Git rebase is more than a way to clean history. It’s a way to take ownership of what stays, what goes, and how your repository tells its story. When you merge without thinking about data control, you inherit every mistake, secret, and debug artifact that ever slipped in. When you rebase with intent, you decide what your future codebase contains.
Data retention inside Git is not just about disk space. Every commit is preserved unless you rewrite it. That means sensitive tokens, outdated configs, or experimental features you thought were gone may still exist in the history. Rebasing, paired with filtering, gives you the power to prune with surgical precision.
The core idea is simple: keep what matters, drop what doesn’t, and structure your branch history to be safe, clear, and lean. Interactive rebase lets you reorder, squash, and edit commits. You can remove entire pieces of history before they spread to public branches. You can compress noise into meaningful milestones that anyone can trace without wading through clutter.
