Question

SSIS "Slowly Changing Dimension" Performance issues

Asked by: banjara15

Hi SSIS Gurus,

I have a question related to the SSIS SCD transformation.
I need to load several Dimension tables with the number of records ranging from 1million to 10 million. I have read several articles about performance issues while using the SCD transformation. I would like to have your opinion on the following:

1) What are the alternatives for replacing the SCD transformation for performance improvement.
2) What performance tuning steps are suggested when using the SCD.
3) Can a Dimension table can be loaded with a StoredProcedure, how?
3) If you have some real life experiences with SCD performance, I'll really appreciate if you could share with me the things you did to resolve it.

This is urgent, I'll really appreciate your prompt reply
Thanks to you all for help..

Thanks for the links. I also found them earlier. Have you used the "Kimball SCD" transformation. Do you know any document that provides instructions on how to use it? I was trying to test and it seems to work fine when I was sending the outputs to the "RowCount", but when I changed the destination to OLE DB table it gave an error. If you have used it earlier, I'll appreciate if you could share the dtsx package where you used it or any supporting document..

I appreciate your help..

That looks like a very handy component. What error do you get when you redirect it to a different destination?
