Abstract Value Members

  1. abstract def position(partition: TopicPartition, timeout: FiniteDuration): F[Long]

    Returns the offset of the next record that will be fetched.

  2. abstract def position(partition: TopicPartition): F[Long]

    Returns the offset of the next record that will be fetched.

    Timeout is determined by default.api.timeout.ms, which is set using ConsumerSettings#withDefaultApiTimeout.

  3. abstract def seek(partition: TopicPartition, offset: Long): F[Unit]

    Overrides the fetch offsets that the consumer will use when reading the next record.

    Overrides the fetch offsets that the consumer will use when reading the next record. If this API is invoked for the same partition more than once, the latest offset will be used. Note that you may lose data if this API is arbitrarily used in the middle of consumption to reset the fetch offsets.

  4. abstract def seekToBeginning[G[_]](partitions: G[TopicPartition])(implicit arg0: Foldable[G]): F[Unit]

    Seeks to the first offset for each of the specified partitions.

    Seeks to the first offset for each of the specified partitions. If no partitions are provided, seeks to the first offset for all currently assigned partitions.

    Note that this seek evaluates lazily, and only on the next call to poll or position.

  5. abstract def seekToBeginning: F[Unit]

    Seeks to the first offset for each currently assigned partition.

    Seeks to the first offset for each currently assigned partition. This is equivalent to using seekToBeginning with an empty set of partitions.

    Note that this seek evaluates lazily, and only on the next call to poll or position.

  6. abstract def seekToEnd[G[_]](partitions: G[TopicPartition])(implicit arg0: Foldable[G]): F[Unit]

    Seeks to the last offset for each of the specified partitions.

    Seeks to the last offset for each of the specified partitions. If no partitions are provided, seeks to the last offset for all currently assigned partitions.

    Note that this seek evaluates lazily, and only on the next call to poll or position.

  7. abstract def seekToEnd: F[Unit]

    Seeks to the last offset for each currently assigned partition.

    Seeks to the last offset for each currently assigned partition. This is equivalent to using seekToEnd with an empty set of partitions.

    Note that this seek evaluates lazily, and only on the next call to poll or position.
