In the FDB architecture document, https://apple.github.io/foundationdb/configuration.html#guidelines-process-class-config, it is stated that “…The recommended minimum number of
class=transaction (log server) processes is 8 (active) + 2 (standby)…”.
I am now running a cluster with 60 Kubernetes Storage pods (in a single DC) with each pod having 3 storage processes. I would like to know how I should scale the number of the log processes correspondingly. Certainly different write workload would require different number of the log processes. So the related question is, what are the performance metrics that I can found in the status.json that allow me to determine whether the log processes get saturated or not.
