The One Billion Row Challenge - Ruby Edition

Ruby edition of the 1BRC Java challenge.

I am using asdf to install ruby versions: 3.2.2 and 3.3.0

Tools

Gemfile

I included a profiler so you can tweak your implementation and create the fastest one!

bundle install

bundle exec ruby-prof create_measurements.rb -- 20

Note: initial usage for me was to create the measurements.txt file...

time_measurements_creation

Bash script to output 5 times per ruby version its time execution...

# 200 iterations
# create_measurements.rb script outputs measurements.txt file

./time_measurements_creation 200 create_measurements.rb

average_execution

Outputs metrics about the execution real time of the ruby versions...

./average_execution

calculate_average.rb

The main script. This is where the solution goes!

ruby calculate_average.rb
# Kolkata - min: 26.7, max: 36.7, avg: 31.690693763139457
# Guadalajara - min: 20.9, max: 30.9, avg: 25.91096780180013
