Functions

func HashPrefix

func HashPrefix(input string) string

HashPrefix calculates a 64bit hash of the input string and hex-encodes the result, taking care to zero pad etc.

func NewBigtableObjectClient

func NewBigtableObjectClient(ctx context.Context, cfg Config, schemaCfg chunk.SchemaConfig) (chunk.Client, error)

NewBigtableObjectClient makes a new chunk.Client that stores chunks in Bigtable.

func NewStorageClientColumnKey

func NewStorageClientColumnKey(ctx context.Context, cfg Config, schemaCfg chunk.SchemaConfig) (chunk.IndexClient, error)

NewStorageClientColumnKey returns a new v2 StorageClient.

func NewStorageClientV1

func NewStorageClientV1(ctx context.Context, cfg Config, schemaCfg chunk.SchemaConfig) (chunk.IndexClient, error)

NewStorageClientV1 returns a new v1 StorageClient.

func NewTableClient

func NewTableClient(ctx context.Context, cfg Config) (chunk.TableClient, error)

NewTableClient returns a new TableClient.

}

GCSConfig is config for the GCS Chunk Client.

func (*GCSConfig) RegisterFlags

func (cfg *GCSConfig) RegisterFlags(f *flag.FlagSet)

RegisterFlags registers flags.

func (*GCSConfig) RegisterFlagsWithPrefix

func (cfg *GCSConfig) RegisterFlagsWithPrefix(prefix string, f *flag.FlagSet)

RegisterFlagsWithPrefix registers flags with prefix.

type GCSObjectClient

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

func NewGCSObjectClient

func NewGCSObjectClient(ctx context.Context, cfg GCSConfig, hedgingCfg hedging.Config) (*GCSObjectClient, error)

NewGCSObjectClient makes a new chunk.Client that writes chunks to GCS.

DeleteObject deletes the specified object key from the configured GCS bucket.

func (*GCSObjectClient) GetObject

func (s *GCSObjectClient) GetObject(ctx context.Context, objectKey string) (io.ReadCloser, int64, error)

GetObject returns a reader and the size for the specified object key from the configured GCS bucket.

func (*GCSObjectClient) IsObjectNotFoundErr

func (s *GCSObjectClient) IsObjectNotFoundErr(err error) bool

IsObjectNotFoundErr returns true if error means that object is not found. Relevant to GetObject and DeleteObject operations.

func (*GCSObjectClient) List

func (s *GCSObjectClient) List(ctx context.Context, prefix, delimiter string) ([]chunk.StorageObject, []chunk.StorageCommonPrefix, error)

List implements chunk.ObjectClient.
