Functions

func NewBatchedLogDB

func NewBatchedLogDB(dirs []string, lldirs []string) (raftio.ILogDB, error)

NewBatchedLogDB is the factory function for creating LevelDB based Log DB instances. Raft entries are batched before they get stored into LevelDB, it uses more memory and provides better throughput performance.

Deprecated: please use the default RocksDB based LogDB.

func NewLogDB

func NewLogDB(dirs []string, lldirs []string) (raftio.ILogDB, error)

NewLogDB is the factory function for creating LevelDB based Log DB instances. Raft entries are stored in its plain format, it uses less memory than the batched alternative implementation but comes at the cost of lower throughput.

Deprecated: please use the default RocksDB based LogDB.
