func SubscribeAndStoreChannelEvents(ctx context.Context, client lndClientSubscribeChannelEvent, db *sqlx.DB,
	nodeSettings commons.ManagedNodeSettings, eventChannel chan interface{}) error

SubscribeAndStoreChannelEvents Subscribes to channel events from LND and stores them in the database as a time series

func SubscribeAndStoreChannelGraph 

func SubscribeAndStoreChannelGraph(ctx context.Context, client subscribeChannelGrpahClient, db *sqlx.DB,
