My kneejerk reaction to the headline is ‘why would it?’.

It’s unsurprising to me that an AI company appears to have chosen exactly the wrong tool for the job.

Sounds like a deliberate attempt to avoid spinning up Redis, Kafka, or an outbox system early on.. and then underestimated how quickly their scale would make it blow up. Story as old as time.

Better to be successful with simple tech and have a minor 'blow up', then over engineer and go bust.
