I've met the Tin Man. Whilst looking for some MVCC/Locker debate I happened onto a Sybase Evangelist blog. Kind of like what I do, but he gets paid for it. Sigh. May be soon.
Anyway, this post is his paen to SSD, and this:
How big is your database?? **light bulb** Those same 10 SSD's get you a whopping 300-600GB of storage. You could just put the whole shooting match on SSD and forget the IO problems. Rep Server stable queue speed issues - vaporized.
Be warned, he makes the leap from Amazon sourced SSD to enterprise database storage (he doesn't mention STEC or Violin, for instance, but appears to be aware of earlier Texas Memory DRAM units); not really going to happen, so his arithmetic is off by a decimal point. But otherwise, he and I are on the same page, especially with skipping the "cache with SSD" silliness, and just storing to SSD. Schweeet. And he knows from schmere.
Now, hold Dorothy's hand.
IFF AI, as currently implemented, can intuit Special Relativity from just a clock tower and a moving tram will I take AI seriously.
Infinite granularity yields infinite complexity.

The world is not linear.

Well, I'm going to do it, whether the women like it or not. I'm going to protect them.

Scientists aren't vocal enough about science. There are large groups of people who think scientists are all frauds and who don't
believe in science, and they're being cultured by some of our far right-wing politicians, religious leaders and community leaders. -- Dr. McElhone/1974

To date, Microsoft is stating that organizations testing In-Memory OLTP have
seen transaction speeds improve by up to 30 times compared to past
performance, with the best performance gains achieved when the business
logic resides in the database and not in the applications.

I have had to explain and re-explain and re-explain and re-explain, you know, how relational databases work, what is an eigenvector,
what is dimensionality reduction.
-- Christopher Wylie/2018
... but Flash-based storage has such a different performance profile from rotating media, that I suspect that it will end up having
a large impact on filesystem design. Right now, most filesystems tend to be designed with the latencies of rotating media in mind.

This Week's thought
Counties with the biggest Democratic victories in 2020 delivered 1.9 million fewer votes for Ms. Harris than they had for Mr. Biden. The nation's most Republican-heavy counties turned out an additional 1.2 million votes for Mr. Trump this year -- Michael C. Bender/2024 [pussies; but what I suspected]
See you next week in a brand new show©Heckle and Jeckle
In a time of SSD, multi-core/processor, two terabyte memory and Optane App Direct Mode machines, there is no reason not to
build from BCNF data. Time to do what Dr. Codd demonstrated. Technology has finally caught up with the maths.

Shameless Plug
I know a little something about SQL, DB2 (preferably LUW, z/OS if the money's right), Oracle, SQL Server, Postgres, and database design in general. Mentoring/teaching/consulting on a short term basis, too. And a bit of stat analysis if it's R.
