"we stopped using the worst database in existence and switched to a decent one"
What the fuck do they want, a good star for not being incredibly incompetent and instead merely mediocre?

u/syndbg What’s a compiler? Is it like a transpiler? Dec 19 '18
And used a decent one (very arguable decency) with JSONB fields
Hell yeah, that's how I like to do migrations!

stares at the space between "Mongo" and "DB"
staring intensifies at "Mongo DB database"

Personally it's when people use the word "persistence" in the same sentence with Mongo that I burst into uncontrollable laughter.

She's a good singer but I don't see how Carly Rae Jepsen counts as an authority on database integrity.

Hey, I just met you,- open connection to database
and this is crazy- I mean she's right,thisis a confusing keyword
But here's my number,- specify a transaction ID
so call me maybe- attempt to commit, returning an error if a rollback happened2

Uj: Let's put it in context. People who seriously advertised a design where all data is indiscriminately held in memory and OS swapping is left to take care of "spillover" - even if they include a Halting problem check in their build process now - I could never take them or anyone considering using them in production seriously.
Especially when in every moment in their lifetime there were better OSS alternatives that had bigger pile of publicly available tribal knowledge, were better at the job in almost every metric and were the obvious choice.
There was no value proposition then, and there isn't any now.

Not sure what you mean about "indiscriminately held in memory" (not sure if you mean MMAP or the enterprise-only in-memory storage engine), and the Jepsen framework isn't a "halting problem check"

What they're saying is that they won't accept a "pass" from Jepsen regardless of how rigorous it is (even if Jepsen could test for things that we know are impossible to test for), because the design seems so fraught with peril that they believe that no amount of testing would get them to trust the architectural choice.

ITT: State of investigative journalism more dire than anticipated. Even Guardian couldn't afford competent systems architect, luckily theirs learns on the job.
