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) 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) Initialize

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

Initialize implements storage.Factory

type Store

type Store struct {
	// TODO: make this a bounded memory store
	sync.RWMutex
	// contains filtered or unexported fields
}

Store is an unbounded in-memory store of traces

func NewStore

func NewStore() *Store

NewStore creates an in-memory store

func (*Store) FindTraces

func (m *Store) FindTraces(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(endTs time.Time, lookback time.Duration) ([]model.DependencyLink, error)

GetDependencies returns dependencies between services

func (*Store) GetOperations

func (m *Store) GetOperations(service string) ([]string, error)

GetOperations returns the operations of a given service

func (*Store) GetServices

func (m *Store) GetServices() ([]string, error)

GetServices returns a list of all known services

func (*Store) GetTrace

func (m *Store) GetTrace(traceID model.TraceID) (*model.Trace, error)

GetTrace gets a trace

func (*Store) WriteSpan

func (m *Store) WriteSpan(span *model.Span) error

WriteSpan writes the given span
