multiclient

Higher throughput client connection pool when transferring large messages (such as downloading files).

Feature

  • Non exclusive, shared connection pool
  • Making full use of the asynchronous communication advantages of each connection
  • Higher throughput when transferring large messages(≥1MB)
  • Preempt more network bandwidth in a shared network environment
  • Load balancing mechanism of traffic level
  • Real-time monitoring of connection status

Usage

import "github.com/henrylee2cn/teleport/v6/mixer/multiclient"

Test
package multiclient_test

import (
	"testing"
	"time"

	tp "github.com/henrylee2cn/teleport/v6"
	"github.com/henrylee2cn/teleport/v6/mixer/multiclient"
)

type Arg struct {
	A int
	B int `param:"<range:1:>"`
}

type P struct{ tp.CallCtx }

func (p *P) Divide(arg *Arg) (int, *tp.Status) {
	return arg.A / arg.B, nil
}

func TestMultiClient(t *testing.T) {
	srv := tp.NewPeer(tp.PeerConfig{
		ListenPort: 9090,
	})
	srv.RouteCall(new(P))
	go srv.ListenAndServe()
	time.Sleep(time.Second)

	cli := multiclient.New(
		tp.NewPeer(tp.PeerConfig{}),
		":9090",
		100,
		time.Second*5,
	)
	go func() {
		for {
			t.Logf("%+v", cli.Stats())
			time.Sleep(time.Millisecond * 500)
		}
	}()
	go func() {
		var result int
		for i := 0; ; i++ {
			stat := cli.Call("/p/divide", &Arg{
				A: i,
				B: 2,
			}, &result).Status()
			if !stat.OK() {
				t.Log(stat)
			} else {
				t.Logf("%d/2=%v", i, result)
			}
			time.Sleep(time.Millisecond * 500)
		}
	}()
	time.Sleep(time.Second * 6)
	cli.Close()
	time.Sleep(time.Second * 3)
}

test command:

go test -v -run=TestMultiClient

Types

type MultiClient

type MultiClient struct {
	// contains filtered or unexported fields
}

MultiClient client session which is has connection pool

func New

func New(peer tp.Peer, addr string, sessMaxQuota int, sessMaxIdleDuration time.Duration, protoFunc ...tp.ProtoFunc) *MultiClient

New creates a client session which is has connection pool.

func (*MultiClient) Addr

func (c *MultiClient) Addr() string

Addr returns the address.

func (*MultiClient) AsyncCall

func (c *MultiClient) AsyncCall(
	uri string,
	arg interface{},
	result interface{},
	callCmdChan chan<- tp.CallCmd,
	setting ...tp.MessageSetting,
) tp.CallCmd

AsyncCall sends a message and receives reply asynchronously. If the arg is []byte or *[]byte type, it can automatically fill in the body codec name.

func (*MultiClient) Call

func (c *MultiClient) Call(uri string, arg interface{}, result interface{}, setting ...tp.MessageSetting) tp.CallCmd

Call sends a message and receives reply. NOTE: If the arg is []byte or *[]byte type, it can automatically fill in the body codec name; If the session is a client role and PeerConfig.RedialTimes>0, it is automatically re-called once after a failure.

func (*MultiClient) Close

func (c *MultiClient) Close()

Close closes the session.

func (*MultiClient) Peer

func (c *MultiClient) Peer() tp.Peer

Peer returns the peer.

func (*MultiClient) Push

func (c *MultiClient) Push(uri string, arg interface{}, setting ...tp.MessageSetting) *tp.Status

Push sends a message, but do not receives reply. NOTE: If the arg is []byte or *[]byte type, it can automatically fill in the body codec name; If the session is a client role and PeerConfig.RedialTimes>0, it is automatically re-called once after a failure.

func (*MultiClient) Stats

func (c *MultiClient) Stats() pool.WorkshopStats

Stats returns the current session pool stats.
