Functions ¶
func New ¶
func New( log zerolog.Logger, edrMetrics module.ExecutionDataRequesterMetrics, eds state_synchronization.ExecutionDataService, processedHeight storage.ConsumerProgress, processedNotifications storage.ConsumerProgress, state protocol.State, headers storage.Headers, results storage.ExecutionResults, seals storage.Seals, cfg ExecutionDataConfig, ) state_synchronization.ExecutionDataRequester
New creates a new execution data requester component
Types ¶
type ExecutionDataConfig ¶
type ExecutionDataConfig struct {
// The initial value to use as the last processed block height. This should be the
// first block height to sync - 1
InitialBlockHeight uint64
// Max number of unsent notifications to allow before pausing new fetches. After exceeding this
// limit, the requester will stop processing new finalized block notifications. This prevents
// unbounded memory use by the requester if it gets stuck fetching a specific height.
MaxSearchAhead uint64
// The initial timeout for fetching ExecutionData from the db/network
FetchTimeout time.Duration
// The max timeout for fetching ExecutionData from the db/network
MaxFetchTimeout time.Duration
// Exponential backoff settings for download retries
RetryDelay time.Duration
MaxRetryDelay time.Duration
}
ExecutionDataConfig contains configuration options for the ExecutionDataRequester
