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 Option

type Option func(c *Options)

Option is a function that sets some option on the writer.

func IndexFilter

func IndexFilter(indexFilter dbmodel.IndexFilter) Option

IndexFilter can be provided to filter certain spans that should not be indexed.

func StoreIndexesOnly

func StoreIndexesOnly() Option

StoreIndexesOnly can be provided to skip storing spans, and only store span indexes.

func StoreWithoutIndexing

func StoreWithoutIndexing() Option

StoreWithoutIndexing can be provided to store spans without indexing them.

func TagFilter

func TagFilter(tagFilter dbmodel.TagFilter) Option

TagFilter can be provided to filter any tags that should not be indexed.

type Options

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

Options control behavior of the writer.

type ServiceNamesStorage

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

ServiceNamesStorage stores known service names.

func NewServiceNamesStorage

func NewServiceNamesStorage(
	session cassandra.Session,

func (*ServiceNamesStorage) GetServices

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 (*SpanReader) FindTraces

func (s *SpanReader) FindTraces(ctx context.Context, traceQuery *spanstore.TraceQueryParameters) ([]*model.Trace, error)

FindTraces retrieves traces that match the traceQuery

func (s *SpanReader) GetTrace(ctx context.Context, 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

func NewSpanWriter

func NewSpanWriter(
	session cassandra.Session,
