The One Billion Row Challenge Shows That Java Can Process a One Billion Rows File in Two Seconds
Briefly

The 1BRC is a coding challenge based on a deceptively simple task: parsing temperature measurement values from a text file and determining the min, max, and mean temperature for each weather station present. The caveat: the file has 1,000,000,000 entries!
Start with the README file and by cloning the repo. Try to implement your solution then see what others tried as well - it's all about the learning in the end.
