-----------------------------------------

We are having the discussion right now about reorganizing the Streaming API a
bit. I think the aggregations (grouped and non-grouped) without windows should
be removed to make the API clearer and safer.
> Add count method to GroupedDataStream

> Components: Streaming
> Reporter: Gábor Hermann
> Assignee: Gábor Hermann
> Priority: Minor

> As aggregations from DataStream was removed, the {{count}} method was also
> removed. A count method should be introduced to the {{GroupedDataStream<T>}}
> that returns a {{Tuple2<T, Long>}} of the latest element and number of the
> elements in the stream with the same key.
