benchmark

How can we create a configuration for gobench with -benchmem – IDEs Support (IntelliJ Platform) | JetBrains

本机进行watermill-benchmark

1. 使用 apifox 自动化测试上报固定数量的消息

2. 启动watermill-pub/sub的 benchmark 函数

   func BenchmarkPubSub(b *testing.B) {
   	for i := 0; i < 1; i++ {
   		b.StopTimer()
   		logger := watermillzap.NewLogger(log.Logger)
   		publisher, subscriber := consumer.NewPubSub(logger)
   		router, err := message.NewRouter(message.RouterConfig{}, logger)
   		if err != nil {
   			log.Logger.Fatal("create router error", zap.Error(err))
   		}
   
   		router.AddPlugin(plugin.SignalsHandler)
   		router.AddMiddleware(
   			middleware.InstantAck,
   			middleware.Recoverer,
   		)
   
   		router.AddMiddleware(consumer.UnpackKafkaMessage, consumer.InitPerformanceEvent, consumer.AnalyzeEvent)
   		router.AddHandler("crash", "to_analyzer__0.PERF_CRASH", subscriber, "solar-dev.PERF_CRASH", publisher, consumer.CrashHandler)
   		router.AddHandler("lag", "to_analyzer__0.PERF_LAG", subscriber, "solar-dev.PERF_LAG", publisher, consumer.LagHandler)
   		go func() {
   			for {
   				if kafka.PublishCount >= 10000 && router.IsRunning() {
   					err = router.Close()
   					fmt.Printf("router close err:%v\n", err)
   					break
   				}
   			}
   		}()
   		b.StartTimer()
   		if err = router.Run(context.Background()); err != nil {
   			log.Logger.Error("router run error", zap.Error(err))
   		}
   	}
   }

单 topic

双 topic

add publisher send message trace & log logic

1. 在 handler 了中将 data 用 message 的 Context 传递下来
2. 获取 WriteKafkaSpan 和 RootSpan 手动 End
3. 打日志

profile/internal/watermill/pubsub/consumer_stage.go

// crashHandler
// @Description
// @Author xzx 2023-08-12 15:09:15
// @Param msg
// @Return []*message.Message
// @Return error
func crashHandler(msg *message.Message) ([]*message.Message, error) {
	data := GetDataFromMsg(msg)

	writeKafkaCtx, span := otelclient.ConsumerTracer.Start(data.RootSpanCtx, "crashHandler",
		trace.WithSpanKind(trace.SpanKindProducer))
	setSpanAttributes(span, data)
	data.WriteKafkaSpan = span
	toWriteBytes, contextErr := json.Marshal(data.Event)
	if contextErr != nil {
		data.Status = state.StatusUnmarshalError
		handlerErr(writeKafkaCtx, "marshal error", contextErr)
		data.WriteKafkaSpan.End()
		data.RootSpan.End()
		return nil, contextErr
	}

	msg = message.NewMessage(data.Event.BackendID, toWriteBytes)
	msg.Metadata.Set(watermillkafka.HeaderKey, data.Event.ID)
	log.Logger.Info("[4-crashHandler]", zap.String("topic", connector.GetTopic(data.Event.Category)), zap.String("id", data.Event.ID), zap.String("msg", string(toWriteBytes)))

	SetDataInMsg(msg, data)
	return message.Messages{msg}, nil
}
