I have a git repository maintaining one large json file (along with
several other small files). With commits for large json file, the
repository become bigger and bigger, so I tried to run command "git gc
--prune=now --aggressive" to reduce disk usage, then I found .git
folder size did not change. I had wonderful experience with git gc
against files around 10M to 20M, and I am wondering if there is any
configuration need to tweak for large text files?

Here I have more details:
1. Json file size: 1G

Git won't try to delta-compress anything over 500MB by default. Try:

 git config core.bigfilethreshold 2G
 git gc --aggressive

-Peff

It works! Thank you so much!
