Types

type Engine

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

Engine represents the ingestion engine, used to funnel collections from a cluster of collection nodes to the set of consensus nodes. It represents the link between collection nodes and consensus nodes and has a counterpart with the same engine ID in the collection node.

func New

func New(
	log zerolog.Logger,
	tracer module.Tracer,
	metrics module.EngineMetrics,
	spans module.ConsensusMetrics,
	mempool module.MempoolMetrics,
	net module.Network,
	state protocol.State,
	headers storage.Headers,
	me module.Local,
	pool mempool.Guarantees,
) (*Engine, error)

New creates a new collection propagation engine.

func (*Engine) Done

func (e *Engine) Done() <-chan struct{}

Done returns a done channel that is closed once the engine has fully stopped. For the ingestion engine, it only waits for all submit goroutines to end.

func (*Engine) Process

func (e *Engine) Process(originID flow.Identifier, event interface{}) error

Process processes the given event from the node with the given origin ID in a blocking manner. It returns the potential processing error when done.

func (*Engine) ProcessLocal

func (e *Engine) ProcessLocal(event interface{}) error

ProcessLocal processes an event originating on the local node.

func (*Engine) Ready

func (e *Engine) Ready() <-chan struct{}

Ready returns a ready channel that is closed once the engine has fully started. For the ingestion engine, we consider the engine up and running upon initialization.

func (*Engine) Submit

func (e *Engine) Submit(originID flow.Identifier, event interface{})

Submit submits the given event from the node with the given origin ID for processing in a non-blocking manner. It returns instantly and logs a potential processing error internally when done.

func (*Engine) SubmitLocal

func (e *Engine) SubmitLocal(event interface{})

SubmitLocal submits an event originating on the local node.
