wordmap

1 14 5.3 Ruby

Wordmap is a simple way to lookup data directly from disk, bypassing RAM. It uses pread (no buffering), and takes advantage of SSD's constant seek time. The data is stored in equal size "cells" making it easy to calculate where things are located based on vectors.

Project mention: Is sequential IO dead in the era of the NVMe drive? | news.ycombinator.com | 2023-05-09

We had a use case at one of former jobs where we had to read hundreds of megs of static data (vendored with the app), but it didn't have to be super fast and we didn't want to waste any RAM on it. Since everything is on SSDs, I wrote a lib[0] that was just seeking sorted files with pread and binary search. Worked perfectly for our needs.
