Variables

var WorkQueue = make(chan LogRequest, LoggerWorkerQueueSize)

A buffered channel that we can send work requests on.

Functions

	inferenceService string, namespace string, endpoint string, component string, next http.Handler) http.Handler

Types

type LogRequest

type LogRequest struct {
	Url              *url.URL
	Bytes            *[]byte
	ContentType      string
	ReqType          string
	Id               string
	SourceUri        *url.URL
	InferenceService string
	Namespace        string
	Component        string
	Endpoint         string
}

type LoggerHandler

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

func (*LoggerHandler) ServeHTTP

func (eh *LoggerHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)

call svc and add send request/responses to logUrl

type Worker

type Worker struct {
	Log         *zap.SugaredLogger
	ID          int
	Work        chan LogRequest
	WorkerQueue chan chan LogRequest
	QuitChan    chan bool
	CeCtx       context.Context
}

func NewWorker

func NewWorker(id int, workerQueue chan chan LogRequest, logger *zap.SugaredLogger) Worker

NewWorker creates, and returns a new Worker object. Its only argument is a channel that the worker can add itself to whenever it is done its work.

func (*Worker) Start

func (w *Worker) Start()

This function "starts" the worker by starting a goroutine, that is an infinite "for-select" loop.

func (*Worker) Stop

func (w *Worker) Stop()

Stop tells the worker to stop listening for work requests.

Note that the worker will only stop *after* it has finished its work.
