How to process the cube faster

Hi,

I have a Cube that takes around hour to process, and yes it will because, I have more than 2000 Millions records to be processed.

Is there any way where I can process only the new records which are added today to the fact table, instead of processing complete cube. I thought of adding partitions in the cube, but this will be a manual work for me as everytime I have to add the new partitions, which I dont want to.

Is there any other way to process newly added data?

Any suggestions please ?

Thanks
