Types

type Config

type Config struct {
	// how much buffer time there is between a transaction being ingested by a
	// collection node and being included in a collection and block
	ExpiryBuffer uint
	// the maximum transaction gas limit
	MaxGasLimit uint64
	// whether or not we check that transaction scripts are parse-able
	CheckScriptsParse bool
	// the maximum address index we accept
	MaxAddressIndex uint64
	// how many extra nodes in the responsible cluster we propagate transactions to
	// (we always send to at least one)
	PropagationRedundancy uint
	// the maximum transaction byte size limit
	MaxTransactionByteSize uint64
	// maximum collection byte size, it acts as hard limit max for the tx size.
	MaxCollectionByteSize uint64
}

Config defines configuration for the transaction ingest engine.

func DefaultConfig

func DefaultConfig() Config

type Engine

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

Engine is the transaction ingestion engine, which ensures that new transactions are delegated to the correct collection cluster, and prepared to be included in a collection.

func New

func New(
	log zerolog.Logger,
	net network.Network,
	state protocol.State,
	engMetrics module.EngineMetrics,
	colMetrics module.CollectionMetrics,
	me module.Local,
	chain flow.Chain,
	pools *epochs.TransactionPools,
	config Config,
) (*Engine, error)

New creates a new collection ingest engine.

func (*Engine) Done

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

Done returns a done channel that is closed once the engine has fully stopped.

func (*Engine) Process

func (e *Engine) Process(channel network.Channel, 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.

func (*Engine) Submit

func (e *Engine) Submit(channel network.Channel, 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.
