}

func (*CustomHeader) Marshal

func (h *CustomHeader) Marshal() []byte

type CustomRaftLog

type CustomRaftLog struct {
	Data []byte
	// contains filtered or unexported fields
}

CustomRaftLog is the raft log format for unistore to store Prewrite/Commit/PessimisticLock.

| flag(1) | type(1) | version(2) | header(40) | entries

It reduces the cost of marshal/unmarshal and avoid DB lookup during apply.
