> With the recent changes/additions to {{DataStreamUtils.collect()}} that make it more robust by using the regular REST client to fetch results from operators it might make sense to add a {{collect()}} operation right on {{DataStream}}.
> This operation is still not meant for big data volumes but I think it can be useful for debugging and fetching small amounts of messages to the client. When we do this, we can also think about changing {{print()}} to print on the client instead of to the {{TaskManager}} stdout. I think the current behaviour of this operation is mostly confusing for users.
