Where database blog posts get flame-broiled to perfection
Ah, yes. Another masterpiece. It's always so refreshing to read a thoughtful piece that begins with the classic "two hard problems" joke. It lets me know we're in the hands of a true practitioner, someone who has clearly never had to deal with the actual three hard problems of production systems: DNS propagation, expired TLS certificates, and a junior engineer being given root access on a Friday afternoon.
I'm particularly inspired by the breezy confidence with which "caching" is presented as a fundamental strategy. It's so elegant in theory. Just a simple key-value store that makes everything magically faster. It gives me the same warm, fuzzy feeling I get when a project manager shows me a flowchart where one of the boxes just says "AI/ML."
I can already see the change request now. It'll be a one-line ticket: "Implement new distributed caching layer for performance." And it will come with a whole host of beautiful promises.
My favorite, of course, will be the "zero-downtime" migration. It's my favorite phrase in the English language, a beautiful little lie we tell ourselves before the ritual sacrifice of a holiday weekend. I can already picture the game plan: a "simple" feature flag, a "painless" data backfill script, and a "seamless" cutover.
And I can also picture myself, at 3:15 AM on the Sunday of Memorial Day weekend, watching that "seamless" cutover trigger a thundering herd of cache misses that saturates every database connection and grinds the entire platform to a halt. The best part will be when we find out the new caching client has a subtle memory leak, but we won't know that for sure because the monitoring for it is still a story in the backlog, optimistically titled:
TODO: Add Prometheus exporters for NewShinyCacheThingy.
Oh, the monitoring! That’s the most forward-thinking part of these grand designs. The dashboards will be beautiful—full of green squares and vanity metrics like "Cache Hit Ratio," which will be a solid 99.8%. Of course, the 0.2% of misses will all be for the primary authentication service, but hey, that's a detail. The important thing is that the big number on the big screen looks good for the VPs. We'll get an alert when the system is well and truly dead, probably from a customer complaining on Twitter, which remains the most reliable end-to-end monitoring tool ever invented.
This whole proposal, with its clean lines and confident assertions, reminds me of my laptop lid. It’s a graveyard of vendor stickers from databases and platforms that were also going to solve one simple problem. There’s my shiny foil sticker for RethinkDB, right next to the holographic one from CoreOS, and let's not forget good old GobblinDB, which promised "petabyte-scale ingestion with ACID guarantees." They all looked fantastic in the blog posts, too.
So please, keep writing these. They're great. They give the developers a sense of purpose and the architects a new set of buzzwords for their slide decks.
You worry about cache invalidation. I'll be here, writing the post-mortem.
Alright, settle down, whippersnappers. I just spilled my coffee—the kind that could strip paint, the only real kind—all over my desk reading this latest masterpiece of marketing fluff from the MongoDB crew. They're talking about a "SaaS Security Capability Framework." Oh, a new acronym! My heart flutters. It's like watching someone rediscover fire and try to sell you a subscription to it. Let's pour a fresh cup of joe and go through this "revolution" one piece at a time.
First, they proudly announce they've identified a "gap in cloud security." A gap! You kids think you found a gap? Back in my day, the "gap" was the physical space between the mainframe and the tape library, and you'd better pray the operator didn't trip while carrying the nightly backup reel. This whole song and dance about needing a standard to see what security controls an application has... we called that a "technical manual." It came in a three-ring binder that weighed more than your laptop, and you read it. All of it. You didn't need a "framework" to tell you that giving EVERYONE SYSADM privileges was a bad idea.
Then we get to the meat of it. The framework helps with "Identity and Access Management (IAM)." They boast about providing “robust, modern controls for user access, including SSO enforcement, non-human identity (NHI) governance, and a dedicated read-only security auditor role.” Modern controls? Son, in 1985, we were using RACF on the mainframe to manage access control lists that would make your head spin. A "non-human identity"? We called that a service account for the nightly COBOL batch job. It had exactly the permissions it needed to run, and its credentials were baked into a JCL script that was physically locked in a cabinet. This isn't new; you just gave it a three-letter acronym and made it sound like you're managing Cylons.
Oh, and this one's a gem. The framework ensures you can "programmatically query... all security configurations." My goodness, hold the phone. You mean to tell me you've invented the ability to run a query against a system catalog? Groundbreaking. I was writing SELECT statements against DB2 system tables to check user privileges while you were still trying to figure out how to load a floppy disk. The idea that this is some novel feature you need a "working group" to dream up is just precious. Welcome to 1983, kids. The water's fine.
