> Provide zipWithIndex utility in flink-contrib
> ---------------------------------------------
>
> Key: FLINK-2152
> URL: https://issues.apache.org/jira/browse/FLINK-2152
> Project: Flink
> Issue Type: Improvement
> Components: Java API
> Reporter: Robert Metzger
> Assignee: Andra Lungu
> Priority: Trivial
> Labels: starter
>
> We should provide a simple utility method for zipping elements in a data set
> with a dense index.
> its up for discussion whether we want it directly in the API or if we should
> provide it only as a utility from {{flink-contrib}}.
> I would put it in {{flink-contrib}}.
