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 {
UnsecureGRPCListenAddr string // the non-secure GRPC server address as ip:port
SecureGRPCListenAddr string // the secure GRPC server address as ip:port
TransportCredentials credentials.TransportCredentials // the secure GRPC credentials
HTTPListenAddr string // the HTTP web proxy address as ip:port
RESTListenAddr string // the REST server address as ip:port (if empty the REST server will not be started)
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 A secure GRPC server here implies a server that presents a self-signed TLS certificate and a client that authenticates the server via a pre-shared public key
type Engine ¶
type Engine struct {
// contains filtered or unexported fields
}
Engine exposes the server with a simplified version of the Access API. An unsecured GRPC server (default port 9000), a secure GRPC server (default port 9001) and an HTTP Web proxy (default port 8000) are brought up.
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, executionResults storage.ExecutionResults, 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) 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) RestApiAddress ¶ added in v0.23.2
func (*Engine) SecureGRPCAddress ¶ added in v0.20.0
func (*Engine) SubmitLocal ¶
func (e *Engine) SubmitLocal(event interface{})
SubmitLocal submits an event originating on the local node.
