1BRC Challenge
· 12 min read
One thing that recently got nerd the hell out of me was 1 billion row challenge. Citing the original site:
Your mission, should you decide to accept it, is deceptively simple: write a Java program for retrieving temperature measurement values from a text file and calculating the min, mean, and max temperature per weather station. There’s just one caveat: the file has 1,000,000,000 rows!
I was working on it after hourse and 1 week after taking on the challenge there are several conclusions worth writing about.
