Types

type KVStore

type KVStore struct {
	*base.KV
	// contains filtered or unexported fields
}

KVStore is a key-value store backed by raft

func (*KVStore) DelByNode

func (s *KVStore) DelByNode(node string) int

func (*KVStore) GetErrorC

func (s *KVStore) GetErrorC(key, value string) <-chan error

func (*KVStore) Lookup

func (s *KVStore) Lookup(key string) []string

type Peer

type Peer struct {
	// contains filtered or unexported fields
}

func Setup

func Setup(conf *config.Cluster, notifyCh chan<- *message.Message) (*Peer, error)

Setup initiates a raft instance and returns a committed log entry channel and error channel. Proposals for log updates are sent over the provided the proposal channel. All log entries are replayed over the commit channel, followed by a nil message (to indicate the channel is current), then new log entries. To shutdown, close proposeC and read errorC.
