Kafka: Use Row SerDe + vectorization

    XMLWordPrintableJSON

Details

    Description

      KafkaHandler returns unvectorized rows which causes the operators downstream to be slower and sub-optimal.

      Hive has a vectorization shim which allows Kafka streams without complex projections to be wrapped into a vectorized reader via hive.vectorized.use.row.serde.deserialize.
