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 TestNewLogClient added in v0.14.0 

func TestNewLogClient(t *testing.T, rpcClient snpb.LogIOClient, target varlogpb.StorageNode) *LogClient

func (*LogClient) Append 

func (c *LogClient) Append(ctx context.Context, tpid types.TopicID, lsid types.LogStreamID, data [][]byte) ([]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) AppendStream added in v0.14.0 

func (c *LogClient) AppendStream(ctx context.Context) (snpb.LogIO_AppendClient, error)

func (*LogClient) LogStreamReplicaMetadata added in v0.4.1

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) 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 (*ManagementClient) Unseal 

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

type Manager
