title: Kafka Connect and Hive -> Merge
body: <p>Given the Hive's features of ACID incremental rollup Merge, I'm trying to understand if:</p>
  <ul>
  <li>Hive Lenses sink: <a href="https://docs.lenses.io/5.0/integrations/connectors/stream-reactor/sinks/hivesinkconnector/" rel="nofollow noreferrer">https://docs.lenses.io/5.0/integrations/connectors/stream-reactor/sinks/hivesinkconnector/</a></li>
  <li>Confluent Hadoop Sink: <a href="https://docs.confluent.io/kafka-connect-hdfs/current/overview.html" rel="nofollow noreferrer">https://docs.confluent.io/kafka-connect-hdfs/current/overview.html</a></li>
  </ul>
  <p>can apply the incremental rollups as well. I wasn't able to find documentation about their nature of being pure APPEND-ONLY or having also rollups.</p>
  <p>The rollup update seems a pretty common problem that I would expect opensource tools of the Kafka Connect family to have addressed.</p>
