Types ¶
type BulkExecutor ¶
type BulkExecutor struct {
// contains filtered or unexported fields
}
A BulkExecutor is an executor that can execute tasks on either requirement meets: 1. up to given size of tasks 2. flush interval time elapsed
func NewBulkExecutor ¶
func NewBulkExecutor(execute Execute, opts ...BulkOption) *BulkExecutor
NewBulkExecutor returns a BulkExecutor.
func (*BulkExecutor) Flush ¶
func (be *BulkExecutor) Flush()
Flush forces be to flush and execute tasks.
func (*BulkExecutor) Wait ¶
func (be *BulkExecutor) Wait()
Wait waits be to done with the task execution.
type BulkOption ¶
type BulkOption func(options *bulkOptions)
BulkOption defines the method to customize a BulkExecutor.
func WithBulkInterval ¶
func WithBulkInterval(duration time.Duration) BulkOption
WithBulkInterval customizes a BulkExecutor with given flush interval.
func WithBulkTasks ¶
func WithBulkTasks(tasks int) BulkOption
WithBulkTasks customizes a BulkExecutor with given tasks limit.
type ChunkExecutor ¶
type ChunkExecutor struct {
// contains filtered or unexported fields
}
A ChunkExecutor is an executor to execute tasks when either requirement meets: 1. up to given chunk size 2. flush interval elapsed
func NewChunkExecutor ¶
func NewChunkExecutor(execute Execute, opts ...ChunkOption) *ChunkExecutor
NewChunkExecutor returns a ChunkExecutor.
func (*ChunkExecutor) Add ¶
func (ce *ChunkExecutor) Add(task any, size int) error
Add adds task with given chunk size into ce.
func (*ChunkExecutor) Flush ¶
func (ce *ChunkExecutor) Flush()
Flush forces ce to flush and execute tasks.
type ChunkOption ¶
type ChunkOption func(options *chunkOptions)
ChunkOption defines the method to customize a ChunkExecutor.
func WithChunkBytes ¶
func WithChunkBytes(size int) ChunkOption
WithChunkBytes customizes a ChunkExecutor with the given chunk size.
func WithFlushInterval ¶
func WithFlushInterval(duration time.Duration) ChunkOption
WithFlushInterval customizes a ChunkExecutor with the given flush interval.
type DelayExecutor ¶
type DelayExecutor struct {
// contains filtered or unexported fields
}
A DelayExecutor delays a tasks on given delay interval.
func NewDelayExecutor ¶
func NewDelayExecutor(fn func(), delay time.Duration) *DelayExecutor
NewDelayExecutor returns a DelayExecutor with given fn and delay.
func (*DelayExecutor) Trigger ¶
func (de *DelayExecutor) Trigger()
Trigger triggers the task to be executed after given delay, safe to trigger more than once.
type LessExecutor ¶
type LessExecutor struct {
// contains filtered or unexported fields
}
A LessExecutor is an executor to limit execution once within given time interval.
func NewLessExecutor ¶
func NewLessExecutor(threshold time.Duration) *LessExecutor
NewLessExecutor returns a LessExecutor with given threshold as time interval.
func (*LessExecutor) DoOrDiscard ¶
func (le *LessExecutor) DoOrDiscard(execute func()) bool
DoOrDiscard executes or discards the task depends on if another task was executed within the time interval.
type PeriodicalExecutor ¶
type PeriodicalExecutor struct {
// contains filtered or unexported fields
}
A PeriodicalExecutor is an executor that periodically execute tasks.
func NewPeriodicalExecutor ¶
func NewPeriodicalExecutor(interval time.Duration, container TaskContainer) *PeriodicalExecutor
NewPeriodicalExecutor returns a PeriodicalExecutor with given interval and container.
func (*PeriodicalExecutor) Add ¶
func (pe *PeriodicalExecutor) Add(task any)
Add adds tasks into pe.
func (*PeriodicalExecutor) Flush ¶
func (pe *PeriodicalExecutor) Flush() bool
Flush forces pe to execute tasks.
func (*PeriodicalExecutor) Sync ¶
func (pe *PeriodicalExecutor) Sync(fn func())
Sync lets caller to run fn thread-safe with pe, especially for the underlying container.
func (*PeriodicalExecutor) Wait ¶
func (pe *PeriodicalExecutor) Wait()
Wait waits the execution to be done.
type TaskContainer ¶
type TaskContainer interface {
// AddTask adds the task into the container.
// Returns true if the container needs to be flushed after the addition.
AddTask(task any) bool
// Execute handles the collected tasks by the container when flushing.
Execute(tasks any)
// RemoveAll removes the contained tasks, and return them.
RemoveAll() any
}
TaskContainer interface defines a type that can be used as the underlying container that used to do periodical executions.
