I have one more question, and this is about how master election is done if I have 3 nodes(2master+data and 1 dedicated master).
I have gone through this post, where you have given some details about using such configuration(3 nodes startup) for small clusters. With 10GB/day and holding 3 TB of index data, I believe my cluster is also a small one. I have also gone through master-election documentation here.
Since I don't want my data nodes to be doing extra work, I would like to have my only dedicated master node to be the actual master. How can I make sure that happens during Master-Election? Or is this the default behavior?
