I'm new to Elasticsearch, and calculating the price when I use Elastic Cloud.
I noticed that I can use multiple data nodes only when I use data nodes with the highest RAM settings.
Why is it?
Does it mean that it's meaningless to use multiple data nodes with lower RAM settings?
I have only 2~3GB data, and going to build a searching application (not logging data).
But I think I can improve its searching performance with multiple data nodes.
(Tell me if my idea is wrong)
