Package consistent provides a consistent hashing function. Consistent hashing is often used to distribute requests to a changing set of servers. For example, say you have some cache servers cacheA, cacheB, and cacheC. You want to decide which cache server to use to look up information on a user. You could use a typical hash table and hash the user id to one of cacheA, cacheB, or cacheC. But with a typical hash table, if you add or remove a server, almost all keys will get remapped to different results, which basically could bring your service to a grinding halt while the caches get rebuilt. With a consistent hash, adding or removing a server drastically reduces the number of keys that get remapped.

##About

server-nado

一个数据库ORM.

Please go to http://github.com/server-nado/orm !

代码已经转移到 http://github.com/server-nado/orm !

How to use?

Insert

go get github.com/server-nado/orm

Super database

sqlite3 "github.com/mattn/go-sqlite3" mysql "github.com/go-sql-driver/mysql" postgree "github.com/lib/pq"

##数据库Model 建立方法

//引用模块
import "github.com/ablegao/orm"

//mysql 驱动
import _ "github.com/go-sql-driver/mysql"

//建立连接 
// 参数分别为 名称 , 驱动, 连接字符串
// 注:必须包含一个default 连接, 作为默认连接。
orm.NewDatabase("default" , "mysql" , "user:passwd@ip/database?charset=utf8&parseTime=true")


//建立一个数据模型。 
type UserInfo struct**** {
	orm.Object
	Id int64 `field:"id" auto:"true" index:"pk"`
	Name string `field:"username"`
	Passwd string `field:"password"`
}

##新增 CacheModel 模型, 支持分布式redis作为数据库缓存。

import "github.com/ablegao/orm"
import _ "github.com/go-sql-driver/mysql"

type userB struct {
	CacheModule
	Uid     int64  `field:"Id" index:"pk" cache:"user" `
	Alias   string `field:"Alias"`
	Money int64  `field:"money"	`
}

func main(){
	orm.CacheConsistent.Add("127.0.0.1:6379")  //添加多个redis服务器
	orm.SetCachePrefix("nado") //默认nado .  将作为redis key 的前缀
	NewDatabase("default", "mysql", "happy:passwd@tcp(127.0.0.1:3306)/mydatabase?charset=utf8&parseTime=true")


	b := new(userB)
	b.Uid = 10000
	err:=b.Objects(b).One()
	if err!= nil {
		panic(err)
	}
	fmt.Println(b.Uid ,b.Alias ,b.Money)

	b.Incrby("Money" , 100)
	fmt.Println(b.Money)
	b.Save() //不执行不会保存到数据库 只会修改redis数据。
