Types

type BadgerStore

type BadgerStore struct{}

BadgerStore provides access to Badger for Raft to store and retrieve log entries. It also provides key/value storage, and can be used as a LogStore and StableStore.

func (*BadgerStore) DeleteRange

func (b *BadgerStore) DeleteRange(min, max uint64) error

DeleteRange deletes logs within a given range inclusively.

func (*BadgerStore) FirstIndex

func (b *BadgerStore) FirstIndex() (uint64, error)

FirstIndex returns the first known index from the Raft log.

func (*BadgerStore) Get

func (b *BadgerStore) Get(key []byte) ([]byte, error)

Get is used to retrieve a value from the k/v store by key

func (*BadgerStore) GetLog

func (b *BadgerStore) GetLog(index uint64, log *raft.Log) error

GetLog gets a log entry from Badger at a given index.

func (*BadgerStore) GetUint64

func (b *BadgerStore) GetUint64(key []byte) (uint64, error)

GetUint64 is like Get, but handles uint64 values

func (*BadgerStore) LastIndex

func (b *BadgerStore) LastIndex() (uint64, error)

LastIndex returns the last known index from the Raft log.

func (*BadgerStore) Set

func (b *BadgerStore) Set(key []byte, val []byte) error

Set is used to set a key/value set outside of the raft log.

func (*BadgerStore) SetUint64

func (b *BadgerStore) SetUint64(key []byte, val uint64) error

SetUint64 is like Set, but handles uint64 values

func (*BadgerStore) StoreLog

func (b *BadgerStore) StoreLog(log *raft.Log) error

StoreLog stores a single raft log.

func (*BadgerStore) StoreLogs

func (b *BadgerStore) StoreLogs(logs []*raft.Log) error

StoreLogs stores a set of raft logs.

	cluster.ReplicaMessageHandler
	// contains filtered or unexported fields
