I'm asking what is the better way to rotate my index. I heard about ILM policy.
I did some test but as I have only 3 data nodes, and as I want one replica, I can't have a Hot/Warm/Cold architecture because this would require 6 more nodes (a node can't be at the same time Hot, Warm and Cold)
So, currently, my ILM policy only works with hot nodes.
Does it makes sense to you ? Or does I have to find another solution ?
Thanks for your feedback !
