Now as partitioning is mainly there to allow you to assign more than one CPU to the aggregation process, and to allow you to selectively aggregate just the partitions that receive new data, I can’t really see the point of partitioning on this level - I’d have gone for month, or more likely, quarter, a good balance between improving load times and not having too much data in the topmost partition that I can’t then pre-summarise. I wonder if this feature has been completed yet?

I’ve just tried them all myself, they’re all working for me. Can you point out which ones are causing problems, what is the URL that they’re referencing? Andrew, which link(s) is/are broken?

Looks like the forum software appended some kind of cookie code to the URLS, which don’t work if someone else uses them. I’ve revised the links now, hopefully they should work. Hi Don,
