Types

type ShardSelector

type ShardSelector struct {
	// contains filtered or unexported fields

ShardSelector is used by the dagstore's index-backed blockstore to select the best shard from which to retrieve a particular cid. It chooses the first shard that is unsealed and free (zero cost). It caches the results per-shard.

func NewShardSelector

func NewShardSelector(ctx context.Context, ps piecestore.PieceStore, sa retrievalmarket.SectorAccessor, rp retrievalmarket.RetrievalProvider) (*ShardSelector, error)

func (*ShardSelector) ShardSelectorF

func (s *ShardSelector) ShardSelectorF(c cid.Cid, shards []shard.Key) (shard.Key, error)