The section on "Logging and Monitoring (LOG)" is my personal favorite. It calls for "comprehensive requirements for machine-readable logs with mandatory fields." I've seen tape reels of audit logs that, if stretched end-to-end, could tie a bow around the moon. We logged every single transaction, every failed login, every query that even sniffed the payroll table. We didn't need a framework to tell us to do it; it was called "covering your backside." Your "machine-readable JSON" is just a verbose, bracket-happy version of the fixed-width text files we were parsing with homegrown PERL scripts before you were born.
Finally, the kicker: "Our involvement in creating the SSCF stems from our deep commitment... The principles outlined in the SSCF... are philosophies we already built into our own data platform." Well, isn't that convenient? You helped invent a standard that—what a coincidence!—you already meet. That’s like "co-chairing" a committee to declare that the best vehicle has four wheels and a motor, right after you've started selling cars. We used to call that "writing the RFP to match the product you already bought." At least we were honest about it.
Anyway, it's been a real treat reading your little manifesto. Now if you'll excuse me, I have to go check on a database that's been running without a "chaotic landscape" or a "security blind spot" since before the word "SaaS" was even a typo.
Thanks for the chuckle. I'll be sure to never read your blog again.
Alright, let's pull up a chair and review this... masterpiece of performance analysis. I've seen more robust security planning in a public S3 bucket. While you're busy counting query-per-second deltas that are statistically indistinguishable from a stiff breeze, let's talk about the gaping holes you've benchmarked into existence.
First off, you "compiled Postgres from source." Of course you did. Because who needs stable, vendor-supported packages with security patches and a verifiable supply chain? You've created an artisanal, unauditable binary on a fresh-out-of-the-oven Ubuntu release. I have no idea what compiler flags you used, if you enabled basic exploit mitigations like PIE or FORTIFY_SOURCE, or if you accidentally pulled in a backdoored dependency from some sketchy repo. This isn't a build; it's Patient Zero for a novel malware strain. Your make command is the beginning of our next incident report.
You're running this on a "SuperMicro SuperWorkstation." Cute. A glorified desktop. Let me guess, the IPMI is wide open with the default ADMIN/ADMIN credentials, the BIOS hasn't been updated since it left the factory, and you've disabled all CPU vulnerability mitigations in the kernel for that extra 1% QPS. This entire setup is a sterile lab environment that has zero resemblance to a production system. You haven't benchmarked Postgres; you've benchmarked how fast a database can run when you ignore every single security control required to pass even a cursory audit. Good luck explaining this to the SOC 2 auditor when they ask about your physical and environmental controls.
Let's talk about your configuration. You're testing with io_method=io_uring. Ah yes, the kernel's favorite attack surface. You're chasing microscopic performance gains by using an I/O interface that has been a veritable parade of high-severity local privilege escalation CVEs. While you're celebrating a 1% throughput improvement on random-points, an attacker is celebrating a 100% success rate at getting root on your host. This isn't a feature; it's a bug bounty speedrun waiting to happen. You're essentially benchmarking how quickly you can get owned.
This whole exercise is based on sysbench running with 16 clients in a tight loop. Your benchmark simulates a world with no network latency, no TLS overhead, no authentication handshakes, no complex application logic, no row-level security, and certainly no audit logging. You're measuring a fantasy. In the real world, where we have to do inconvenient things like encrypt traffic and log user activity, your precious 3% regression will be lost in the noise. Your benchmark is the equivalent of testing a car's top speed by dropping it out of a plane—the numbers are impressive, but utterly irrelevant to its actual function.
And the grand takeaway? A 1-3% performance difference that you admit "will take more time to gain confidence in." You've introduced a mountain of operational risk, created a bespoke binary of questionable origin, and stress-tested a known kernel vulnerability vector... all to prove next to nothing. The amount of attack surface you've embraced for a performance gain that a user would never notice is, frankly, astounding. It's the most elaborate and pointless self-sabotage I've seen all quarter.
This isn't a performance report; it's a pre-mortem. I give it six months before the forensics team is picking through the smoldering ruins of this "SuperWorkstation" trying to figure out how every single row of data ended up on the dark web. But hey, at least you'll have some really detailed charts for the breach notification letter.
