Stephen Swoyer (tdwi) is summarizing Richard Winter’s research into the topic of cost-based efficiency of Hadoop vs data warehouses:
“Under what circumstances, in fact, does Hadoop save you a lot of money, and
under what circumstances does a data warehouse save you a lot of money?”
The conversation happened at a Teradata event, so you might already guess some of the findings. Anyways without seeing the data it’s difficult to agree or disagree:
In fact, he argued that misusing Hadoop for some types of
decision support workloads could cost up to 2.8x more than
a data warehouse.
