：

---
- name: Base-AMI | Create a Base-AMI
  hosts: localhost
  connection: local
  gather_facts: False
  vars_files:
      - vars.yml
  tasks:
- name: Launch instance
  ec2:
     key_name: "{{ key_pair }}"
     group: "{{ security_group }}"
     instance_type: "{{ instance_type }}"
     image: "{{ image }}"
     wait: true
     region: "{{ region }}"
     vpc_subnet_id: "{{ vpc_subnet_id }}"
     assign_public_ip: yes
     instance_tags:
       Type: Base-AMI
  register: ec2

- name: Add new instance to host group
  add_host: hostname={{ item.public_ip }} groupname=launched ansible_ssh_user=ubuntu ansible_ssh_private_key_file=~/.ssh/{{ key_pair }}.pem
  with_items: ec2.instances

- name: Wait for SSH to come up
  wait_for: host={{ item.public_dns_name }} port=22 delay=60 timeout=320 state=started
  with_items: ec2.instances

- name: Configure instance(s)
  hosts: launched
  sudo: True
  gather_facts: True
  roles:
    - common
    - rubyserver

- name: Base-AMI | AMI Creation
  hosts: localhost
  connection: local
  gather_facts: False
  tasks:

- name: Launch instance
  ec2_ami:
    instance_id: "{{ item.id }}"
    wait: yes
    name: Base-AMI
    tags:
      Date: "{{ ansible_date_time.iso8601 }}"
    device_mapping:
        - device_name: /dev/sda1
          size: 10
          delete_on_termination: true
          volume_type: gp2
  register: instance

当用户请求此操作时，它不会超快，因为它首先需要写入数据库。

以后可以写入数据库吗？

我曾尝试设置后台作业但速度也很慢。存储此信息的最快方法是什么？在文件中？

Rails如何在保存到数据库时快速呈现页面？
