Create ordered CCI withOPTION (MAXDOP = 1). Each thread used for ordered CCI creation works on a subset of data and sorts it locally. There's no global sorting across data sorted by different threads. Using parallel threads can reduce the time to create an ordered CCI but generate more ov...

Looking at that, I wondered what would happen if I made a simple change to the code to force MAXDOP (maximum degree of parallelism) to 1. So, let's see what happened, here is the new code that was run. USE[RunningTotals] GO exec dbo.ResetRTTestP; go DBCCFREEPROCCACHE WITH NO_INFOMS...
option(maxdop2) Something went really wrong as it took 1:13 minutes to complete the execution on my system, so what was wrong in the above execution. Maybe we are running with Maxdop 2. Let use maximum capacity of system CPU processing and check how much query performance improved. ...
OPTION(MAXDOP1,RECOMPILE); The key differentiator from many of the queries out there is that the expression againststmt.nodesis performing two different filters - it is making sure that we only return the index with the given name and that has a parent index operation that was forced. Here...
