> Add messageHandler to Kafka 10 direct stream API
> ------------------------------------------------
>
> Key: SPARK-28415
> URL: https://issues.apache.org/jira/browse/SPARK-28415
> Project: Spark
> Issue Type: New Feature
> Components: DStreams
> Affects Versions: 3.0.0
> Reporter: Michael Spector
> Priority: Major
>
> Lack of messageHandler parameter to KafkaUtils.createDirectStrem(...) in new
> Kafka API is what prevents us from upgrading our processes to use it, and
> here's why:
> # messageHandler() allowed parsing / filtering / projecting huge JSON files
> at an early stage (only a small subset of JSON fields is required for a
> process), without this current cluster configuration doesn't keep up with the
> traffic.
> # Transforming Kafka events right after a stream is created prevents from
> using HasOffsetRanges interface later. This means that whole message must be
> propagated to the end of a pipeline, which is very ineffective.
