Subject [GitHub] flink issue #2159: [FLINK-3942] [tableAPI] Add support for INTERSECT
Date Fri, 24 Jun 2016 23:07:30 GMT
Github user fhueske commented on the issue:

    Hi @wuchong, thanks for the PR. I think it is better to use a CoGroup instead of a Join
for `INTERSECT` (even though, I said "Join" in the original JIRA). For `INTERSECT ALL`, CoGroup
is required. It would also be good to update the Table API and SQL documentation as @mushketyk
    Thanks, Fabian
