Functions

func GetQueryTerminatorTagName

func GetQueryTerminatorTagName(query string) []byte

GetQueryTerminatorTagName will return the name for the terminator matcher in the given pattern. This is useful for filtering out any additional results.

func TranslateQueryToMatchersWithTerminator added in v0.8.0

func TranslateQueryToMatchersWithTerminator(
	query string,
) (models.Matchers, error)

TranslateQueryToMatchersWithTerminator converts a graphite query to tag matcher pairs, and adds a terminator matcher to the end.

Types

type DataOptions

type DataOptions struct {
	// Timeout determines a custom timeout for the context. If set to 0, uses
	// the default timeout.
	Timeout time.Duration
	// Limit is the limit for number of datapoints to retrieve.
	Limit int
}

DataOptions provide data context.

type FetchOptions

type FetchOptions struct {
	// StartTime is the start time for the fetch.
	StartTime time.Time
	// EndTime is the end time for the fetch.
	EndTime time.Time
	// DataOptions are the options for the fetch.
	DataOptions
	// Source is the query source.
	Source []byte
}

FetchOptions provides context to a fetch expression.

type FetchResult

type FetchResult struct {
	// SeriesList is the aggregated list of results across all underlying storage
	// calls.
	SeriesList []*ts.Series
	// Metadata contains any additional metadata indicating information about
	// series execution.
	Metadata block.ResultMetadata
}

FetchResult provides a fetch result and meta information.

func NewFetchResult

func NewFetchResult(
	ctx context.Context,
	seriesList []*ts.Series,
	resultMeta block.ResultMetadata,
) *FetchResult

NewFetchResult is a convenience method for creating a FetchResult.

func (*FetchResult) Close

func (fr *FetchResult) Close() error

Close will return the fetch result to the pool.

func (*FetchResult) Reset

func (fr *FetchResult) Reset()

Reset will wipe out existing fetch result data.

type M3WrappedStorageOptions struct {
	AggregateNamespacesAllData                 bool
	ShiftTimeStart                             time.Duration
	ShiftTimeEnd                               time.Duration
	ShiftStepsStart                            int
	ShiftStepsEnd                              int
	ShiftStepsStartWhenAtResolutionBoundary    *int
	ShiftStepsEndWhenAtResolutionBoundary      *int
	ShiftStepsStartWhenEndAtResolutionBoundary *int
	ShiftStepsEndWhenStartAtResolutionBoundary *int
	RenderPartialStart                         bool
	RenderPartialEnd                           bool
	RenderSeriesAllNaNs                        bool
	CompileEscapeAllNotOnlyQuotes              bool
}

M3WrappedStorageOptions is the graphite storage options.

type MockStorage added in v0.15.12

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

MockStorage is a mock of Storage interface

func NewMockStorage added in v0.15.12

func NewMockStorage(ctrl *gomock.Controller) *MockStorage

NewMockStorage creates a new mock instance

func (*MockStorage) EXPECT added in v0.15.12

func (m *MockStorage) EXPECT() *MockStorageMockRecorder

EXPECT returns an object that allows the caller to indicate expected use

func (*MockStorage) FetchByQuery added in v0.15.12

func (m *MockStorage) FetchByQuery(arg0 context.Context, arg1 string, arg2 FetchOptions) (*FetchResult, error)

FetchByQuery mocks base method

type MockStorageMockRecorder added in v0.15.12

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

MockStorageMockRecorder is the mock recorder for MockStorage

func (*MockStorageMockRecorder) FetchByQuery added in v0.15.12

func (mr *MockStorageMockRecorder) FetchByQuery(arg0, arg1, arg2 interface{}) *gomock.Call

FetchByQuery indicates an expected call of FetchByQuery

type Storage

type Storage interface {
	// FetchByQuery fetches timeseries data based on a query.
	FetchByQuery(
		ctx context.Context, query string, opts FetchOptions,
	) (*FetchResult, error)
}

Storage provides an interface for retrieving timeseries values or names based upon a query or path.

func NewM3WrappedStorage

func NewM3WrappedStorage(
	m3storage storage.Storage,
	m3dbOpts m3db.Options,
	instrumentOpts instrument.Options,
	opts M3WrappedStorageOptions,
) Storage

NewM3WrappedStorage creates a graphite storage wrapper around an m3query storage instance.
