type BacklogPool ¶

type BacklogPool interface {
	ExecutionPool
	EnqueueBacklog(enqueueCtx context.Context, t ExecFunc, arg interface{}, out chan interface{}) error
}

BacklogPool supports all the ExecutionPool functions plus few more that tests the pending tasks.

BacklogPool은 모든 ExecutionPool 기능과 pending task를 테스트하는 몇 가지 기능을 추가로 지원합니다

func MakeBacklog(execPool ExecutionPool, backlogSize int, priority Priority, owner interface{}) BacklogPool

type ExecFunc ¶

type ExecFunc func(interface{}) interface{}

A ExecFunc is a unit of work to be executed by a Pool goroutine.

Note that a ExecFunc will occupy a Pool goroutine, so do not schedule tasks that spend an excessive amount of time waiting.

type ExecutionPool ¶

type ExecutionPool interface {
	Enqueue(enqueueCtx context.Context, t ExecFunc, arg interface{}, i Priority, out chan interface{}) error
	GetOwner() interface{}
	Shutdown()
	GetParallelism() int
}

ExecutionPool interface exposes the core functionality of the execution pool.

func MakePool(owner interface{}) ExecutionPool

type Priority ¶

type Priority uint8

A Priority specifies a hint to the Pool to execute a Task at some priority.

Tasks with higher Priority values will tend to finish more quickly.

If there are tasks with different priorities, a worker will pick the highest-priority task to execute next.

const (
	LowPriority Priority = iota
	HighPriority
)
