Functions

func Flatten

func Flatten(i interface{}) []string

Flatten performs a depth-first serialization of a struct to a slice of strings. Each string will be formatted at 'path.to.leaf = value'.

type Authentication

type Authentication struct {
	TimeWindow time.Duration
}

Authentication contains configuration parameters related to authenticating client messages.

type Cluster

type Cluster struct {

}

Consumer contains configuration for the consumer's retries when failing to read from a Kafa partition.

type Debug

type Debug struct {
	BroadcastTraceDir string
	DeliverTraceDir   string
}

Debug contains configuration for the orderer's debug parameters.

type FileLedger

type FileLedger struct {
	Location string
	Prefix   string
}

FileLedger contains configuration for the file-based ledger.

type General

type General struct {
	LedgerType     string
	ListenAddress  string
	ListenPort     uint16
	TLS            TLS
	Cluster        Cluster
	Keepalive      Keepalive
	GenesisMethod  string
	GenesisProfile string
	SystemChannel  string
	GenesisFile    string
	Profile        Profile
	LocalMSPDir    string
	LocalMSPID     string
	BCCSP          *bccsp.FactoryOpts
	Authentication Authentication
}

General contains config which should be common among all orderer types.

type Kafka

type Kafka struct {
	Retry     Retry
	Verbose   bool
	Version   sarama.KafkaVersion // TODO Move this to global config
	TLS       TLS
	SASLPlain SASLPlain
	Topic     Topic
}

Kafka contains configuration for the Kafka-based orderer.

type Keepalive

type Keepalive struct {
	ServerMinInterval time.Duration
	ServerInterval    time.Duration
	ServerTimeout     time.Duration
}

Keepalive contains configuration for gRPC servers.

type Metadata

type Metadata struct {
	RetryMax     int
	RetryBackoff time.Duration
}

Metadata contains configuration for the metadata requests to the Kafka cluster.

type Metrics

type Metrics struct {
	Provider string
	Statsd   Statsd
}

Operations confiures the metrics provider for the orderer.

type NetworkTimeouts

type NetworkTimeouts struct {
	DialTimeout  time.Duration
	ReadTimeout  time.Duration
	WriteTimeout time.Duration
}

NetworkTimeouts contains the socket timeouts for network requests to the Kafka cluster.

type Operations

type Operations struct {
	ListenAddress string
	TLS           TLS
}

Operations configures the operations endpont for the orderer.

type Producer

type Producer struct {
	RetryMax     int
	RetryBackoff time.Duration
}

Producer contains configuration for the producer's retries when failing to post a message to a Kafka partition.

type Profile

type Profile struct {
	Enabled bool
	Address string
}

Profile contains configuration for Go pprof profiling.

type RAMLedger

type RAMLedger struct {
	HistorySize uint
}

RAMLedger contains configuration for the RAM ledger.

type Retry

type Retry struct {
	ShortInterval   time.Duration
	ShortTotal      time.Duration
