Author of the blog post here. Cloud Source Repositories currently supports very large repositories. The same backend scales to the needs of the Android open source project, which regularly checks in massive binary files. There are many APKs and VM images in the Git repositories we host. However, Cloud Source Repositories does not support LFS or the mirroring of LFS content. LFS is not deeply integrated into Git, creating usability problems. Because the content is not part of the object graph of the repository, you have to decide in advance to use Git LFS. You don't get the benefit in existing repositories with large files. You also can't back out --- once you're using Git LFS on a medium-sized file, you can't change your mind and instruct Git to send it inline in fetches, without rewriting history, which breaks existing clients that have cloned the repository. For the same reason, history mining commands like "git blame" and "git log -S" don't have access to the object. In addition, it complicates migrating to another host. Usually in Git, you can take out your content by running "git clone --mirror one-url and then "git -C directory.git push --mirror another-url". With Git LFS, this copies over the pointer files but not the underlying large file content and you must remember to take extra steps to instruct the new host about where the blobs are stored. Google's Cloud Source Repositories team believes that Git itself needs to deal better with large files. The first step of this work within the Git project has been partial clone, which is supported in Cloud Source Repositories and in the public Git 2.17 release (for best results, please use Git 2.19, released September, 2018). If you run "git clone --filter=blob:limit=512M <url>", files larger than 512M will be omitted from the initial clone and fetched automatically on demand when needed (for example during checkout operations). See https://crbug.com/git/2 https://crbug.com/git/2 for more details about this feature. We are continuing to work with the community on adding other features related to large file support into Git.
