Has anyone tried deploying Pinot over a service mesh like envoy or istio? If yes, could you please share any learnings? Even better if you are integrating with Presto or Looker.

we’ve 1/2 done this over envoy, but no presto integration yet. every host is registered with envoy and we access controllers and brokers via envoy. but broker <> server communication is done directly by host name since you need to speak to a specific instance. but that is likely also do-able over envoy

I see. If I understand this correctly, any internal communication is directly by host name and any external connection to broker or controller goes via envoy?

exactly
