Types

type TaskNode

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

TaskNode as background min execution unit, execute storage provider's background tasks implements the gRPC of TaskNodeService, TODO :: TaskNode support more task types, such as gc etc.

func NewTaskNodeService

func NewTaskNodeService(cfg *TaskNodeConfig) (*TaskNode, error)

NewTaskNodeService return an instance of TaskNode and init resource

func (*TaskNode) Name

func (taskNode *TaskNode) Name() string

Name return the task node service name, for the lifecycle management

func (*TaskNode) QueryReplicatingObject

func (taskNode *TaskNode) QueryReplicatingObject(ctx context.Context, req *types.QueryReplicatingObjectRequest) (
	resp *types.QueryReplicatingObjectResponse, err error)

QueryReplicatingObject query a replicating object information by object id

func (*TaskNode) ReplicateObject

func (taskNode *TaskNode) ReplicateObject(ctx context.Context, req *types.ReplicateObjectRequest) (
	*types.ReplicateObjectResponse, error)

ReplicateObject call AsyncReplicateObject non-blocking upstream services

func (*TaskNode) Start

func (taskNode *TaskNode) Start(ctx context.Context) error

Start the task node gRPC service and background tasks

func (*TaskNode) Stop

func (taskNode *TaskNode) Stop(ctx context.Context) error

type TaskNodeConfig

type TaskNodeConfig struct {
	SpOperatorAddress string
	GRPCAddress       string
	SignerGrpcAddress string
	P2PGrpcAddress    string
	SpDBConfig        *config.SQLDBConfig
