11/08/2022, 6:53 PMQuestion from Natan on YouTube: what is the best approach to run a database? As a pod? Or inside a machine? Or some paas service?

11/08/2022, 7:06 PMPaaS is easiest if it works, but sometimes that’s not viable, in which case use a stateful set or an appropriate Kubernetes Operator
Natan Yellin
11/08/2022, 7:07 PMThere’s a misconception that Kubernetes isn’t for stateful sets, despite the fact that large companies do run stateful sets on kubernetes
Natan Yellin
11/08/2022, 7:08 PMIf you’re running Prometheus on Kubernetes, for example, you’re already running a stateful set which is storing all your metrics!

11/08/2022, 7:09 PMTo give a concrete example of the tradeoffs, we’re using a postgres as a service for the robusta.dev cloud, but for our on-prem customers we deploy a postgres instance inside their clusters.
So there is no one solution! Depends on the scenario

11/11/2022, 5:53 PM@Natan Yellin have you done testing around limits with different kernel versions? It looks like there have been several CFS kernel changes over the past few years, with some changes correlated with Kubernetes issues.

11/12/2022, 7:36 PM@Dave Thompson I haven’t tested enough, but afaik the fundamental issue remains. There was a rather nasty CFS bug once, but the issue with limits occurs regardless.
