How to download and extract .tar.zst files without saving?
Hey folks, I'm trying to figure out if there's a way to download a snapshot image as a .tar.zst file and unzip (extract) it while it's downloading. The aim is to avoid saving the .tar.zst file to my hard disk entirely. Any tips on how to achieve this?

1One approach to achieve downloading and extracting a .tar.zst file in one go is by using a command line pipeline that avoids writing the compressed file to disk. You can try this command as a starting point:
wget -c http://link.tar.zst -O - | tar -I zstd -xf - -C . --strip-components=3
This command uses wget to download the file and pipes it directly to tar, which extracts the contents without saving the compressed file first . Keep in mind, if you're dealing with multiple files from Polygon, as mentioned, you'll need to repeat this command for each file you want to download and extract .
