How Git Stores Data Hackernoon All the data that git needs is stored in the .git folder. as a git user, you have no business changing those files, but for the purposes of this article, we’ll take a look inside to see how git stores the data. All the data that git needs is stored in the .git folder. as a git user, you have no business changing those files, but for the purposes of this article, we’ll take a look inside to see how git stores the data. just after creating the repository with git init, you’ll find inside:.
How Git Stores Data Hackernoon We type git commit or git push, but behind the scenes git is managing a powerful object database that makes it fast, distributed, and resilient. in this guide, we’ll break down git’s internals in plain english, explain how it stores data, and show you some hands on commands to explore it yourself. Git stores data as objects inside the .git objects directory, organized using sha 1 hashes for efficient access. Instead, git thinks of its data more like a set of snapshots of a mini filesystem. every time you commit, or save the state of your project in git, it basically takes a picture of what all your files look like at that moment and stores a reference to that snapshot. Git doesn’t save the whole project from scratch each time. instead, it saves only the new or changed files, and for the rest, it simply reuses what’s already been saved before.

In my case, everything ‘clicked’ as soon as i read about the internal data model used by git. you see, git is a kind of a database, and one would never be able to work with sql, for example, without knowing what a table, record, etc. is. Git stores content in a manner similar to a unix filesystem, but a bit simplified. all the content is stored as tree and blob objects, with trees corresponding to unix directory entries and blobs corresponding more or less to inodes or file contents. But have you ever stopped to wonder how git actually stores all of this information? unlike traditional version control systems that rely on databases or track file differences, git uses an elegantly simple approach: a content addressable filesystem. Git’s design is elegant yet often misunderstood. this article will peel back the layers, explaining git’s core mechanisms, storage model, and how everyday commands work at a fundamental level.
