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) LogStreamReplicaMetadata added in v0.4.1

func (c *LogClient) LogStreamReplicaMetadata(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID) (snpb.LogStreamReplicaMetadataDescriptor, 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)

func (*LogClient) Target

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

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) AddLogStreamReplica

func (*ManagementClient) Close

func (c *ManagementClient) Close() error

Close closes connection to the storage node. Deprecated: Use `Manager[*ManagementClient]`.

func (*ManagementClient) GetMetadata

func (*ManagementClient) RemoveLogStream

func (c *ManagementClient) RemoveLogStream(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID) error

func (*ManagementClient) Seal

func (c *ManagementClient) Seal(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID, lastCommittedGLSN types.GLSN) (varlogpb.LogStreamStatus, types.GLSN, error)

func (*ManagementClient) Sync

func (c *ManagementClient) Sync(ctx context.Context, tpid types.TopicID, logStreamID types.LogStreamID, backupStorageNodeID types.StorageNodeID, backupAddress string, lastGLSN types.GLSN) (*snpb.SyncStatus, error)

func (*ManagementClient) Target

func (*ManagementClient) Trim

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

func (*ManagementClient) Unseal

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 (mgr *Manager[T]) GetByAddress(addr string) (T, error)

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 {
	// contains filtered or unexported methods
}

func WithClusterID

func WithClusterID(cid types.ClusterID) ManagerOption

func WithDefaultGRPCDialOptions

func WithDefaultGRPCDialOptions(defaultGRPCDialOptions ...grpc.DialOption) ManagerOption

func WithLogger

func WithLogger(logger *zap.Logger) ManagerOption
