Subject [GitHub] flink pull request: [FLINK-3282] Add FlinkRelNode interface.
Date Thu, 28 Jan 2016 12:14:48 GMT
Github user twalthr commented on the pull request:

    When I wrote my SQL prototype I also thought about using Java because Calcite is written
in Java, but since it is easy to use Java classes from Scala and Scala has a much better feature
set and is more concise, I would strongly insist to use Scala. When we implement the code
generation in the DataSet RelNodes, Scala will make our life much easier. Mixing up languages
in one flink module is not very comfortable anyway.

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 infrastructure@apache.org or file a JIRA ticket
with INFRA.
