> > I've decided to remove the cpu requests and specify instead `-XX=ActiveProcessorCount=2` in the default jvmOpts. maybe we can reduce this to 1? some older laptops don't have 8 cores. > I think this approach is better because the request approach consumed at least 8 CPUs. This means that, by default, the chart would not start in clusters with less than 8 CPUs in total, which can be very common in local k8s installations (like minikube or microk8s) and also in small aws machines. I am not familiar with now minikube/microk8s maps CPUs to host, just to clarify are these 8 cores virtual or the ones that are physical (include hyperthreading)? > * Nodes with few cpus will have installations that use quite more threads than cpus. This could introduce performance issues due to high context switching when several queries are being executed at the same time, but the system should run well enough to do some tests, which is the common use case of this kind of installations. I am less worried about running multiple queries at the same time, given that this setting is more for quickstart setups. -- This is an automated message from the Apache Git Service.
