Hi All I have a very large data set for a DW and I created a materialized view on it to give me a quick access to group by and summarization results, I want some way to be able to update the MV with just the delta after I perform an incremental load to the base fact or dimension tables on which the MV is built. From what I have played with so far, I don't see a ready solution. Fast refreshes don't work when MV is on complex view. We are talking about dimension tables with possibly close to a billion rows, and fact tables of similar proportions, so the time taken to refresh the MV becomes a factor.
Any useful suggestions, write-up's, white papers in this regard would be extremely helpful and welcome. Ta muchly in advance !
