Functions

func FromPipeline

func FromPipeline(pipe *pipeline.Pipeline, log logger.Logger, cfg config.Configurer, e events.Handler, pq priorityqueue.Queue) (*consumer, error)

func NewBeanstalkConsumer

func NewBeanstalkConsumer(configKey string, log logger.Logger, cfg config.Configurer, e events.Handler, pq priorityqueue.Queue) (*consumer, error)

Types

type Config

type Config struct {
	PipePriority   int64         `mapstructure:"priority"`
	TubePriority   *uint32       `mapstructure:"tube_priority"`
	Tube           string        `mapstructure:"tube"`
	ReserveTimeout time.Duration `mapstructure:"reserve_timeout"`
}

func (*Config) InitDefault

func (c *Config) InitDefault()

type ConnPool

type ConnPool struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

func NewConnPool

func NewConnPool(network, address, tName string, tout time.Duration, log logger.Logger) (*ConnPool, error)

func (*ConnPool) Delete

func (cp *ConnPool) Delete(_ context.Context, id uint64) error

func (*ConnPool) Put

func (cp *ConnPool) Put(_ context.Context, body []byte, pri uint32, delay, ttr time.Duration) (uint64, error)

Put the payload TODO use the context ??

func (*ConnPool) Reserve

func (cp *ConnPool) Reserve(reserveTimeout time.Duration) (uint64, []byte, error)

Reserve reserves and returns a job from one of the tubes in t. If no job is available before time timeout has passed, Reserve returns a ConnError recording ErrTimeout.

Typically, a client will reserve a job, perform some work, then delete the job with Conn.Delete.

func (*ConnPool) Stats

func (cp *ConnPool) Stats(_ context.Context) (map[string]string, error)

type GlobalCfg

type GlobalCfg struct {
	Addr    string        `mapstructure:"addr"`
	Timeout time.Duration `mapstructure:"timeout"`
}

func (*GlobalCfg) InitDefault

func (c *GlobalCfg) InitDefault()

type Item

type Item struct {
	// Job contains pluginName of job broker (usually PHP class).
	Job string `json:"job"`

	// Ident is unique identifier of the job, should be provided from outside
	Ident string `json:"id"`

	// Payload is string data (usually JSON) passed to Job broker.
	Payload string `json:"payload"`

	// Headers with key-values pairs
	Headers map[string][]string `json:"headers"`

	// Options contains set of PipelineOptions specific to job execution. Can be empty.
	Options *Options `json:"options,omitempty"`
}

func (*Item) Ack

func (i *Item) Ack() error

func (*Item) Body

func (i *Item) Body() []byte

Body packs job payload into binary payload.

func (*Item) Context

func (i *Item) Context() ([]byte, error)

Context packs job context (job, id) into binary payload. Not used in the sqs, MessageAttributes used instead

func (*Item) ID

func (i *Item) ID() string

func (*Item) Nack

func (i *Item) Nack() error

func (*Item) Priority

func (i *Item) Priority() int64

func (*Item) Requeue

func (i *Item) Requeue(headers map[string][]string, delay int64) error

type Options

type Options struct {
	// Priority is job priority, default - 10
	// pointer to distinguish 0 as a priority and nil as priority not set
	Priority int64 `json:"priority"`

	// Pipeline manually specified pipeline.
	Pipeline string `json:"pipeline,omitempty"`

	// Delay defines time duration to delay execution for. Defaults to none.
	Delay int64 `json:"delay,omitempty"`
	// contains filtered or unexported fields
}

Options carry information about how to handle given job.

func (*Options) DelayDuration

func (o *Options) DelayDuration() time.Duration

DelayDuration returns delay duration in a form of time.Duration.

type Plugin

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

func (*Plugin) Available

func (p *Plugin) Available()

func (*Plugin) FromPipeline

func (p *Plugin) FromPipeline(pipe *pipeline.Pipeline, eh events.Handler, pq priorityqueue.Queue) (jobs.Consumer, error)

func (*Plugin) Init

func (p *Plugin) Init(log logger.Logger, cfg config.Configurer) error

func (*Plugin) JobsConstruct

func (p *Plugin) JobsConstruct(configKey string, eh events.Handler, pq priorityqueue.Queue) (jobs.Consumer, error)

func (*Plugin) Name

func (p *Plugin) Name() string

func (*Plugin) Serve

func (p *Plugin) Serve() chan error

func (*Plugin) Stop

func (p *Plugin) Stop() error