Ah, another dispatch from the front lines of digital disruption. How positively thrilling. I must commend the author's prolific prose on the subject of File Copy-Based Initial Sync. The benchmarks are beautiful, the graphs are certainly… graphic. It's a masterful presentation on how we can make a very specific, technical process infinitesimally faster. My compliments to the chef.
Of course, reading this, my mind doesn’t drift to the milliseconds saved during a data sync; it drifts to the dollars flying out of my budget. I love these "significant improvements," especially when they're nestled inside a conveniently custom, "open-source" solution. It’s a classic play. The first taste is free, but the full meal costs a fortune. This fantastical feature, FCBIS, is a perfect example. It's not a feature; it's the cheese in the mousetrap.
You see, the article presents this as a simple, elegant upgrade. But I’ve been balancing budgets since before your engineers were debugging "Hello, World!" and I know a pricey panacea when I see one. Let's perform a little back-of-the-napkin calculation on the Total Cost of Ownership, shall we? Let me just get my abacus.
The article implies the cost is zero. Adorable. The true cost begins the moment we decide to adopt this "improvement."
So, this "free" feature that offers "significant improvements" has a Year-One TCO of $700,000. And that’s before the recurring support contract, which I’m sure is priced with all the restraint of a sailor on shore leave.
And for what ROI? The article boasts of faster initial syncs.
Those first results already suggested significant improvements compared to the default Logical Initial Sync.
Fantastic. Our initial sync, a process that happens during a catastrophic failure or a major topology change, might now be four hours faster. Let's assume this saves us one engineer's time for half a day, once a year. That’s a tangible savings of… about $400.
So, we’re being asked to spend $700,000 to save $400 a year. The ROI on that is so deeply negative it’s approaching the temperature of deep space. At this burn rate, we'll achieve bankruptcy with large-scale scalability.
This isn't a technical whitepaper. It’s an invoice written in prose. It's a beautifully crafted argument for vendor lock-in, a masterclass in monetizing open-source, and a stunning monument to treating corporate budgets like an all-you-can-eat buffet.
This isn’t a feature; it's an annuity plan for your consulting division. Now if you’ll excuse me, I need to go approve a request for more paper clips. At least I understand their value proposition.
Ah, another wonderfully thorough technical deep-dive. I always appreciate when vendors take the time to explain, in excruciating detail, all the innovative ways they've found to spend my money. It’s so transparent of them. The sheer volume of command-line gymnastics and hexadecimal dumps here is a testament to their commitment to simplicity and ease of use. I can already see the line item on the invoice: “‘wt’ utility whisperer,” $450/hour, 200-hour minimum.
I must commend the elegance of the Multi-Version Concurrency Control implementation. It’s truly a marvel of modern engineering. They’ve managed to provide “lock-free read consistency” by simply keeping uncommitted changes in memory. Brilliant! Why bother with the messy business of writing to disk when you can just require your customers to buy enough RAM to park a 747? It’s a bold strategy, betting the success of our critical transactions on our willingness to perpetually expand our hardware budget. I'm sure the folks in procurement will be thrilled.
But the real stroke of genius, the part that truly brings a tear to a CFO’s eye, is the “durable history store.” Let me see if I have this right.
Each entry contains MVCC metadata and the full previous BSON document, representing a full before-image of the collection's document, even if only a single field changed.
My goodness, that's just… so generous. They’re not just storing the change, they’re storing the entire record all over again. For free, I'm sure. Let’s do some quick math on the back of this cocktail napkin, shall we?
WiredTigerHS.wt file.If we have one million updates a day on documents of this size, that’s… let me see… an extra 10 gigabytes of storage per day just for the "before-images." At scale, my storage bill will have more zeros than their last funding round. The ROI on this is just staggering, truly. We'll achieve peak bankruptcy in record time.
And I love the subtle digs at the competition. They've solved the "table bloat found in PostgreSQL" by creating a system where the history file bloats instead. It’s not a bug, it’s a feature! Why bother with a free, well-understood process like VACUUM when you can just buy more and more high-performance storage? It’s the gift that keeps on giving—to the hardware vendor.
Then there's this little gem, tucked away at the end:
However, the trade-off is that long-running transactions may abort if they cannot fit into memory.
