Default Minimizing Cube Build Time - 12-15-2004 , 10:43 AM






Can anyone point me to tips on minimizing cube build time and/or designing
cubes for quick build times? Without going into too much detail I have a
requirement to get cubes built as quickly as reasonably possible even if
there are running analysis penalities.

I'm building my cubes with DSO doing no pre-aggregation.
Example: At the moment a cube with 300 rows in the fact table and one
Distinct Count measure:
* 200 Member Dimension
* 200 Member 4 level dimension
* 100 Member 3 level time dimension
* 200 Member 4 level dimension

This example is presently taking me about 3 hours to build. Any ideas as
to where I should start researching? Much googling hasn't yielded me any good
information yet on how to attack the cube build time problem.

I finally ran across an article and discovered I was goggleing on the wrong
terms... "Reduce Cube Processing Time"... "Cube Build Time" gets you nada.

Look at the Analysis Services Performance Guide:
http://www.microsoft.com/technet/pro.../ansvcspg.mspx
It has an extremely extensive section on optimizing processing.
