Subject [GitHub] spark pull request: [SPARK-2679] [MLLib] Ser/De for Double
Date Fri, 25 Jul 2014 00:51:00 GMT
Github user mengxr commented on the pull request:
    If we need a complex type in the future, we can add a separate SerDe for it. Since double
only has 8 byte, adding the magic byte increases the storage by 12.5%.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at or file a JIRA ticket
