Where database blog posts get flame-broiled to perfection
Alright team, gather 'round. Marketing just forwarded me the latest "thought leadership" piece from one of our... potential database partners. Theyâve spent over a thousand words celebrating a âfeatureâ that amounts to rewarding bad programming. Let's dissect this masterpiece of corporate fan-fiction before they try to send us an invoice for the privilege of reading it.
First, theyâve managed to brand ânot doing work when nothing changesâ as a revolutionary optimization. The central premise here is that our applications are so inefficientâmindlessly updating fields with the exact same dataâthat we need a database smart enough to clean up the mess. This isn't a feature; it's an expensive crutch for sloppy code. Theyâre selling us a helmet by arguing we should be running into walls more often. Instead of fixing the leaky faucet in the application layer, they want to sell us a billion-dollar, diamond-encrusted bucket to put underneath it.
Second, letâs talk Total Cost of Ownership. The author needed a Docker container, a log parser, and a deep understanding of write component verbosity just to prove this "benefit." What does that tell me? It tells me that when this system inevitably breaks, we're not calling our in-house team. We're calling a consultant who bills at $400/hour to decipher JSON logs. Letâs do some quick math: One senior engineer's salary to build around these "quirks" ($180k) + one specialized consultant on retainer for when it goes sideways ($100k) + "enterprise-grade" licensing that charges per read, even the useless ones ($250k). Suddenly, this "free optimization" is costing us half a million dollars a year just to avoid writing a proper if statement in the application code.
Third, the comparison to PostgreSQL is a masterclass in spin. They present SQL's behaviorâacquiring locks, firing triggers, and creating an audit trailâas a flaw.
In PostgreSQL, an UPDATE statement indicates an intention to perform an operation, and the database executes it even if the stored value remains unchanged. Yes, exactly! Thatâs called a transaction log. That's called compliance. Thatâs called knowing what the hell happened. Theyâre framing predictable, auditable behavior as a burdensome "intention" while positioning their black box as a more enlightened "state." Oh, I see. It's not a bug, it's a philosophical divergence on the nature of persistence. Tell that to the auditors when we can't prove a user attempted to change a record.
Finally, this entire article is the vendor lock-in two-step. They highlight a niche, esoteric behavior that differs from the industry standard. Then, they encourage you to build your entire application architecture around it, praising "idempotent, retry-friendly patterns" that rely on this specific implementation. A few years down the line, when their pricing model "evolves" to charge us based on CPU cycles spent comparing documents to see if they're identical, we're trapped. Migrating off would require a complete logic rewrite. They sell you a unique key, then change the lock every year.
Honestly, sometimes I feel like we're not buying databases anymore; we're funding PhD theses on problems no one actually has. Itâs a solution in search of a six-figure support contract. Now, if you'll excuse me, I need to go approve a PO for a new coffee machine. At least I know what that does.
