Subj:   Re: How Do You Measure/Validate Compression Savings?
From:   Rob Steir

Dear Victor and everyone else who has replied to my original question, especially to John Hall and his strawman that greatly opened up the discussion.

One question that Victor raised that I wanted to address: If a compression tool was so good, why wouldn't Teradata just incorporate it into their system? The answer could be the same reason why Microsoft doesn't improve Outlook (can it be more slow in search/find queries?) and encourages vendors to provide improved performance applications to a variety of its software applications. For Teradata, perhaps the explanation is even simpler: A great compression tool has the potential to free up more perm space and CPUs and that ultimately delays purchase of node upgrades. Great for Teradata clients (and Teradata), in the long term, to have a more cost effective solution, but perhaps bad in the short-term (and most companies always operate in the short-term).

The original intent of this thread was to figure out the issues confronting DBAs and how to price our product in the marketplace.

Thank you very much for everyone's views as it's really great information, and I hope has spurred some thoughts, too.