Oh, a trade-off! How quaint. So my end-of-quarter financial consolidation report, which is by definition a long-running transaction, might just… give up? Because it ran out of room in the in-memory playpen the database vendor designed? That’s not a trade-off; that’s a business continuity risk they're asking me to subsidize with CAPEX.
Let’s calculate the "true cost" of this marvel, shall we?
So the total cost of ownership isn't $X, it's more like $X + $500k + (Storage Bill * 2) + a blank check for the hardware team. The five-year TCO looks less like a projection and more like a ransom note.
Honestly, sometimes I feel like the entire database industry is just a competition to see who can come up with the most convoluted way to store a byte of data. They talk about MVCC and B-trees, and all I hear is the gentle, rhythmic sound of a cash register. Sigh. Back to the spreadsheets. Someone has to figure out how to pay for all this innovation.
Alright, settle down, kids. Let me put down my coffee—the kind that's brewed strong enough to dissolve a spoon—and take a look at this... masterpiece of technical discovery. So, MongoDB has figured out how to keep old versions of data around using something they call a "durable history store."
How precious. It's like watching my grandson show me a vinyl record he found, thinking he's unearthed some lost magic.
Back in my day, we called this concept "logging" and "rollback segments," and we were doing it on DB2 on a System/370 mainframe while most of these developers' parents were still learning how to use a fork. But sure, slap a fancy name on it, call it MVCC, and act like you've just invented fire. It's adorable, really.
Let's break down this... 'architecture.'
They're very proud of their No-Force/No-Steal policy. "Uncommitted changes stay only in memory." Let me translate that from Silicon Valley jargon into English for you: "We pray the power doesn't go out." In memory. You mean in that volatile stuff that vanishes faster than a startup's funding when the power flickers? I've seen entire data centers go dark because a janitor tripped over the wrong plug. We had uninterruptible power supplies the size of a Buick and we still wrote every damned thing to disk, because that's where data lives. We didn't just cross our fingers and hope the write-ahead log could piece it all back together from memory dust.
And then I see this. This beautiful, unholy pipeline of commands: wt ... dump ... | grep ... | cut ... | xxd -r -p | bsondump.
My God, it’s like watching a chimp trying to open a can with a rock. You had to chain together four different utilities just to read your own data file? Back in '88, I had an ISPF panel on a 3270 terminal that could dump a VSAM file, format it in EBCDIC or HEX, and print it to a line printer down the hall before your artisanal coffee was even cool enough to sip. This command line salad you've got here isn't "clever," it's a cry for help. It tells me you built a database engine but forgot to build a damn steering wheel for it.
And what does this grand exploration reveal?
Each entry contains MVCC metadata and the full previous BSON document, representing a full before-image of the collection's document, even if only a single field changed.
A full before-image. So, let me get this straight. You change one character in a 1MB "document," and to keep track of it, you write another full 1MB document to your little "history store"? Congratulations, you've invented the most inefficient transaction logging in the history of computing. We were using change vectors and delta encodings in COBOL programs writing to tape drives when a megabyte was the size of a refrigerator and cost more than a house. We had to care about space. You kids have so much cheap disk you just throw copies of everything around like confetti and call it "web scale."
The author then has the gall to compare this to Oracle and PostgreSQL.
And this is the part that made me spit out my coffee:
...the trade-off is that long-running transactions may abort if they cannot fit into memory.
There it is. The punchline. Your "modern, horizontally scalable" database just... gives up. It throws its hands in the air and says, "Sorry, this is too much work for me." I used to run batch jobs that updated millions of records and ran for 18 hours straight, processing stacks of punch cards fed into a reader. The job didn't "abort because it couldn't fit in memory." The job ran until it was done, or until the machine caught fire. Usually the former.
So let me predict the future for you. Give 'em five years. They'll be writing breathless blog posts about their next revolutionary feature: a "persistent transactional memory buffer" that's written to disk before commit. They'll call it the "Pre-Commit Durability Layer" or some other nonsense. We called it a "redo log." Then they'll figure out that storing full BSON objects is wasteful, and they'll invent "delta-based historical snapshots."
They're not innovating. They're just speed-running the last 40 years of solved database problems and calling each mistake a feature. Now if you'll excuse me, I have to go check on my tape rotations. At least I know where that data will be tomorrow.
