Subject [GitHub] flink issue #2870: [FLINK-4565] Support for SQL IN operator

Github user NickolayVasilishin commented on the issue:

    Hi, @fhueske.
    I will update PR with fixed version soon. 
    But I have a question. Is deduplication at In#toRexNode really needed since we are going
to use hashset anyway? It's easy to implement, we just can take distinct values here.
    And I think I will open PR with subquery implementation today. It's rather straightforward,
but works.

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.
