Hi everyone!
I have a quick question:
I create random JSON files and send them to elasticsearch.
When I check the sizes of the files using du -h in my centos machine and when I check the stats in the \_stats section I get major differences between the results.
for example:
file number --- du -h size ------ /\_stats
100 --------------- 404 kb ---------- 297 kb
1000 ------------- 4096 kb -------- 1200 kb
3000 ------------- 12 MB ----------- 3.3 MB
Now is it reasonable that storing somthing in elastic is so much smaller than on linux machine?
Why is the gap is so big?
