type Job

type Job interface {
	// JobName returns the name of the job.
	JobName() string

	GetDoneCh() <-chan struct{}
}

Job is a runnable interface to queue jobs on a WorkerPool

type ProcessFunc

type ProcessFunc func(key, name, namespace string) (bool, error)

type WorkerPool

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

func (*WorkerPool) AddJob

func (wp *WorkerPool) AddJob(job Job) <-chan struct{}

AddJob posts the job on a worker queue Uses Hash underneath to choose worker to post the job to

func (*WorkerPool) AddJobRoundRobin

func (wp *WorkerPool) AddJobRoundRobin(jobs Job)

AddJobRoundRobin adds a job in round robin to the queues Concurrent calls to AddJobRoundRobin are thread safe and fair between each other

func (*WorkerPool) GetWorkerNumber

func (wp *WorkerPool) GetWorkerNumber() int

GetWorkerNumber get number of queues/workers

func (*WorkerPool) Stop
