Subject [jira] [Created] (ARROW-465) C++/Python: Investigate usage of madvise
Date Sun, 08 Jan 2017 15:41:58 GMT
Uwe L. Korn created ARROW-465:

             Summary: C++/Python: Investigate usage of madvise 
                 Key: ARROW-465
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Uwe L. Korn

In some usecases (e.g. Pandas->Arrow conversion) our main constraint is page faulting not
yet accessed pages. 

With {{madvise}} we can indicate our planned actions to the OS and may improve the performance
a bit in these cases.
