Luca,

Thanks for the reply, yes that will return the correct results. However the
orientdb way seem to be to use quite a few sub queries (correct me if I'm
wrong), so just having the top level EXPLAINed means that its really hard
to profile queries until it hits an environment with a large amount of data.

This was why I originally raised it in github issues because I assumed it
was a bug. From what you say I'm guessing its a not, but is there any work
arounds to get those sort of metrics?

Thanks,
Jamie
Hi Jamie,
What about the result of:

EXPLAIN select from Vertex

I think the profiler doesn't collect metrics from sub-queries.
