Subject [jira] [Commented] (FLINK-2971) Add outer joins to the Table API
Date Wed, 27 Apr 2016 15:02:12 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2971?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15260294#comment-15260294

Dawid Wysakowicz commented on FLINK-2971:
-----------------------------------------

I started with that idea, just one small disadvantage I saw was it will result in 4(3* outer
+ inner)*3(no joinPredicate, as Expression, as String) = 12 methods. But it would probably
be more user friendly. So if you're ok with it, I will change it.

> Since Flink now supports outer joins, the Table API can also support left, right and
full outer joins.
> Given that null values are properly supported by RowSerializer etc.
