Types

type BrokerServiceClient 

type BrokerServiceClient interface {
	RemoveResource(
		ctx context.Context,
		WorkerID frameModel.WorkerID,
		resourceID resModel.ResourceID,
	) error
}

BrokerServiceClient wraps a pb.BrokerServiceClient

func NewBrokerServiceClient 

func NewBrokerServiceClient(cli enginepb.BrokerServiceClient) BrokerServiceClient

NewBrokerServiceClient returns a new BrokerServiceClient.

type DefaultExecutorGroup 

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

DefaultExecutorGroup is the default implementation for ExecutorGroup.

func NewExecutorGroup 

func NewExecutorGroup(
	credentials *security.Credential,
	logger *zap.Logger,
) *DefaultExecutorGroup

NewExecutorGroup creates a new ExecutorGroup.

func (*DefaultExecutorGroup) AddExecutor 

func (g *DefaultExecutorGroup) AddExecutor(executorID model.ExecutorID, addr string) error

AddExecutor adds an executor to the executor group. A new ExecutorClient will be created by this method. Note that since we are using asynchronous Dial, this method usually does not fail even if a bad address is provided.

func (*DefaultExecutorGroup) GetExecutorClient 

func (g *DefaultExecutorGroup) GetExecutorClient(id model.ExecutorID) (ExecutorClient, bool)

GetExecutorClient tries to get the ExecutorClient for the given executor.

func (*DefaultExecutorGroup) GetExecutorClientB 

func (g *DefaultExecutorGroup) GetExecutorClientB(ctx context.Context, id model.ExecutorID) (ExecutorClient, error)

GetExecutorClientB tries to get the ExecutorClient for the given executor. It blocks until either the context has been canceled or the executor ID becomes valid.

When an Executor goes offline, the ID is added to a tombstone list so that we can fail fast. The assumption here is that executor IDs will not be reused.

func (*DefaultExecutorGroup) RemoveExecutor 

func (g *DefaultExecutorGroup) RemoveExecutor(executorID model.ExecutorID) error

RemoveExecutor removes an executor from the group. Note that the ExecutorClient maintained will be closed.

func (*DefaultExecutorGroup) UpdateExecutorList 

func (g *DefaultExecutorGroup) UpdateExecutorList(executors map[model.ExecutorID]string) error

UpdateExecutorList updates the stored clients using a map from executor IDs to their addresses. Note: This method will not wait for the clients to be fully connected. In the rare case where grpc.Dial does fail, an error will be returned to the caller of this method, and the caller should retry appropriately.

type DiscoveryClient 

type DiscoveryClient interface {
	// RegisterExecutor registers an executor. The server
	// will allocate and records a UUID.
	RegisterExecutor(
		ctx context.Context,
		request *pb.RegisterExecutorRequest,
	) (model.ExecutorID, error)

	// ListExecutors lists all executors.
	ListExecutors(ctx context.Context) ([]*pb.Executor, error)

	// ListMasters lists all masters.
	ListMasters(ctx context.Context) ([]*pb.Master, error)

	// Heartbeat sends a heartbeat message to the server.
	Heartbeat(
		ctx context.Context,
		request *pb.HeartbeatRequest,
	) (*pb.HeartbeatResponse, error)

	// QueryMetaStore queries the details of a metastore.
	QueryMetaStore(
		ctx context.Context,
		request *pb.QueryMetaStoreRequest,
	) (*pb.QueryMetaStoreResponse, error)

	// QueryStorageConfig queries the storage config.
	QueryStorageConfig(
		ctx context.Context,
		in *pb.QueryStorageConfigRequest,
	) (*pb.QueryStorageConfigResponse, error)
}

DiscoveryClient is a client to the Discovery service on the server master.

func NewDiscoveryClient 

func NewDiscoveryClient(cli pb.DiscoveryClient) DiscoveryClient

NewDiscoveryClient returns a DiscoveryClient.

type DispatchTaskArgs 

type DispatchTaskArgs struct {
	ProjectInfo  tenant.ProjectInfo
	WorkerID     string
	MasterID     string
	WorkerType   int64
	WorkerConfig []byte
	WorkerEpoch  int64
}

DispatchTaskArgs contains the required parameters for creating a worker.

type ExecutorClient 

type ExecutorClient interface {
	ExecutorServiceClient
	BrokerServiceClient

	// Close closes the gRPC connection used to create the client.
	Close()
}

ExecutorClient is the public interface for an executor client. It is only for one executor. For a client to a group of executors, refer to ExecutorGroup.

func NewExecutorClient 

func NewExecutorClient(conn *grpc.ClientConn) ExecutorClient

NewExecutorClient creates a new executor client. Note that conn will be closed if the returned client is closed.

type ExecutorGroup 

type ExecutorGroup interface {
	// GetExecutorClient tries to get the ExecutorClient for the given executor.
	// It will return (nil, false) immediately if no such executor is found.
	GetExecutorClient(id model.ExecutorID) (ExecutorClient, bool)

	// GetExecutorClientB tries to get the ExecutorClient for the given executor.
	// It blocks until either the context has been canceled or the executor ID becomes valid.
	GetExecutorClientB(ctx context.Context, id model.ExecutorID) (ExecutorClient, error)
}

ExecutorGroup holds a group of ExecutorClients. It is used by any component that would like to invoke RPC methods on the executors.

type ExecutorServiceClient 

type ExecutorServiceClient interface {
	DispatchTask(
		ctx context.Context,
		args *DispatchTaskArgs,
		startWorkerTimer StartWorkerCallback,
	) error
}

ExecutorServiceClient wraps a pb.ExecutorServiceClient and provides a DispatchTask method, which will call PreDispatchTask and ConfirmDispatchTask. TODO The service called "Executor" should be renamed "Dispatch", so that we have separate services for two sets of functionalities, i.e., dispatching tasks and managing resources (broker service).

func NewExecutorServiceClient 

func NewExecutorServiceClient(cli pb.ExecutorServiceClient) ExecutorServiceClient

NewExecutorServiceClient creates a new ExecutorServiceClient.
