Before the deployment of the Denodo Embedded MPP, you must define in the values.yaml how many MPP Workers, presto.numWorkers, will run. But you can scale the Denodo Embedded MPP later, by increasing or decreasing the number of MPP Workers, pod replicas, depending on the workload.

It is strongly recommended to use pod-based scaling together with node-based scaling to coordinate scalability of the pods with the behavior of the nodes in the cluster, since our recommendation is to use one single node for each MPP worker. This way, when you need to scale up, the cluster autoscaler can add new nodes, and when scaling down, it can shut down unneeded nodes.
