Summary
This book excerpt introduces "High Performance Git" by Ted Nyman, which explores Git not just as a version-control tool but as a layered system including a content-addressed database, filesystem cache, graph walker, and transfer protocol. The book covers objects, refs, the index, history traversal, packfiles, maintenance, sparse working trees, partial clone, transport, repository scale, diagnosis, configuration, and recovery. It is aimed at engineers who need Git to perform well as repositories, histories, and teams grow larger.
