Subject [jira] [Commented] (FLINK-1991) Return Table as DataSet<Tuple>
Date Fri, 08 May 2015 09:18:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-1991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14534183#comment-14534183

Aljoscha Krettek commented on FLINK-1991:
-----------------------------------------

But conversion to a tuple is only possible in a type-safe way if the user specifies the types
of the tuple. And this leads to bloat, since we need a lot of functions for this. Similar
to how we had the types() method on projections or other methods with tuples.

> WIth a {{TableEnvironment}} a {{Table}} can be converted into a Pojo or Row data set.
Both types have their issues. A Pojo needs to be explicitly defined and a Row cannot be easily
processed by a user-function.
> It would be good to have a method to convert a {{Table}} into a {{DataSet<Tuple>}}.
