[Question] How to set special redis db

[caubechankiu]

Here is FlowService struct

type FlowService struct {
	Port                    int
	RedisURL                string
	RedisPassword           string
	RequestAuthSharedSecret string
	RequestAuthEnabled      bool
	WorkerConcurrency       int
	RetryCount              int
	Flows                   map[string]runtime.FlowDefinitionHandler
	RequestReadTimeout      time.Duration
	RequestWriteTimeout     time.Duration
	OpenTraceUrl            string
	DataStore               sdk.DataStore
	Logger                  sdk.Logger
	EnableMonitoring        bool
	DebugEnabled            bool

	runtime *runtime.FlowRuntime
}

I want to connect to a specifically redis db, but FlowService don't have a field like RedisDB
