I had not heard this before but...

cgroup awareness of OOM killer
Linux Kernel 4.19 (October 2018) introduced cgroup awareness of OOM killer
implementation which adds an ability to kill a cgroup as a single unit and
so guarantee the integrity of the workload.

That's from
https://en.m.wikipedia.org/wiki/Cgroups

Of course you still need to identify and configure your cgroups
effectively. It seems overdue to make the two tools cooperate but as others
pointed out, they have different origins. And it's another one of those
things handled differently in the data center from the desktop.

Some resource manager (ulimits, control groups [1], what have you)
