A Peek Inside: Getting the most from data refresh
Recently there was a forum post concerning how PowerPivot parallelizes data refresh . . and I thought this might be an interesting topic for a “Peek Inside” blog posting. The first question is: Why are we doing this? What is the purpose of parallelizing data refresh? Why is this so important? Well . . there are two reasons. The first reason is that we want to get the maximum throughput from all of the compute resources that we have in the farm. We paid a lot for the servers and we want to keep them busy. However, secondly, particularly as users start deploying more and more workbooks, the number of jobs will increase as well. We expect that the automatic refresh capabilities of the PowerPivot system will be a popular feature. Information workers like to keep their workbooks up-to-date – and data refresh is a powerful new feature of PowerPivot.
