I have plan to rebuild ElasticStack with 7 node (3 master + 4 Data), verison 7.6.x. Total data per month ~ 2TB.  
I have question, with Hot-warm-cold architecture, what is the compression ratio of each type?  
Can i use Hot and cold node only ? (dont use warm node) or must be have all hot-warm-cold or hot-warm ?  
Thank you
