Crazy day, I indexed 30GB file having 53 million lines of json data to elastic. Then I tried kibana with it it was really enjoyable after doing it with my drink. Link to kibana is

Link to exastic is

the most tough was to unzip 5GB file using all cores, it was bz2 file. I used pbzip2 but it didn’t worked in my case. Then I found lbzip2 -d myfile.json. It was really fast and used my all cores efficiently. It turned out to be 30GB then. After that how could we insert it to elastic, as I am very new to this I found esbulk and started with this. I inserted 45 million entries then It became too slow. Now I had no option other and stopping it right there.

Than I came up with new idea of tail -n No of rest of the entries and inserted them back. I successfully did it. Now I can say I kind of know big big data….. 🙂 feeling happy
