Functions

func NewBucketClient 

func NewBucketClient(storageConfig Config) (chunk.BucketClient, error)

NewBucketClient makes a new bucket client based on the configuration.

func NewChunkClient 

func NewChunkClient(name string, cfg Config, schemaCfg chunk.SchemaConfig, registerer prometheus.Registerer) (chunk.Client, error)

NewChunkClient makes a new chunk.Client of the desired types.

func NewIndexClient 

func NewIndexClient(name string, cfg Config, schemaCfg chunk.SchemaConfig, registerer prometheus.Registerer) (chunk.IndexClient, error)

NewIndexClient makes a new index client of the desired type.

func NewObjectClient 

func NewObjectClient(name string, cfg Config) (chunk.ObjectClient, error)

NewObjectClient makes a new StorageClient of the desired types.

func NewStore 

func NewStore(
	cfg Config,
	storeCfg chunk.StoreConfig,
	schemaCfg chunk.SchemaConfig,
	limits StoreLimits,
	reg prometheus.Registerer,
	cacheGenNumLoader chunk.CacheGenNumLoader,
	logger log.Logger,
) (chunk.Store, error)

NewStore makes the storage clients based on the configuration.

func NewTableClient 

func NewTableClient(name string, cfg Config, registerer prometheus.Registerer) (chunk.TableClient, error)
