pool
Pool 用于管理客户端到服务集群之间的连接.
Pool的主要功能:
通用连接池 - Pool for GRPC,RPC,TCP.support RPC timeout.
支持集群 - Connet to Cluster.
动态更新 - Danamic update targets.
Pool runs on Linux, Mac OS X, and Windows.
声明:当前使用随机数策略达到动态负载均衡.
下载
go get -u gopkg.in/flyaways/pool.v1
导入方法
import "gopkg.in/flyaways/pool.v1"
使用示例
package main
import (
"log"
"time"
"gopkg.in/flyaways/pool.v1"
"google.golang.org/grpc"
)
func main() {
options := &pool.Options{
InitTargets: []string{"127.0.0.1:8080"},
InitCap: 5,
MaxCap: 30,
DialTimeout: time.Second * 5,
IdleTimeout: time.Second * 60,
ReadTimeout: time.Second * 5,
WriteTimeout: time.Second * 5,
}
//初始化连接池
p, err := pool.NewGRPCPool(options, grpc.WithInsecure())
if err != nil {
log.Printf("%#v\n", err)
return
}
if p == nil {
log.Printf("p= %#v\n", p)
return
}
defer p.Close()
//动态更新服务地址
//options.Input()
conn, err := p.Get()
if err != nil {
log.Printf("%#v\n", err)
return
}
defer p.Put(conn)
//实现各种业务代码
//conn.DoSomething()
//打印空闲连接数
log.Printf("len=%d\n", p.IdleCount())
}
