	ShrinkBlocks(txIdsMap map[uint64][]string) error

	// RestoreBlocks restore blocks from outside serialized block data
	RestoreBlocks(blockInfos []*serialization.BlockWithSerializedInfo) error

	// GetTxRWSet returns an txRWSet for given txId, or returns nil if none exists.
	GetTxRWSet(txid string) (*commonPb.TxRWSet, error)

	// GetRWSetIndex returns the offset of the rwset in the file
	GetRWSetIndex(txId string) (*storePb.StoreInfo, error)

	// GetLastSavepoint returns the last block height