Well, look at this. One of the fresh-faced junior admins, bless his heart, slid this article onto my desk—printed out, of course, because he knows I don't trust those flickering web browsers. Said it was "critical reading." I'll give it this: it's a real page-turner, if you're a fan of watching people solve problems we ironed out before the Berlin Wall came down.
It's just delightful to see you youngsters discovering the concept of a finite number space. OID exhaustion. Sounds so dramatic, doesn't it? Like you've run out of internet. Oh no, the 32-bit integer counter wrapped around! The humanity! Back in my day, we didn't have the luxury of billions of anything. We had to plan our file systems with a pencil, paper, and a healthy fear of the system operator. You kids treat storage like an all-you-can-eat buffet and then write think-pieces when you finally get a tummy ache. We had to manually allocate cylinders on a DASD pack. You wouldn't last five minutes.
And this... this TOAST table business. I had to read that twice. You're telling me your fancy, modern database takes oversized data and... makes toast out of it? What's next, a "BAGEL" protocol for indexing? A "CROISSANT" framework for replication? We called this "data overflow handling" and it was managed with pointer records in an IMS database. It wasn't cute, it wasn't named after breakfast, and it worked. You've just invented a more complicated version of a linked list and given it a name that makes me hungry.
The troubleshooting advice is a real hoot, too. You have to "review wait events" and "monitor session activity" to figure out the system is grinding to a halt. It’s like watching a toddler discover his own toes and calling it a breakthrough in anatomical science.
...we discuss practical solutions, from cleaning up data to more advanced strategies such as partitioning.
"Advanced strategies such as partitioning." I think I just sprained something laughing. Advanced? Son, we were partitioning datasets on DB2 back in 1985 on systems with less processing power than your smart watch. We did it with 80-column punch cards and JCL that would make a grown man weep. It wasn't an "advanced strategy," it was Tuesday. You have a keyword that does it for you. We had to offer a blood sacrifice to the mainframe and hope we didn't get a S0C7 abend.
The real solution was always proper data hygiene, but nobody wants to hear that. It’s more fun to build a digital Rube Goldberg machine of microservices and then write a blog post about the one loose screw you found. I remember spending a whole weekend one time just spooling data off to tape reels—reels the size of dinner plates—just to defragment a database. We'd load them up in a tape library that sounded like a locomotive crashing, and we were grateful for it. You all talk about data cleanup like it’s a chore. For us, it was the whole job.
So, thanks for this enlightening read. It’s been a fascinating glimpse into how all the problems we solved thirty years ago in COBOL are now being rediscovered with more buzzwords and, apparently, worse planning. It's like putting racing stripes on a lawnmower and calling it a sports car.
Truly, a fantastic piece of work. Now if you'll excuse me, I have some VSAM files to check. Rest assured, I will never, ever be reading your blog again. It’s been a pleasure.
Alright, let's pull up a chair. I've got my coffee, my risk assessment matrix, and a fresh pot of existential dread. Let's read this... benchmark report.
"Postgres continues to do a great job at avoiding regressions over time." Oh, that's just wonderful. A round of applause for the Postgres team. You've managed to not make the car actively slower while bolting on new features. I feel so much safer already. It’s like celebrating that your new skyscraper design includes floors. The bar is, as always, on the ground.
But let's dig in, shall we? Because the real gems, the future CVEs, are always in the details you gloss over.
First, your lab environment. An ASUS ExpertCenter PN53. Are you kidding me? That's not a server; that's the box my CFO uses for his Zoom calls. You're running "benchmarks" on a consumer-grade desktop toy with SMT disabled, probably because you read a blog post about Spectre from 2018 and thought, "I'm something of a security engineer myself." What other mitigations did you forget? Is the lid physically open for "air-gapped cooling"? This isn't a hardware spec; it's a cry for help.
And you compiled from source. Fantastic. I hope you enjoyed your make command. Did you verify the GPG signature of the tarball? Did you run a checksum against a trusted source? Did you personally audit the entire toolchain and all dependencies for supply chain vulnerabilities? Of course you didn't. You just downloaded it and ran it, introducing a beautiful, gaping hole for anyone who might've compromised a mirror or a developer's GitHub account. Your entire baseline is built on a foundation of "I trust the internet," which is a phrase that should get you fired from any serious organization.
