Thanks for bringing singleflight to my attention. However, if I'm not wrong, it doesn't seem to fully solve the problem.
If after uploading, I call singleflight.Do, and pass the file name and the compression function, when users requests a file, should I call singleflight.Do and pass the requested file name and the compression function again? Doesn't that mean I can never forget a key otherwise the file may get compressed multiple times?
