Understood Scott. And I think your contribution will likely help me in my work in the future.

And I personally feel that all technical examples offered in venues such as this should have volume performance limitations investigated and noted in the article, as this issue can be one of the "deal breakers" for an ETL solution, and an unpleasant disappointment if users make incorrect assumptions.

And as I mentioned previously however, I also expect such performance limitations would NOT be an issue for many ETL problems, although as you have experienced, will be for some.

Best,

Ken
