Functions

func OpenCache

func OpenCache(ctx context.Context, log *zap.Logger, config Config) (accounting.Cache, error)

OpenCache creates a new accounting.Cache instance using the type specified backend in the provided config.

The cache instance may be returned despite of returning the accounting.ErrSystemOrNetError because some backends allows to reconnect on each operation if the connection was not established or it was disconnected, which is what it could happen at the moment to instance it and the cache will work one the backend system will be reachable later on. For this reason, the components that uses the cache should operate despite the backend is not responding successfully although their service is degraded.

Types

type Config

type Config struct {
	StorageBackend     string        `help:"what to use for storing real-time accounting data"`
	BandwidthCacheTTL  time.Duration `default:"5m" help:"bandwidth cache key time to live"`
	AsOfSystemInterval time.Duration `default:"-10s" devDefault:"-1us" testDefault:"-1us" help:"as of system interval"`
	BatchSize          int           `default:"5000" help:"how much projects usage should be requested from redis cache at once"`
}

Config contains configurable values for the live accounting service.
