    Description

      See the discussion https://github.com/apache/kafka/pull/6654#discussion_r280231439

      The session merging logic generates a tombstone in addition to an update when the session window already exists. It's not a correctness issue, just a small performance hit, because that tombstone is immediately invalidated by the update.
