Editing Delta encoding (section)

{{main|Git (software)}}

The Git source code control system employs delta compression in an auxiliary "[http://git-scm.com/docs/git-repack git repack]" operation. Objects in the repository that have not yet been delta-compressed ("loose objects") are compared against a heuristically chosen subset of all other objects, and the common data and differences are concatenated into a "pack file" which is then compressed using conventional methods. In common use cases, where source or data files are changed incrementally between commits, this can result in significant space savings. The repack operation is typically performed as part of the " git gc"<ref>{{Cite web|url=https://git-scm.com/docs/git-gc|title=Git - git-gc Documentation|website=git-scm.com|accessdate=November 9, 2024}}</ref> process, which is triggered automatically when the numbers of loose objects or pack files exceed configured thresholds.

The format is documented in the pack-format page of the Git documentation. It implements a directed delta.<ref>{{cite web |title=Git - pack-format Documentation |url=https://git-scm.com/docs/pack-format |website=Git documentation |access-date=13 January 2020}}</ref>
