So, in this article, we will learn the whole concept of Spark Streaming Integration in Kafka in detail. When Kafka does log compaction offsets often end up with gaps, meaning the next requested offset will be frequently not be offset+1. The logic in KafkaRDD & CachedKafkaConsumer has a baked in assumption that the next offset will always be just an increment of 1 above the previous offset.

    Kafka tutorial #8 - Spark Structured Streaming

    Support for Kafka in Spark has never been great - especially as regards to offset management - and the fact that the connector still relies on Kafka 0.10 is a concern. The deployment model - and the impact it has on how you upgrade applications - is complex, especially in comparison with what Kafka Streams has to offer. For onStart, Assign creates a KafkaConsumer (with kafkaParams) and explicitly assigns the list of partitions topicPartitions to this consumer (using Kafka’s KafkaConsumer.assign method). It then overrides the fetch offsets that the consumer will use (on the next poll) to onStart's input currentOffsets or offsets whatever is not empty (using Kafka’s KafkaConsumer.seek method).
