Does microservice experiment allocate cpu by scaling replicas?

[kuroro99]

hello, when I read the source code I found the k8s framemanager in cilantro only support the replicas. Is it true? If it is true, I wonder how can cilantro scaling the mongodb by increasing the replicas(the mongodb deployment in hotelreservation just bind to one pvc, and such database should be deployed by statefulset normally)?
I'm sorry that I didn't actually run cilantro, I just read the source code.
