-------------------------------------------------------------

[~bslim] {{kafka_storage_handler}} has been failing consistently in last few runs, most likely caused by the commit for this jira. Can you please take a look?

> 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}}.
