package main

	requestsio "github.com/arquivei/arqbeam-requestsio"
)

var (
	pipeline *beam.Pipeline
	version  = "dev"
)

var config struct {
	beamapp.Config
	GCSInputFile string
}

func main() {
	beamapp.Bootstrap(version, &config)
	pipeline = getPipeline(context.Background())
	beamapp.Run(pipeline)
}

type JSONExample struct {
	Data string `json:"data"`
}

func getPipeline(_ context.Context) *beam.Pipeline {
	if pipeline != nil {
		return pipeline
	}

	pipeline := beam.NewPipeline()
	s := pipeline.Root()

	// Read some files with textio default from apache beam go sdk
	readRows := textio.Read(s, config.GCSInputFile)

	jsonData := beam.ParDo(s, func(elm string) JSONExample { return JSONExample{Data: elm} }, readRows)

	// Send each line to endpoint with requestsio from arqbeam-requestsio
	requestsio.Post(s, "localhost:8080", jsonData)

	return pipeline
}
