Parameters:

streamIds - the stream ids.

Returns:

the builder.

setStreamPattern

public DynamicKafkaSourceBuilder<T> setStreamPattern(Pattern streamPattern)

Set the stream pattern to determine stream ids belonging to the KafkaMetadataService.

Parameters:

streamPattern - the stream pattern.

Returns:

the builder.

setKafkaStreamSubscriber

public DynamicKafkaSourceBuilder<T> setKafkaStreamSubscriber(KafkaStreamSubscriber kafkaStreamSubscriber)

Set a custom Kafka stream subscriber.

Parameters:

kafkaStreamSubscriber - the KafkaStreamSubscriber.

Returns:

the builder.

setBounded

public DynamicKafkaSourceBuilder<T> setBounded(OffsetsInitializer stoppingOffsetsInitializer)

Set the source in bounded mode and specify what offsets to end at. This is used for all clusters.

Parameters:

stoppingOffsetsInitializer - the OffsetsInitializer.

Returns:

the builder.

setKafkaMetadataService

public DynamicKafkaSourceBuilder<T> setKafkaMetadataService(KafkaMetadataService kafkaMetadataService)
