Types

type ResultFileDB

type ResultFileDB struct {
	sync.Mutex
	// contains filtered or unexported fields
}

ResultFileDB provider a implementation of `historydb.HistoryDB` This implementation provides a key-value based data model

func NewResultFileDB

func NewResultFileDB(chainId string, handle protocol.DBHandle, logger protocol.Logger,
	storeConfig *conf.StorageConfig, fileDB binlog.BinLogger) *ResultFileDB

func (*ResultFileDB) Close

func (h *ResultFileDB) Close()

Close is used to close database

func (*ResultFileDB) CommitBlock

func (h *ResultFileDB) CommitBlock(blockInfo *serialization.BlockWithSerializedInfo, isCache bool) error

CommitBlock commits the block rwsets in an atomic operation

func (*ResultFileDB) GetLastSavepoint

func (h *ResultFileDB) GetLastSavepoint() (uint64, error)

GetLastSavepoint returns the last block height

func (*ResultFileDB) GetRWSetIndex

func (h *ResultFileDB) GetRWSetIndex(txId string) (*storePb.StoreInfo, error)

GetRWSetIndex returns the offset of the block in the file

func (*ResultFileDB) GetTxRWSet

func (h *ResultFileDB) GetTxRWSet(txId string) (*commonPb.TxRWSet, error)

GetTxRWSet returns an txRWSet for given txId, or returns nil if none exists.

func (*ResultFileDB) InitGenesis

func (h *ResultFileDB) InitGenesis(genesisBlock *serialization.BlockWithSerializedInfo) error

func (*ResultFileDB) RestoreBlocks

func (h *ResultFileDB) RestoreBlocks(blockInfos []*serialization.BlockWithSerializedInfo) error

func (*ResultFileDB) ShrinkBlocks

func (h *ResultFileDB) ShrinkBlocks(txIdsMap map[uint64][]string) error

ShrinkBlocks archive old blocks rwsets in an atomic operation
