Am I missing something here, or is the only technical detail in the post "a trillion rows is a lot of data, maybe trying trinio will work this time"?

It feels like a lot of churn and not a lot of measurements or engineering.

If I was a user of this product I'd be really worried about the "We rewrote our software 5 months ago, but that didn't solve the issue we wanted to solve so we're doing it again, maybe this time we'll fix it" message of this post.

To me to key “insight” is that if you are going to spin up single VMs (or even groups) per-customer and then route queries, you need to be able to estimate the query cost first.

I know snowflake does this, they do the query optimization before sending it for execution. So it knows about how many resources will be needed (it can obviously be wrong).

Hi! Author here.

We engineered, then we measured and then we tried to make it work, probably for a too long of a time before we decided to completely scrap our current architecture and go back to the drawing board. Happy to answer more questions.

They are big on shipping slop at lightnigg speed. So this is not surprising. Checkout posts by their ceo on cringedin.
