Hi, Thanks! Can we have the customer number as the RowKey for the customer (client) master table? Please help in educating me on the advantage and disadvantage of having customer number as the Row key...
Also SCD2 we may need to implement in that table.. will it work if I have like that? Or SCD2 is not needed instead we can achieve the same by increasing the version number that it will hold? pls suggest... regards, Rams On Mon, Nov 26, 2012 at 1:10 PM, Li, Min <m...@microstrategy.com> wrote: > When 1 cf need to do split, other 599 cfs will split at the same time.
