One Billion Rows Challenge (Golang)

These are my solutions to the One Billion Row Challenge. I started with a simple unoptimised solution (solution1.go) which takes 2.24 minutes to an optimised and parallelised solution (solution5.go) which take 6.32 seconds.

NOTE:

• These results were produced on my PC (32GB RAM, 16 core CPU, linux/amd64)
• The major focus was on optimising the solution not necessarily following proper standards.

Here is my article on this for more details and results.

USAGE

• Run and benchmark all solutions

./1brc-go -file=<path_to_weather_data_file>

• Run and benchmark a specific solution

./1brc-go -file=<path_to_weather_data_file> -solution=1

• Run CPU profile

./1brc-go -file=<path_to_weather_data_file> -solution=1 -cpu-profile=cpu.prof
