Instance Constructors

  1. new KafkaContinuousStream(offsetReader: KafkaOffsetReader, kafkaParams: Map[String, AnyRef], options: CaseInsensitiveStringMap, metadataPath: String, initialOffsets: KafkaOffsetRangeLimit, failOnDataLoss: Boolean)

    offsetReader

    a reader used to get kafka offsets. Note that the actual data will be read by per-task consumers generated later.

    kafkaParams

    String params for per-task Kafka consumers.

    options

    Params which are not Kafka consumer params.

    metadataPath

    Path to a directory this reader can use for writing metadata.

    initialOffsets

    The Kafka offsets to start reading data at.

    failOnDataLoss

    Flag indicating whether reading should fail in data loss scenarios, where some offsets after the specified initial ones can't be properly read.
