Types

type OperationNamesStorage

type OperationNamesStorage struct {
	// CQL statements are public so that Cassandra2 storage can override them
	InsertStmt string
	QueryStmt  string
	// contains filtered or unexported fields
}

OperationNamesStorage stores known operation names by service.

func NewOperationNamesStorage

func NewOperationNamesStorage(
	session cassandra.Session,
	writeCacheTTL time.Duration,
	metricsFactory metrics.Factory,
	logger *zap.Logger,
) *OperationNamesStorage

NewOperationNamesStorage returns a new OperationNamesStorage

func (*OperationNamesStorage) GetOperations

func (s *OperationNamesStorage) GetOperations(service string) ([]string, error)

GetOperations returns all operations for a specific service traced by Jaeger

func (*OperationNamesStorage) Write

func (s *OperationNamesStorage) Write(serviceName string, operationName string) error

Write saves Operation and Service name tuples

type ServiceNamesStorage

type ServiceNamesStorage struct {
	InsertStmt string
	QueryStmt  string
	// contains filtered or unexported fields
}

ServiceNamesStorage stores known service names.

func NewServiceNamesStorage

func (s *ServiceNamesStorage) GetServices() ([]string, error)

GetServices returns all services traced by Jaeger

func (*ServiceNamesStorage) Write

func (s *ServiceNamesStorage) Write(serviceName string) error

Write saves a single service name

type SpanReader

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

SpanReader can query for and load traces from Cassandra.

func NewSpanReader

func NewSpanReader(
	session cassandra.Session,
	metricsFactory metrics.Factory,
	logger *zap.Logger,
) *SpanReader

NewSpanReader returns a new SpanReader.

func (s *SpanReader) GetServices() ([]string, error)

GetServices returns all services traced by Jaeger

func (*SpanReader) GetTrace

func (s *SpanReader) GetTrace(traceID model.TraceID) (*model.Trace, error)

GetTrace takes a traceID and returns a Trace associated with that traceID

type SpanWriter

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

SpanWriter handles all writes to Cassandra for the Jaeger data model
