I haven't read the article, just the headline, and what a strange...challenge...this is. Like, 1bil rows of CSV? JSON objects? Billion XML records? What does "process" mean? Parse and toss? Transform?

- bheadmaster 3y ago> I haven't read the article Well, you should've - it's very clearly explained: The text file has a simple structure with one measurement value per row: Hamburg;12.0 Bulawayo;8.9 Palembang;38.8 St. John's;15.2 Cracow;12.6 ... The program should print out the min, mean, and max values per station, alphabetically ordered like so: { Abha=5.0/18.0/27.4, Abidjan=15.7/26.0/34.1, Abéché=12.1/29.4/35.6, Accra=14.7/26.4/33.1, Addis Ababa=2.1/16.0/24.3, Adelaide=4.1/17.3/29.7, ... }
