Functions ¶
func NewRecordProcessorCheckpoint ¶
func NewRecordProcessorCheckpoint(shard *par.ShardStatus, checkpoint chk.Checkpointer) kcl.IRecordProcessorCheckpointer
Types ¶
type FanOutShardConsumer ¶
type FanOutShardConsumer struct {
// contains filtered or unexported fields
}
FanOutShardConsumer is responsible for consuming data records of a (specified) shard. Note: FanOutShardConsumer only deal with one shard. For more info see: https://docs.aws.amazon.com/streams/latest/dev/enhanced-consumers.html
type PollingShardConsumer ¶
type PollingShardConsumer struct {
// contains filtered or unexported fields
}
PollingShardConsumer is responsible for polling data records from a (specified) shard. Note: PollingShardConsumer only deal with one shard.
type PreparedCheckpointer ¶
type PreparedCheckpointer struct {
// contains filtered or unexported fields
}
Objects of this class are prepared to checkpoint at a specific sequence number. They use an * IRecordProcessorCheckpointer to do the actual checkpointing, so their checkpoint is subject to the same 'didn't go * backwards' validation as a normal checkpoint.
func (*PreparedCheckpointer) Checkpoint ¶
func (pc *PreparedCheckpointer) Checkpoint() error
func (*PreparedCheckpointer) GetPendingCheckpoint ¶
func (pc *PreparedCheckpointer) GetPendingCheckpoint() *kcl.ExtendedSequenceNumber
type RecordProcessorCheckpointer ¶
type RecordProcessorCheckpointer struct {
// contains filtered or unexported fields
}
*
- This class is used to enable RecordProcessors to checkpoint their progress.
- The Amazon Kinesis Client Library will instantiate an object and provide a reference to the application
- RecordProcessor instance. Amazon Kinesis Client Library will create one instance per shard assignment.
func (*RecordProcessorCheckpointer) Checkpoint ¶
func (rc *RecordProcessorCheckpointer) Checkpoint(sequenceNumber *string) error
func (*RecordProcessorCheckpointer) PrepareCheckpoint ¶
func (rc *RecordProcessorCheckpointer) PrepareCheckpoint(sequenceNumber *string) (kcl.IPreparedCheckpointer, error)
type Worker ¶
type Worker struct {
// contains filtered or unexported fields
}
Worker is the high level class that Kinesis applications use to start processing data. It initializes and oversees different components (e.g. syncing shard and lease information, tracking shard assignments, and processing data from the shards).
func NewWorker ¶
func NewWorker(factory kcl.IRecordProcessorFactory, kclConfig *config.KinesisClientLibConfiguration) *Worker
NewWorker constructs a Worker instance for processing Kinesis stream data.
func (*Worker) Shutdown ¶
func (w *Worker) Shutdown()
Shutdown signals worker to shutdown. Worker will try initiating shutdown of all record processors.
func (*Worker) Start ¶
Run starts consuming data from the stream, and pass it to the application record processors.
func (*Worker) WithCheckpointer ¶
func (w *Worker) WithCheckpointer(checker chk.Checkpointer) *Worker
WithCheckpointer is used to provide a custom checkpointer service for non-dynamodb implementation or unit testing.
func (*Worker) WithKinesis ¶
func (w *Worker) WithKinesis(svc kinesisiface.KinesisAPI) *Worker
WithKinesis is used to provide Kinesis service for either custom implementation or unit testing.
