type NetworkDB 

type NetworkDB struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

NetworkDB instance drives the networkdb cluster and acts the broker for cluster-scoped and network-scoped gossip and watches.

func New 

func New(c *Config) (*NetworkDB, error)

New creates a new instance of NetworkDB using the Config passed by the caller.

func (*NetworkDB) Close 

func (nDB *NetworkDB) Close()

Close destroys this NetworkDB instance by leave the cluster, stopping timers, canceling goroutines etc.

func (*NetworkDB) ClusterPeers 

func (nDB *NetworkDB) ClusterPeers() []PeerInfo

ClusterPeers returns all the gossip cluster peers.

func (*NetworkDB) CreateEntry 

func (nDB *NetworkDB) CreateEntry(tname, nid, key string, value []byte) error

CreateEntry creates a table entry in NetworkDB for given (network, table, key) tuple and if the NetworkDB is part of the cluster propagates this event to the cluster. It is an error to create an entry for the same tuple for which there is already an existing entry unless the current entry is deleting state.

func (*NetworkDB) DeleteEntry 

func (nDB *NetworkDB) DeleteEntry(tname, nid, key string) error

DeleteEntry deletes a table entry in NetworkDB for given (network, table, key) tuple and if the NetworkDB is part of the cluster propagates this event to the cluster.

func (*NetworkDB) JoinNetwork 

func (nDB *NetworkDB) JoinNetwork(nid string) error

JoinNetwork joins this node to a given network and propagates this event across the cluster. This triggers this node joining the sub-cluster of this network and participates in the network-scoped gossip and bulk sync for this network.

func (*NetworkDB) LeaveNetwork 

func (nDB *NetworkDB) LeaveNetwork(nid string) error

LeaveNetwork leaves this node from a given network and propagates this event across the cluster. This triggers this node leaving the sub-cluster of this network and as a result will no longer participate in the network-scoped gossip and bulk sync for this network. Also remove all the table entries for this network from networkdb

func (*NetworkDB) Peers 

func (nDB *NetworkDB) Peers(nid string) []PeerInfo

Peers returns the gossip peers for a given network.

func (*NetworkDB) RegisterDiagnosticHandlers 

func (nDB *NetworkDB) RegisterDiagnosticHandlers(m Mux)

func (*NetworkDB) RemoveKey 

func (nDB *NetworkDB) RemoveKey(key []byte)

RemoveKey removes a key from the key ring. The key being removed can't be the primary key

func (nDB *NetworkDB) SetKey(key []byte)

SetKey adds a new key to the key ring

func (*NetworkDB) SetPrimaryKey 

func (nDB *NetworkDB) SetPrimaryKey(key []byte)

SetPrimaryKey sets the given key as the primary key. This should have been added apriori through SetKey

func (*NetworkDB) UpdateEntry 

func (nDB *NetworkDB) UpdateEntry(tname, nid, key string, value []byte) error

UpdateEntry updates a table entry in NetworkDB for given (network, table, key) tuple and if the NetworkDB is part of the cluster propagates this event to the cluster. It is an error to update a non-existent entry.

func (*NetworkDB) WalkTable 

func (nDB *NetworkDB) WalkTable(tname string, fn func(string, string, []byte, bool) bool) error

WalkTable walks a single table in NetworkDB and invokes the passed function for each entry in the table passing the network, key, value. The walk stops if the passed function returns a true.

func (*NetworkDB) Watch 

func (nDB *NetworkDB) Watch(tname, nid string) (*events.Channel, func())

Watch creates a watcher with filters for a particular table or network or any combination of the tuple. If any of the filter is an empty string it acts as a wildcard for that field. Watch returns a channel of events, where the events will be sent.

type NetworkEntry 

type NetworkEntry struct {
	// ID of the network
	NetworkID string `protobuf:"bytes,1,opt,name=network_id,json=networkId,proto3" json:"network_id,omitempty"`
	// Latest lamport time of the network attachment when this
	// network event was recorded.
	LTime github_com_hashicorp_serf_serf.LamportTime `protobuf:"varint,2,opt,name=l_time,json=lTime,proto3,customtype=github.com/hashicorp/serf/serf.LamportTime" json:"l_time"`
	// Source node name where this network attachment happened.
