What is the difference between client node and master node in Elasticsearch?
I want to understand the difference between a client node and a master node in Elasticsearch. I'm confused about their roles and responsibilities within the Elasticsearch cluster.


What happens when master node goes down?
Could you elaborate on the potential consequences of a master node going down in the context of a cryptocurrency network? How does it impact the overall functionality and security of the system? Is there a contingency plan in place to minimize disruption in the event of such an occurrence? And finally, what steps can network participants take to prevent or mitigate the risks associated with a master node downtime?
