Functions

func AllUsers 

func AllUsers(_ string) (bool, error)

AllUsers returns true to each call and should be used whenever the UsersScanner should not filter out any user due to sharding.

func CreateCachingBucket 

func CreateCachingBucket(chunksConfig ChunksCacheConfig, metadataConfig MetadataCacheConfig, bkt objstore.Bucket, logger log.Logger, reg prometheus.Registerer) (objstore.Bucket, error)

func HashBlockID 

func HashBlockID(id ulid.ULID) uint32

HashBlockID returns a 32-bit hash of the block ID useful for ring-based sharding.

func NewIndexCache 

func NewIndexCache(cfg IndexCacheConfig, logger log.Logger, registerer prometheus.Registerer) (storecache.IndexCache, error)

NewIndexCache creates a new index cache based on the input configuration.

func TenantDeletionMarkExists 

func TenantDeletionMarkExists(ctx context.Context, bkt objstore.BucketReader, userID string) (bool, error)

Checks for deletion mark for tenant. Errors other than "object not found" are returned.
