-# 开始使用
-
-## 配置
-
-创建项目成功后，进入项目中的configs目录，mysql.toml，我们可以看到：
-
-```toml
-[demo]
-	addr = "127.0.0.1:3306"
-	dsn = "{user}:{password}@tcp(127.0.0.1:3306)/{database}?timeout=1s&readTimeout=1s&writeTimeout=1s&parseTime=true&loc=Local&charset=utf8mb4,utf8"
-	readDSN = ["{user}:{password}@tcp(127.0.0.2:3306)/{database}?timeout=1s&readTimeout=1s&writeTimeout=1s&parseTime=true&loc=Local&charset=utf8mb4,utf8","{user}:{password}@tcp(127.0.0.3:3306)/{database}?timeout=1s&readTimeout=1s&writeTimeout=1s&parseTime=true&loc=Local&charset=utf8,utf8mb4"]
-	active = 20
-	idle = 10
-	idleTimeout ="4h"
-	queryTimeout = "200ms"
-	execTimeout = "300ms"
-	tranTimeout = "400ms"
-```
-
-在该配置文件中我们可以配置mysql的读和写的dsn、连接地址addr、连接池的闲置连接数idle、最大连接数active以及各类超时。
-
-如果配置了readDSN，在进行读操作的时候会优先使用readDSN的连接。
-
-## 初始化
-
-进入项目的internal/dao目录，打开db.go，其中：
-
-```go
-var cfg struct {
-    Client *sql.Config
-}
-checkErr(paladin.Get("db.toml").UnmarshalTOML(&dc))
-```
-使用paladin配置管理工具将上文中的db.toml中的配置解析为我们需要使用db的相关配置。

-# Kratos
-
-Kratos是bilibili开源的一套Go微服务框架，包含大量微服务相关框架及工具。  
-
-### Goals
-
-我们致力于提供完整的微服务研发体验，整合相关框架及工具后，微服务治理相关部分可对整体业务开发周期无感，从而更加聚焦于业务交付。对每位开发者而言，整套Kratos框架也是不错的学习仓库，可以了解和参考到bilibili在微服务方面的技术积累和经验。
-
-### Principles
-
-* 简单：不过度设计，代码平实简单
-* 通用：通用业务开发所需要的基础库的功能
-* 高效：提高业务迭代的效率
-* 稳定：基础库可测试性高，覆盖率高，有线上实践安全可靠
-* 健壮：通过良好的基础库设计，减少错用
-* 高性能：性能高，但不特定为了性能做hack优化，引入unsafe
-* 扩展性：良好的接口设计，来扩展实现，或者通过新增基础库目录来扩展功能
-* 容错性：为失败设计，大量引入对SRE的理解，鲁棒性高
-* 工具链：包含大量工具链，比如cache代码生成，lint工具等等
-
-### Features
-* HTTP Blademaster：核心基于[gin](https://github.com/gin-gonic/gin)进行模块化设计，简单易用、核心足够轻量；
-* GRPC Warden：基于官方gRPC开发，集成[discovery](https://github.com/bilibili/discovery)服务发现，并融合P2C负载均衡；

 `blademaster`由几个非常精简的内部模块组成。其中`Router`用于根据请求的路径分发请求，`Context`包含了一个完整的请求信息，`Handler`则负责处理传入的`Context`，`Handlers`为一个列表，一个串一个地执行。  
 所有的`middlerware`均以`Handler`的形式存在，这样可以保证`blademaster`自身足够精简且扩展性足够强。

 `blademaster`处理请求的模式非常简单，大部分的逻辑都被封装在了各种`Handler`中。一般而言，业务逻辑作为最后一个`Handler`。

+如果配置了readDSN，在进行读操作的时候会优先使用readDSN的连接。

 在自适应限流保护中，采集到的指标的时效性非常强，系统只需要采集最近一小段时间内的 qps、rt 即可，对于较老的数据，会自动丢弃。为了实现这个效果，kratos 使用了滑动窗口来保存采样数据。

 如上图，展示了一个具有两个桶（bucket）的滑动窗口（rolling window）。整个滑动窗口用来保存最近 1s 的采样数据，每个小的桶用来保存 500ms 的采样数据。
 当时间流动之后，过期的桶会自动被新桶的数据覆盖掉，在图中，在 1000-1500ms 时，bucket 1 的数据因为过期而被丢弃，之后 bucket 3 的数据填到了窗口的头部。

 左测是没有限流的压测效果，右侧是带限流的压测效果。
 可以看到，没有限流的场景里，系统在 700qps 时开始抖动，在 1k qps 时被拖垮，几乎没有新的请求能被放行，然而在使用限流之后，系统请求能够稳定在 600 qps 左右，rt 没有暴增，服务也没有被打垮，可见，限流有效的保护了服务。

 ## 注意
 因为启动mysql容器较为缓慢，健康检测的机制会重试3次，每次暂留5秒钟，基本在10s内mysql就能从creating到服务正常启动！
-
 当然你也可以在使用 testcli 时加上 --nodown，使其不用每次跑都新建容器，只在第一次跑的时候会初始化容器，后面都进行复用，这样速度会快很多。
