> Hmm, right. But still, any output depends on the entire input, so it cannot be emitted on-the-fly while receiving partial input chunks. Right, these kinds of operators (ones that have to exhaust their inputs before emitting an output) are often called "blocking" in the literature (see e.g. http://pages.cs.wisc.edu/~jignesh/publ/Quickstep.pdf or http://www.vldb.org/pvldb/vol11/p2209-kersten.pdf). -- This is an automated message from the Apache Git Service.
