Question: Does the Bizgress/MPP use threading for this concurrency?
Or forking?
If it does so via forking, that's more portable, and less dependent on
specific complexities of threading implementations (which amounts to
non-portability ;-)).
Most times Jan comes to town, we spend a few minutes musing about the
"splitting queries across threads" problem, and dismiss it again; if
there's the beginning of a "split across processes," that's decidedly
neat :-).
