Golang NewFileProvider Examples

Example #1

File: main.go Project: jmptrader/talaria

func run(c *cli.Context) {
	validateFlags(c)
	setLogLevel(c)

	clientAddr := fmt.Sprintf("http://localhost:%d", c.Int(port))
	kvStore := kvstore.New(clientAddr, c.Int(healthPort))
	ioProvider := broker.NewFileProvider(c.String(dataDir), uint64(c.Int(segmentLength)), uint64(c.Int(numSegments)), time.Second)
	orch := orchestrator.New(clientAddr, uint(c.Int(numReplicas)), ioProvider, kvStore)

	broker.StartBrokerServer(c.Int(port), orch, ioProvider)
}
