Functions ¶
func NewHTTPServer ¶
NewHTTPServer creates and intializes a new HTTP GRPC proxy server
func NewRateLimiterInterceptor ¶ added in v0.14.8
func NewRateLimiterInterceptor(log zerolog.Logger, apiRateLimits map[string]int, apiBurstLimits map[string]int) *rateLimiterInterceptor
NewRateLimiterInterceptor creates a new rate limiter interceptor with the defined per second rate limits and the optional burst limit for each API.
Types ¶
type Config ¶
type Config struct {
	GRPCListenAddr            string        // the GRPC server address as ip:port
	HTTPListenAddr            string        // the HTTP web proxy address as ip:port
	CollectionAddr            string        // the address of the upstream collection node
	HistoricalAccessAddrs     string        // the list of all access nodes from previous spork
	MaxMsgSize                int           // GRPC max message size
	ExecutionClientTimeout    time.Duration // execution API GRPC client timeout
	CollectionClientTimeout   time.Duration // collection API GRPC client timeout
	MaxHeightRange            uint          // max size of height range requests
	PreferredExecutionNodeIDs []string      // preferred list of upstream execution node IDs
	FixedExecutionNodeIDs     []string      // fixed list of execution node IDs to choose from if no node node ID can be chosen from the PreferredExecutionNodeIDs
}
    Config defines the configurable options for the access node server
type Engine ¶
type Engine struct {
	// contains filtered or unexported fields
}
    Engine implements a gRPC server with a simplified version of the Observation API.
func New ¶
func New(log zerolog.Logger, state protocol.State, config Config, collectionRPC accessproto.AccessAPIClient, historicalAccessNodes []accessproto.AccessAPIClient, blocks storage.Blocks, headers storage.Headers, collections storage.Collections, transactions storage.Transactions, executionReceipts storage.ExecutionReceipts, chainID flow.ChainID, transactionMetrics module.TransactionMetrics, collectionGRPCPort uint, executionGRPCPort uint, retryEnabled bool, rpcMetricsEnabled bool, apiRatelimits map[string]int, apiBurstLimits map[string]int, ) *Engine
New returns a new RPC engine.
func (*Engine) Done ¶
func (e *Engine) Done() <-chan struct{}
Done returns a done channel that is closed once the engine has fully stopped. It sends a signal to stop the gRPC server, then closes the channel.
func (*Engine) GRPCAddress ¶ added in v0.14.8
func (*Engine) Ready ¶
func (e *Engine) Ready() <-chan struct{}
Ready returns a ready channel that is closed once the engine has fully started. The RPC engine is ready when the gRPC server has successfully started.
func (*Engine) SubmitLocal ¶
func (e *Engine) SubmitLocal(event interface{})
SubmitLocal submits an event originating on the local node.
