Types

type Config

type Config struct {
	// NumPollers configures number of priority queue pollers
	// Default - num logical cores
	NumPollers int `mapstructure:"num_pollers"`

	// PipelineSize is the limit of a main jobs queue which consume Items from the drivers pipeline
	// Driver pipeline might be much larger than a main jobs queue
	PipelineSize uint64 `mapstructure:"pipeline_size"`

	// Timeout in seconds is the per-push limit to put the job into queue
	Timeout int `mapstructure:"timeout"`

	// Pool configures roadrunner workers pool.
	Pool *poolImpl.Config `mapstructure:"pool"`

	// Pipelines defines mapping between PHP job pipeline and associated job broker.
	Pipelines map[string]Pipeline `mapstructure:"pipelines"`

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"`
	// AutoAck use to ack a job right after it arrived from the driver
	AutoAck bool `json:"auto_ack"`

	// kafka specific fields
	// Topic is kafka topic
	Topic string `json:"topic"`
	// Optional metadata
	Metadata string `json:"metadata"`
