Functions

func NewMessageServer 

func NewMessageServer(
	selfID NodeID,
	_credential *security.Credential,
	opts ...MessageServerOpt,
) *p2pImpl.MessageServer

NewMessageServer creates a new message server from given configs

Types

type Config 

type Config = p2pImpl.MessageServerConfig

Config alias to p2pImpl.MessageServerConfig

type HandlerFunc 

type HandlerFunc = func(sender NodeID, value MessageValue) error

HandlerFunc alias to message handler function

type MessageHandlerManager 

type MessageHandlerManager interface {
	RegisterHandler(ctx context.Context, topic Topic, tpi TypeInformation, fn HandlerFunc) (bool, error)
	UnregisterHandler(ctx context.Context, topic Topic) (bool, error)
	CheckError(ctx context.Context) error

	// Clean unregisters all existing handlers.
	Clean(ctx context.Context) error

	// SetTimeout sets the timeout for handler operations.
	// A timeout is needed because the underlying handler operations are
	// asynchronous in the MessageServer.
	SetTimeout(timeout time.Duration)
}

MessageHandlerManager is for managing message topic handlers. NOTE: for each topic, only one handler is allowed.

type MessageRPCService 

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

MessageRPCService is a background service wrapping a MessageServer instance.

func NewDependentMessageRPCService 

func NewDependentMessageRPCService(
	selfID NodeID,
	_credential *security.Credential,
	grpcSvr *grpc.Server,
	opts ...MessageServerOpt,
) (*MessageRPCService, error)

NewDependentMessageRPCService creates a new MessageRPCService that DOES NOT own a `grpc.Server`. TODO refactor the design.

func NewMessageRPCService 

func NewMessageRPCService(
	selfID NodeID,
	_credential *security.Credential,
	opts ...MessageServerOpt,
) (*MessageRPCService, error)

func NewMessageRPCServiceWithRPCServer 

func NewMessageRPCServiceWithRPCServer(
	selfID NodeID,
	_credential *security.Credential,
	grpcSvr *grpc.Server,
	opts ...MessageServerOpt,
) *MessageRPCService

NewMessageRPCServiceWithRPCServer creates a new MessageRPCService with an existing gRPC server.

func NewMessageRouter 

func NewMessageRouter(nodeID NodeID, advertisedAddr string) MessageRouter

NewMessageRouter creates a new MessageRouter instance via tiflow p2p API

type MessageSender 

type MessageSender interface {

	// SendToNode sends a message to a given node. Returns whether it is successful and a possible error.
	// A `would-block` error will not be returned. (false, nil) would be returned instead.
	SendToNode(ctx context.Context, targetNodeID NodeID, topic Topic, message interface{}) (bool, error)

	// SendToNodeB sends a message to a given node in a blocking way
	SendToNodeB(ctx context.Context, targetNodeID NodeID, topic Topic, message interface{}) error
}

MessageSender is used to send a message of a given topic to a given node.

func NewMessageSender 

func NewMessageSender(router MessageRouter) MessageSender

NewMessageSender returns a new message sender.