Let's look at your methodology. "To save time I only run 32 of the 42 microbenchmarks." I'm sorry, you did what? You cut corners on your own test plan? What dark secrets are lurking in those 10 missing tests? Are those the ones that expose race conditions? Unhandled edge cases? The queries that actually look like the garbage a front-end developer would write? You didn't save time; you curated your results to tell a happy story. That's not data science; that's marketing.
And the test itself: 1 client, 1 table, 50M rows. This is a sterile, hermetically sealed fantasy land. Where's the concurrency? Where are the deadlocks? Where are the long-running analytical queries stomping all over the OLTP workload? Where's the malicious user probing for injection vulnerabilities by sending crafted payloads that look like legitimate queries? You're not testing a database; you're testing a calculator in a vacuum. Any real-world application would buckle this setup in seconds.
Now for my favorite part: the numbers. You see these tiny 1% and 2% regressions and you hand-wave them away as "new overhead in query execution setup." I see something else. I see non-deterministic performance. I see a timing side-channel. You think that 2% dip is insignificant? An attacker sees a signal. They see a way to leak information one bit at a time by carefully crafting queries and measuring the response time. That tiny regression isn't a performance issue; it's a covert channel waiting for an exploit.
And this... this is just beautiful:
col-1 col-2 col-3 point queries 1.01 1.01 0.97 hot-points_range=100
You turned on io_uring, a feature that gives your database a more direct, privileged path to the kernel's I/O scheduler, and in return, you got a 3% performance loss. You've widened your attack surface, introduced a world of complexity and potential kernel-level vulnerabilities, all for the privilege of making your database slower. This isn't an engineering trade-off; this is a self-inflicted wound. Do you have any idea how an auditor's eye twitches when they see io_uring in a change log? It's a neon sign that says "AUDIT ME UNTIL I WEEP."
You conclude that there are "no regressions larger than 2% but many improvements larger than 5%." You say that like it's a victory. You're celebrating single-digit improvements in a synthetic, best-case scenario while completely ignoring the new attack vectors, the unexplained performance jitters, and the utterly insecure foundation of your testing. This entire report is a compliance nightmare. You can't use this to pass a SOC 2 audit; you'd use this to demonstrate to an auditor that you have no internal controls whatsoever.
But hey, don't let me stop you. Keep chasing those fractional gains on your little desktop machine. It's a cute hobby. Just do us all a favor and don't let this code, or this mindset, anywhere near production data. You've built a faster car with no seatbelts, no brakes, and a mysterious rattle you "hope to explain" later. Good luck with that.
Oh, wonderful. Another blog post disguised as a public service announcement. "MySQL 8.0’s end-of-life date is April 2026." Thank you for the calendar update. I was worried this completely predictable, industry-standard event was going to sneak up on me while I was busy doing trivial things like, you know, keeping this company solvent. It’s so reassuring to know that you, a vendor with a conveniently-timed "solution," are here to guide us through this manufactured crisis. I can practically hear the sales deck being power-pointed into existence from here.
Let me guess what comes next. You're not just selling a database, are you? No, that would be far too simple. You're selling a "cloud-native, fully-managed, hyper-scalable data paradigm" that will "unlock unprecedented value" and "future-proof our technology stack." It's never just a database; it's always a revolution that, by pure coincidence, comes with a six-figure price tag and an annual contract that looks more like a hostage note.
You talk about weighing options. Let’s weigh them, shall we? I like to do my own math. Let's call your "solution" Project Atlas, because you're promising to hold the world up for us, but I know it's just going to shrug and drop it on my P&L statement.
First, there's the sticker price. Your pricing page is a masterpiece of abstract art. It's priced per-vCPU-per-hour, but with a discount based on the lunar cycle and a surcharge if our engineers’ names contain the letter ‘Q’. Let’s just pencil in a nice, round $200,000 a year for the "Enterprise-Grade Experience." A bargain, I'm sure.
But that’s just the cover charge to get into the nightclub. The real costs are in the fine print and the unspoken truths you hope I, the CFO, won't notice. Let’s calculate the "True Cost of Ownership," or as I call it, the "Why I’m Canceling the Holiday Party" fund.
So let’s tally this up with some back-of-the-napkin math, my favorite kind.
Initial License: $200,000 Migration (Internal Time): $350,000 Consultants (The Rescue Team): $150,000 Training: $50,000
The first-year "investment" in your revolutionary platform isn't $200,000. It’s $750,000. And that's assuming everything goes perfectly, which it never does.
