What you'll learn

Large Git repositories can become difficult to manage, leading to slower workflows, increased storage costs, and reduced developer productivity. In this course, Performance Engineering for Large Git Repos, you’ll gain the ability to diagnose, tune, and sustain Git performance in massive enterprise codebases. First, you’ll explore how to measure repository bloat using git-sizer and git rev-list to identify oversized objects, deep histories, and structural bottlenecks. Next, you’ll discover how to implement Sparse Checkouts, Partial Clones, Scalar, and Git LFS to dramatically reduce local disk usage and network latency. Finally, you’ll learn how to configure background maintenance with git gc and git repack to sustain long-term repository health and assess your tooling’s readiness for the Git 3.0 reftable backend. When you’re finished with this course, you’ll have the skills and knowledge of Git performance engineering needed to keep large repositories fast, healthy, and ready for the future.
