Initial Comment:
Would it be possible to output early results instead of waiting for the

Message:
Results are returned as soon as they are available.
Closing as the bulk processing paradigm isn't going to be changed.

Message:
Is this feasible at all to keep as request? I think we will never do this
as it is contrary to our model.

I just reported a bug on that, the server output is broken.

To be a bit more verbose: MonetDB uses (for good reasons; see our research
literature) "bulk processing" (as opposed to pipelining in several other
DBMSs); hence, there are now "early results" that the client could output;
no single result has been produced before the last operator in the
respective MIL/MAL (binary algebra) plan is starting to execute; the time
span from "producing" the first to the last result item is only the time
the very last operator in the generated MIL/MAL (binary algebra) plan takes
to execute --- usually only a faction of the total query execution time
...

You're probably after a server change, not a client change.
