I am using elasticsearch 2.x . I have total 9 nodes with M4.4xlarge and I want to downsize to lesser nodes . Total docs I need to store 2 Million Per doc size = 30KB With this stats I Believe Elasticsearch would need
30 KB * 2000000 docs = 60000000 KB = 60000 = 60GB ~
However when I have indexed all docs I see its 500GB data. I am confused as how my index has grown this much could someone please give me some insights to work upon
