[jira] [Created] (ARROW-3018) [Plasma] Improve random ObjectID generation


Philipp Moritz created ARROW-3018:
-------------------------------------

             Summary: [Plasma] Improve random ObjectID generation
                 Key: ARROW-3018
                 URL: https://issues.apache.org/jira/browse/ARROW-3018
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Plasma (C++)
    Affects Versions: 0.10.0
            Reporter: Philipp Moritz


As pointed out by [~pitrou], the mersenne twister in Plasma is currently not seeded appropriately (I just saw the comment recently): https://github.com/apache/arrow/pull/2039

I can submit a patch for Plasma but I'm also wondering if we should have a properly seeded random number in Arrow.
