Functions

func AddFlags

func AddFlags(flagSet *flag.FlagSet)

AddFlags from this storage to the CLI

Types

type Factory

type Factory struct {
	// contains filtered or unexported fields
}

Factory implements storage.Factory and creates storage components backed by memory store.

func NewFactory

func NewFactory() *Factory

NewFactory creates a new Factory.

func (*Factory) AddFlags

func (f *Factory) AddFlags(flagSet *flag.FlagSet)

AddFlags implements plugin.Configurable

func (*Factory) CreateDependencyReader

func (f *Factory) CreateDependencyReader() (dependencystore.Reader, error)

CreateDependencyReader implements storage.Factory

func (*Factory) CreateSpanReader

func (f *Factory) CreateSpanReader() (spanstore.Reader, error)

CreateSpanReader implements storage.Factory

func (*Factory) CreateSpanWriter

func (f *Factory) CreateSpanWriter() (spanstore.Writer, error)

CreateSpanWriter implements storage.Factory

func (*Factory) InitFromOptions

func (f *Factory) InitFromOptions(opts Options)

InitFromOptions initializes factory from the supplied options

func (*Factory) InitFromViper

func (f *Factory) InitFromViper(v *viper.Viper)

InitFromViper implements plugin.Configurable

func (*Factory) Initialize

func (f *Factory) Initialize(metricsFactory metrics.Factory, logger *zap.Logger) error

Initialize implements storage.Factory

type Options

type Options struct {
	Configuration config.Configuration `mapstructure:",squash"`
}

Options stores the configuration entries for this storage

func (*Options) InitFromViper

func (opt *Options) InitFromViper(v *viper.Viper)

InitFromViper initializes the options struct with values from Viper

type Store

type Store struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Store is an in-memory store of traces

func NewStore

func NewStore() *Store

NewStore creates an unbounded in-memory store

func WithConfiguration

func WithConfiguration(configuration config.Configuration) *Store

WithConfiguration creates a new in memory storage based on the given configuration

func (*Store) FindTraceIDs

FindTraceIDs is not implemented.

func (*Store) FindTraces

func (m *Store) FindTraces(ctx context.Context, query *spanstore.TraceQueryParameters) ([]*model.Trace, error)

FindTraces returns all traces in the query parameters are satisfied by a trace's span

func (*Store) GetDependencies

func (m *Store) GetDependencies(ctx context.Context, endTs time.Time, lookback time.Duration) ([]model.DependencyLink, error)

GetDependencies returns dependencies between services

func (*Store) GetOperations

func (m *Store) GetOperations(
	ctx context.Context,
	query spanstore.OperationQueryParameters,
) ([]spanstore.Operation, error)

GetOperations returns the operations of a given service

func (*Store) GetServices

func (m *Store) GetServices(ctx context.Context) ([]string, error)
