Types

type Kind 

type Kind interface {
	*LogClient | *ManagementClient

	// Target returns target storage node.
	Target() varlogpb.StorageNode
	// contains filtered or unexported methods
}

Kind is a generic type for clients managed by the Manager.

type LogClient 

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

func (*LogClient) Append 

func (c *LogClient) Append(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID, data [][]byte, backups ...varlogpb.StorageNode) ([]snpb.AppendResult, error)

Append stores data to the log stream specified with the topicID and the logStreamID. The backup indicates the storage nodes that have backup replicas of that log stream. It returns valid GLSN if the append completes successfully.

func (*LogClient) LogStreamMetadata 

func (c *LogClient) LogStreamMetadata(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID) (varlogpb.LogStreamDescriptor, error)

func (*LogClient) Subscribe 

func (c *LogClient) Subscribe(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID, begin, end types.GLSN) (<-chan SubscribeResult, error)

Subscribe gets log entries continuously from the storage node. It guarantees that LLSNs of log entries taken are sequential.

func (*LogClient) SubscribeTo 

func (c *LogClient) SubscribeTo(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID, begin, end types.LLSN) (<-chan SubscribeResult, error)

Target returns connected storage node.

func (*LogClient) TrimDeprecated 

func (c *LogClient) TrimDeprecated(ctx context.Context, tpid types.TopicID, glsn types.GLSN) error

TrimDeprecated deletes log entries greater than or equal to given GLSN in the storage node. The number of deleted log entries are returned.

type ManagementClient 

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

func (*ManagementClient) Target 

func (c *ManagementClient) Target() varlogpb.StorageNode

func (*ManagementClient) Trim 

func (c *ManagementClient) Trim(ctx context.Context, topicID types.TopicID, lastGLSN types.GLSN) (map[types.LogStreamID]error, error)

func (c *ManagementClient) Unseal(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID, replicas []varlogpb.LogStreamReplica) error

type Manager 

type Manager[T Kind] struct {
	// contains filtered or unexported fields
}

Manager manages clients typed Kind.

func NewManager 

func NewManager[T Kind](opts ...ManagerOption) (*Manager[T], error)

NewManager creates a Manager.

func (*Manager[T]) Close 

func (mgr *Manager[T]) Close() (err error)

Close closes all clients managed by the Manager.

func (*Manager[T]) CloseClient 

func (mgr *Manager[T]) CloseClient(snid types.StorageNodeID) error

CloseClient closes a client identified by the argument snid.

func (*Manager[T]) Get 

func (mgr *Manager[T]) Get(snid types.StorageNodeID) (T, error)

Get returns the client identified by the argument snid. It returns an error if the client does not exist.

func (*Manager[T]) GetByAddress

func (*Manager[T]) GetOrConnect 

func (mgr *Manager[T]) GetOrConnect(ctx context.Context, snid types.StorageNodeID, addr string) (T, error)

GetOrConnect returns the client identified by the argument snid. It tries to connect the server using the argument addr if the client does not exist. It returns an error if the existing client has an address other than the argument addr or trial of the connection fails.

type ManagerOption 

type ManagerOption interface {
