The Flink Kafka Consumer participates in checkpointing and guarantees that no data is lost - * during a failure, and that the computation processes elements "exactly once". - * (Note: These guarantees naturally assume that Kafka itself does not loose any data.)

- * - *

To support a variety of Kafka brokers, protocol versions, and offset committing approaches, - * the Flink Kafka Consumer can be parametrized with a fetcher and an offset handler.

- * - *

Fetcher

- * - *

The fetcher is responsible to pull data from Kafka. Because Kafka has undergone a change in - * protocols and APIs, there are currently two fetchers available:

- * - *
    - *
  • {@link FetcherType#NEW_HIGH_LEVEL}: A fetcher based on the new Kafka consumer API. - * This fetcher is generally more robust, but works only with later versions of - * Kafka (> 0.8.2).
    • - * - *
  • {@link FetcherType#LEGACY_LOW_LEVEL}: A fetcher based on the old low-level consumer API. - * This fetcher is works also with older versions of Kafka (0.8.1). The fetcher interprets - * the old Kafka consumer properties, like: - *
      - *
    • socket.timeout.ms
      • - *
    • socket.receive.buffer.bytes
      • - *
    • fetch.message.max.bytes
      • - *
    • auto.offset.reset with the values "latest", "earliest" (unlike 0.8.2 behavior)
      • - *
    • fetch.wait.max.ms
      • - *
    - *
    • - *
- * - *

Offset handler

- * - *

Offsets whose records have been read and are checkpointed will be committed back to Kafka / ZooKeeper - * by the offset handler. In addition, the offset handler finds the point where the source initially - * starts reading from the stream, when the streaming job is started.

- * - *

Currently, the source offers two different offset handlers exist:

- *
    - *
  • {@link OffsetStore#KAFKA}: Use this offset handler when the Kafka brokers are managing the offsets, - * and hence offsets need to be committed the Kafka brokers, rather than to ZooKeeper. - * Note that this offset handler works only on new versions of Kafka (0.8.2.x +) and - * with the {@link FetcherType#NEW_HIGH_LEVEL} fetcher.
    • - * - *
  • {@link OffsetStore#FLINK_ZOOKEEPER}: Use this offset handler when the offsets are managed - * by ZooKeeper, as in older versions of Kafka (0.8.1.x)
    • - *
- * - *

Please note that Flink snapshots the offsets internally as part of its distributed checkpoints. The offsets - * committed to Kafka / ZooKeeper are only to bring the outside view of progress in sync with Flink's view - * of the progress. That way, monitoring and other jobs can get a view of how far the Flink Kafka consumer - * has consumed a topic.

- * - *

NOTE: The implementation currently accesses partition metadata when the consumer - * is constructed. That means that the client that submits the program needs to be able to - * reach the Kafka brokers or ZooKeeper.
