Hi Team First, this is a cool project. Excited to be looking into it and learning more. Noobie question… I have looked at the architecture and I see some older docs that show the the controller consists of two components: Zookeeper and Helix. If we choose a Kubernetes deployment it seems Kubernetes does the same things that Helix does. Am I correct in assuming the Kubernetes deployment does not include Helix?

k8s and helix serve different purposes in this architecture. helix does metadata state management to ensure that the data segments are distributed properly across the pinot servers - k8s manages the nodes themselves (e.g. makes sure that you have N servers and M brokers running). basically, k8s manages nodes and helix manages state

yes as almog mentioned, K8s and Helix doesn't do the same thing

Thank you for the information. That’s clear and helpful.
