Where database blog posts get flame-broiled to perfection
Ah, yes, another SOSP paper promising to solve all our problems with a "simple fix." Fantastic. I can already hear the VP of Engineering clearing his throat in my doorway, clutching a printout of this, eyes gleaming with the dangerous light of someone who has just discovered a new, expensive way to do his job. Heāll tell me itās āfoundationalā and āparadigm-shifting.ā I'll just see the dollar signs spinning in his pupils.
Let's unpack this magical thinking, shall we? The system is called "Atropos," named after the Greek Fate who cuts the thread of life. How wonderfully dramatic. I also cut thingsābudgets, headcount, vendor contracts that have more mysterious surcharges than a TelCo bill. The difference is, my cutting saves money. This⦠this sounds like it costs a fortune to cut something for free.
They talk about "rogue whales" causing all the problems. Let me tell you, I know a thing or two about whales. They're the enterprise clients our sales team lands, and they're the vendors who see our P&L statement and decide we're their ticket to a new corporate campus. In this story, the vendor selling "Atropos" is the real Moby Dick, and our bank account is the Pequod.
So, the first "interesting point" is that our applications already contain "safe cancellation hooks." Oh, what a relief! For a moment I thought this would be invasive. Instead, it just relies on a decade's worth of undocumented, tribal-knowledge code written by engineers who have long since retired or fled to a competitor. The vendor will surely position this as a feature: "You've already done half the work!" What they mean is, "We're selling you a steering wheel, and now you just need to go find the rest of the car you apparently built years ago and forgot about."
Then we get to the core of the grift: the "lightweight" tracking. "Lightweight" is my number one vendor red flag. It's corporate-speak for "the performance impact is a feature, not a bug, and you'll solve it by buying more of our partner's hardware." It says they just need to "instrument" three operations by "wrapping code." I'll translate that from Engineering-ese into the language of an invoice:
So this "simple fix" is already a $1.3 million dollar problem in its first year, before it has saved us a single penny. This is what we in Finance call the Total Cost of Ownership, or as I prefer, the Total Cascade of Outrage.
And for what? The paper's evaluation is "strong." Of course it is. It was written by the people trying to get tenure, not the people trying to make payroll. They claim it restores throughput to "ninety six percent of normal." Wonderful. Let's do some back-of-the-napkin math on that ROI. If we have a catastrophic overload event once a quarter that costs us, say, $50,000 in lost revenue, this system might save us $200,000 a year. A $1.3 million investment to recoup $200k... that's a -85% ROI. The board will be thrilled. I'll get a promotion straight to the unemployment line.
My favorite part is this gem:
The cancellation rate is tiny: less than one in ten thousand requests!
They say this like it's a good thing! So weāre paying over a million dollars for a system that, by its own triumphant admission, does absolutely nothing 99.99% of the time. It's the world's most expensive smoke detector. It just sits there, consuming resources and licensing fees, waiting for a "rogue whale" to swim by. Meanwhile, we're locked in. Every critical piece of our database is now "wrapped" in their code. The cost to migrate away from it in three years will be even higher than the cost to install it. That's the real "nonlinear effect"āthe way vendor costs expand to fill any available budget, and then some.
So, no. I'm not impressed by the "clarity" of the design or the "clever idea" of estimating future demand. This isn't a solution. It's a mortgage. It's a beautifully designed, academically rigorous, peer-reviewed money pit. It solves a specific type of overload by creating a permanent, ongoing overload on my budget.
Now if you'll excuse me, I need to go pre-emptively deny a purchase order. Someone pass the Tylenol.
