### Cache 分布式方案-Getway
![getway方案](https://gitee.com/timedb/img/raw/master/images/getway方案.svg)
1. single 集群分布式方案中,使用 getway 方向代理客户端的 grpc 请求, 通过 hash 环实现 分布式。
2. 集群模式中, 通过主从来 实现 cache 的备份问题,提高容灾性。

### 构建工具文档
#### dcgen
1. 根据结构体接口模板生成 proto 文件
2. 迁移 proto 到 pkg/proto 下
3. 更新结构体常量
>PS : 开发一个 storage 的新接口时一般有以下步骤
>1. 修改 storage 接口配置文件
>2. make dcgen
>3. 修改生成的 proto 文件
>4. make dcgen
>5. 添加 storage 的操作接口
#### build-storage
编译并且生成 /bin/storage
#### build-gateway
编译并且生成 /bin/gateway
#### install
1. 安装项目,需要 sudo
#### storage
根据配置文件启动 storage
#### gateway
根据配置文件启动 gateway
#### init-conf
根据配置文件文档初始化配置文件到 /etc/wheat-cache/wheat-cache.yaml

Init() // 初始化
Exec(interface{}) (interface{}, error) // 处理用户发送事件
Name() string // 获取中间件名称
Describe() string // 描述

### 结构体开发文档
#### 基础结构体开发
- 基础结构体放到 /pkg/structure。
- 每个结构 类型都以 x 结尾,如 listx stringx。
- 在 pkg/structure/define.go 文件中添加对应结构体的接口,主要为 了保证项目可以扩展线程安全结构体, 以及结构体接口的实现, 目前 lru 采用 single 模式, 可以只开发 single 的结构体,如 stringxSingle。
- 请在结构体包中 补充单元测试。
#### 目前实现结构体接口说明
> ps: 所有的详细用法都可以查看单元测试文件。
```go
// stringx
type StringXInterface interface {
KeyBaseInterface
// 重新设置一个 值
Set(string) (string, UpdateLength)
// 获取值的 string 形式
Get() string
// 值自动增加 一个值,只对 float 和 string 有效
Add(int32) (string, error)
// 值自动增加 减少值,只对 float 和 string 有效
Reduce(int32) (string, error)
// 使用位图类型
Setbit(int32, bool) UpdateLength
Getbit(int32) (bool, error)
// 获取字符串的切片
Getrange(start, end int32) (string, error)
GetLength() int
}
// listx
type ListXInterface interface {
KeyBaseInterface
LPush(...string) UpdateLength
RPush(...string) UpdateLength
LPop(int) ([]string, UpdateLength)
RPop(int) ([]string, UpdateLength)
Index(int) (string, error)
// 插入一组数据, bool 类型表示是否右插尾插false 时采用左插(头插)
Insert(int, bool, ...string) (UpdateLength, error)
Length() int
// 切片, O(n)复杂度
Slice(start, end int) (UpdateLength, error)
}
```
### structure.Value 类型
- 结构体的数据区域全部使用 structure.Value 类型存储。
- structure.Value 主要实现了 sting, int64, float64 的存储接口。
- structure.Value 非常容易计算内存占用。
- structure.UpdateLength 指的是在进行某一个操作以后,内存大小的变化。
- 为了保证 lru 的存储效率lru 不会去遍历全部的 key 来重新计算大小,而是根据 UpdateLength 来动态更新 lru 的大小,具体实现在 dao 中。
- structure.Value 类型的使用方法可以在 pkg/structure/value_test.go 中获取。

### 快速进行 storage 开发
#### 开发环境
- ubuntu18, 可以使用 wsl
- go1.15+, python3
- jinja2
- go mod
- protobuf 3.17.3
- protoc-gen-go v1.26.0
#### storage 执行流程
![](../_icon/storage-dao.svg)
#### 分层,简介
```sh
.
├── cmd # storage 启动函数
│ └── root.go
├── dao # 实际处理层,接口实现全部再 dao 层里实现
│ ├── dao.go
│ ├── dao_test.go
│ ├── interface.gen.go
│ ├── listx.go # listx 相关功能
│ └── stringx.go
├── main.go
├── service # 接口层,由 gen-service 自动生成
│ ├── define.go
│ ├── single.go
│ └── single_service.gen.go
└── temp # 开发模板层
├── const.gen.go
├── const.template
├── dao.template
├── service.template
└── tem.yaml
```
#### 快速开发接口
> [快速开发视频 blibli](https://www.bilibili.com/video/BV1HL4y1v7ps)
1. 修改 temp/tem.yaml 文件,添加新接口
2. 在项目根目录执行 `make dcgen` 生成 proto 原始结构
3. 修改对应新添加接口的 proto 文件,再次执行 `make dcgen` 完成 proto 迁移
4. 执行 `make gen-service` 生成 dao 接口
5. 完成 新 dao 层接口, 根据需要添加单元测试。
6. 使用 make install 编译并且安装项目
