Hi, awesome series, it helps me a lot to understand bit after bit.
I have one question though, you wrote "Because the Leader Node won't return it's results until all Compute Nodes have finished,in the above scenario nodes one, two and four would finish way faster than Three and Three would act as a bottleneck." In which case? If I understood correctly, the leader node should cut off these overloaded nodes in case when I'd have query with filter for, say, only Customer Two.
Would it be a bottleneck when I had an aggregation for all customers then?
For further actions, you may consider blocking this person and/or reporting abuse
