Thanks for the detailed explanation erick. I did a little math as you suggested. Just wanted to see if i am doing it right. So we have around 4 billion docs in production and around 70 nodes.
To support the business use case we have around 18 fields on which we have to enable docvalues for sorting. FieldType totalFields Size of field TriIntField 2 4 bytes StrField 7 20 bytes IntField 1 4 bytes Bool 1 1 bytes TrieDateField 2 10 bytes TextField 5 10 bytes Some of them i approximated the bytes like fot strField and textField based on no. of chatacters we usually have in those fields. I am not sure about the TrieDate field how much it will take. Please feel free to correct me if i am way off. so acc. to the above total size for a doc is = 2*4 + 20 *7 + 4 + 1+20+50 = 223 bytes. So for 4 billion docs it comes to approximate 892000000000 bytes or 892 gb. Does that math sound right or am i way off ? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
