1brc implementation

This is my implementation of the one billion row challenge in Zig. In zig with the basic implementation, it takes about 0.06 seconds on the 45k dataset.

zig build -Doptimize=ReleaseFast
time ./zig-out/bin/1brc 2> output.log 
0.06s user 0.49s system 99% cpu 0.559 total

Generate data

gcc create-sample.c -lm -o generate-data
./generate-data 1000000000

Optimization

• Tweak hashmap
• Try SIMD
