Is this the talk? Looks like this is it https://www.youtube.com/watch?v=5dpLVvRpPPs
The an older version of the same talk. Things have moved a bit since, Java 21 and such, but mostly the same.
Readit NewsInteresting, no mention of Scala at all. Did Netflix say goodbye to Scala altogether?
We never really used it, aside from some niche use cases. It’s always been Java primarily.
>Netflix observed a 20% increase of CPU usage on JDK 17 compared to JDK 8. This was mostly due to the improvements in the G1 garbage collector.
Help me here, why do GC improvements cause CPU increase?
It’s a 20% improvement. So less time spent on GC.

Falcor was developed at the time Facebook was developing GraphQL in-house. It has similar concepts, but never took off the way GraphQL did.