Now, you'll promise an ROI that would make a venture capitalist blush. You’ll say we'll "realize 30% operational efficiency gains." What does that even mean? Do our servers type faster? Does the database start making coffee? To break even on $750,000 in the first year, those "efficiency gains" would need to materialize into three new, fully-booked enterprise clients on day one. It's not a business plan; it's a fantasy novel. You're promising us a unicorn, and you're going to deliver a bill for the hay.
So thank you for this… blog post. It was a very compelling reminder of the impending MySQL EOL. I'm now going to weigh my options, the primary one being to upgrade to a supported version of MySQL for a fraction of the cost and continue operating a profitable business.
I appreciate you taking the time to write this, but I think I’ll unsubscribe. My budget—and my blood pressure—can’t afford your content marketing funnel.
Alright, let's see what marketing has forwarded me this time. "Resilience, intelligence, and simplicity: The pillars of MongoDB’s engineering vision..." Oh, wonderful. The holy trinity of buzzwords. I’ve seen this slide before. It’s usually followed by a slide with a price tag that has more commas than a Victorian novel. They claim their vision is to "get developers to production fast." I'm sure it is. It's the same vision my credit card company has for getting me to the checkout page. The faster they're in, the faster they're locked in.
They’re very proud that developers love them. Developers also love free snacks and standing desks. That doesn't make it a fiscally responsible long-term infrastructure strategy. This whole piece reads like a love letter from two new executives who just discovered the corporate expense account. They talk about "developer agility" as the ability to "choose the best tools." That's funny, because once you've rewritten your entire application to use their proprietary query language and their special "intelligent drivers," your ability to choose another tool plummets to absolute zero.
Let's talk about their three little pillars. Resilience, they call it. I call it "mandatory triple-redundancy billing." They boast that every cluster starts as a replica set across multiple zones. “That’s the default, not an upgrade.” How generous. You don't get the option to buy one server; you're forced to buy three from the get-go for a project that might not even make it out of beta. It’s like trying to buy a Honda Civic and being told the "default" package includes two extra Civics to follow you around in case you get a flat tire.
Then there's intelligence. This is my favorite. It’s their excuse to bolt on every new, half-baked AI feature and call it "integrated." Their "Atlas Vector Search" is a "profound simplification," they say. It's simple, alright. You simply have no choice but to use their ecosystem, pay for their compute, and get ready for the inevitable "AI-powered" price hike. And now they're acquiring other companies and working on "SQL → MQL translation." This isn't a feature; this is a flashing neon sign for a multi-million-dollar professional services engagement. It’s the hidden-cost appetizer before the vendor lock-in main course.
And finally, simplicity. Ah, the most expensive word in enterprise software. They claim to reduce "cognitive and operational load." What this really means is they hide all the complexity behind a glossy UI and an API, so when something inevitably breaks, your team has no idea how to fix it. Who do you call? The MongoDB consultants, of course, at $400 an hour. Their "simplicity" is a recurring revenue stream. Just look at this masterpiece of corporate art:
The ops excellence flywheel.
A flywheel? That’s not a flywheel; that’s the circular logic I'm going to be trapped in explaining our budget overruns to the board. It’s a diagram of how my money goes round and round and never comes back.
They talk a big game about security, too. "With a MongoDB Atlas dedicated cluster, you get the whole building." Fantastic. I get the whole building, and I assume I'm also paying the mortgage, the property taxes, and the phantom doorman. This "anti-Vegas principle" is cute, but the only principle I care about is the principle of not paying for idle, dedicated hardware I don't need.
But let's do some real CFO math. None of this ROI fantasy. Let's do a back-of-the-napkin "Total Cost of Ownership" calculation on this "agile" solution.
So, our "simple" $100,000 database is actually a $570,000 annual cost with a $1.6 million escape hatch penalty. It won't just "carry the complexity"; it'll carry every last dollar out of my budget. Their formal methods and TLA+ proofs are very impressive. They've mathematically proven every way a cluster can fail, but they seem to have missed the most critical edge case: the one where the company goes bankrupt paying for it.
But hey, you two keep pushing those levers. Keep building those flywheels and writing your "deep dives." It’s a lovely vision. Really, it is. You're giving developers the freedom to build intelligent applications. Just make sure they also build a time machine so they can go back and choose a database that doesn't require me to liquidate the office furniture to pay the monthly bill.
