    Description

      The ownership of these objects is a bit complicated because they can be either stack-allocated in the scanner thread or owned by a single-threaded scan node .

      It should be possible to simplify this once the multithreaded scan node is removed.

      See https://gerrit.cloudera.org/#/c/8025/11/be/src/exec/scanner-context.h@337 for some context.
