Hey Jin, are you interested in implementing this functionality? I created a JIRA that describes a safe semantics for it here: https://issues.apache.org/jira/browse/ARROW-1927 I think it would be valuable to have, even though it is not strictly necessary as Robert points out. Deleting objects that are not needed any more can prevent important objects from getting evicted. -- Philipp. On Thu, Dec 14, 2017 at 2:43 PM, Robert Nishihara <robertnishih...@gmail.com > wrote: > Currently, you don't need to evict the object.
