This script showcases downloading a file over HTTP in parallel or by doing a GET request in Golang.
The file is located at https://d37ci6vzurychx.cloudfront.net/trip-data/yellow_tripdata_2018-05.parquet and has 125MB. In case this file will be removed at one point, feel free to replace the URL.
To download the file sequentially in 1 GET request:
go run main.go -sTo download the file in 8 concurrent requests:
go run main.go -p 8You can also do 1 GET request by spinning only 1 worker, but the reason I have a separate method is to showcase the difference between a simple GET request and an HTTP Range request.
