Types

type Config

type Config struct {
	Priority int64 `mapstructure:"priority"`
	Prefetch int64 `mapstructure:"prefetch"`
}

type Configurer

type Configurer interface {
	// UnmarshalKey takes a single key and unmarshal it into a Struct.
	UnmarshalKey(name string, out any) error
	// Has checks if a config section exists.
	Has(name string) bool
}

type Driver

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

func FromConfig

func FromConfig(
	tracer *sdktrace.TracerProvider,
	configKey string,
	log *zap.Logger,
	cfg Configurer,
	pipeline jobs.Pipeline,
	pq jobs.Queue) (*Driver, error)

FromConfig initializes kafka pipeline from the configuration

func FromPipeline

func FromPipeline(
	tracer *sdktrace.TracerProvider,
	pipeline jobs.Pipeline,
	log *zap.Logger,
	pq jobs.Queue,
) (*Driver, error)

FromPipeline initializes pipeline on-the-fly

func (*Driver) State

func (c *Driver) State(ctx context.Context) (*jobs.State, error)

func (*Driver) Stop

func (c *Driver) Stop(ctx context.Context) error

type Item

type Item struct {
	// Job contains the name of job broker (usually PHP class).
	Job string `json:"job"`
	// Ident is a 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 []byte `json:"payload"`

	// Options contain a set of PipelineOptions specific to job execution. Can be empty.
	Options *Options `json:"options,omitempty"`
	// contains filtered or unexported fields
}

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

type Options

type Options struct {
	// Priority is job priority, default - 10
	// pointer to distinguish 0 as a priority and nil as a 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.

	// contains filtered or unexported fields
}

Options carry information about how to handle a given job.

func (*Options) DelayDuration
